Research Projects in Medical Imaging

Estimation of Flow Parameters from X-ray Data

Estimation of Flow Parameters from X-ray Data

Recognizing stenosis in angiographic images is a quite difficult task. Most methods are only 2D so that overlapping, foreshortening or a bad perspective of the view causes a false diagnoses. The aim of this project is to reconstruct the blood flow from 3D X-ray data to get a realistic and patient specific computer fluid dynamic simulation of the blood flow. With this any type of images concerning blood flow can be simulated. Also the perspective of these images can be chosen by the user without taking X-ray images from the patient.
Automatic Progression Tracking of Skin Lesions

Automatic Progression Tracking of Skin Lesions

The aim of this project is to investigate, design, and implement a novel prototype device capable of acquiring the skin surface in multiple spectral bands and generating a 3D reconstruction of it. The reconstruction will allow the system to compare quantitatively the results with any previous one, and show the physician the evolution of a skin lesion. Moreover, the software will also search for melanocytic skin lesions suspicious for melanoma using established medical criteria, and assist the physician to check these suspicious lesions in more detail through the multispectral information. This will provide the physician with a tool that documents the evolution of skin lesions allowing to follow these objectively over time irrespective of common problems like tanning, body weight changes, deformation, etc. The final goal is to improve skin cancer detection stages when therapeutic intervention results in survival rate close to 100%, as well as to provide a tool for the quantitative evaluation of skin cancer types such as cutaneous lymphoma that have to be monitored over time. This approach should increase not only the detection sensitivity but also specificity; an important notion particularly for patients with several atypical naevi for which the false negative rate is over 80%. The scanner will then also be a tool to reduce the number of unnecessary biopsies.
Patient Position Detection for SAR Optimization in Magnetic Resonance Imaging

Patient Position Detection for SAR Optimization in Magnetic Resonance Imaging

Although magnetic resonance imaging is considered to be non-invasive, there is at least one effect on the patient which has to be monitored: The heating which is generated by absorbed radio frequency (RF) power. It is described using the specific absorption rate (SAR). In order to obey legal limits for these SAR values, the scanner's duty cycle has to be adjusted. The limiting factor depends on the patient's position with respect to the scanner. Detection of this position allows a better adjustment of the RF power resulting in an improved scan performance and image quality.
In this project, we use real-time methods for accurately detecting the patient's position with respect to the scanner. MR data of thirteen test persons acquired using a new "move during scan" protocol which provides low resolution MR data during the initial movement of the patient bed into the scanner, is used to validate the detection algorithm. When being integrated, our results would enable automatic SAR optimization within the usual acquisition workflow at no extra cost.
Future developments seek an even more robust and accurate detection of more features of the patient than just head, neck, lung, and feet.
Analysis and Visualization of Colon Motility

Analysis and Visualization of Colon Motility

The objective of this project is to develop a computer aided diagnosis tool to detect colon motility disorders by using cine MRI. The necessary image processing consists of breathing motion compensation, colon segmentation and modelling the natural motion of the colon. New algorithms for measuring the isometry of colon extension should be developed. A prototype software has been already implemented and should be improved in terms of usability.
Towards Deforming Motion Compensation Algorithms in Positron-Emission-Tomography

Towards Deforming Motion Compensation Algorithms in Positron-Emission-Tomography

Subject of this project is the development of dedicated reconstruction algorithms for PET which take patient movements into account. Positron-emission-tomography (PET) is nowadays a well-established tool for diagnosing, staging and monitoring diseases in patients. However, due to the long acquisition times which are necessary for a PET scan, patient movements are often unavoidable. Patient motion during data acquisition can cause image blurring and even severe artifacts in the reconstructed image, thus posing a significant problem for further diagnosis and treatment. To date, available algorithms have been tested only on synthetic data since they rely on general transformation data of the patient which are currently not practically available. We aim at developing algorithms that work on partial transformation data that will be delivered e. g. by new laser cameras or com-bined PET/MRT machines.
Intra-operative Human Computer Interaction and Usability Evaluations

Intra-operative Human Computer Interaction and Usability Evaluations

Computerized medical systems play a vital role in the operating room, yet surgeons often face challenges when interacting with these systems during surgery. In this project we are aiming at analyzing and understanding the Operating Room specific aspects which affect the end user experience. Beside operating room specific usability evaluation approaches in this project we also try to improve the preliminary intra-operative user interaction methodologies.
Registration of Angiographic Images

Registration of Angiographic Images

Angiographic images visualize vascular structure in different modalities like X-Ray, CT, or MR data sets. In many medical applications, a registration and proper visualization of the data sets, especially the vasculature is useful for a better navigation. The focus of this project lies on 2D/3D registration of angiographic data where intensity-based, feature-based, and hybrid approaches are evaluated, the latter two of them requiring an accurate 2D and 3D segmentation of the data. The main clinical partner is the radiology department of the Universitätsklinikum Großhadern (Ludwig-Maximilian Universität München) , industrial partner is Siemens Medical Solutions, Forchheim.
Cardiac C-Arm CT

Cardiac C-Arm CT

Tomographic reconstruction from rotational cone-beam X-ray data is only solved for static objects of interest (like the abdominal region). In cardiac imaging, a rotational angiography sequence takes about 4 to 6s and therefore spans several heart beats. Since such an acquisition scheme forces a trade-off between consistency of the scene and reasonable baselines between camera positions, standard reconstruction techniques fail at recovering the 3D+t scene. We propose a new reconstruction framework based on variational level sets including a new data term for symbolic reconstruction as well as a novel incorporation of motion into the level set formalism. The resulting simultaneous estimation of shape and motion proves feasible in first experiments.
Reconstruction and Registration of Histology and Phase Contrast Images for Clinical Validation of Imaging Modalities

Reconstruction and Registration of Histology and Phase Contrast Images for Clinical Validation of Imaging Modalities

Before its introduction into the hospital, a new imaging modality has to be validated. In other words, appearing structures need to be correlated to the imaged tissues. Such a cross validation is only meaningful when performed against the gold standard which is histology. Currently, cross validation is performed by qualitative comparison of 3D datasets to 2D histology slices. Since the acquisition of a consistent 3D histology volume is a challenging task, its comparison to the corresponding dataset always remained qualitative.

The classic histology procedure can be divided in four steps: pre processing, cutting, post processing and imaging of the tissues. In the first step, the sample is chemically processed to preserve the tissues and is then embedded in a paraffin block. By using a microtome, it is cut in very thin slices, and put on a glass slide. During post processing the sample is stained to enhance the structures of interest. The imaging is performed with a camera mounted in a microscope, or with a dedicated scanner. Several difficulties inherent to this process can have a dramatic influence on the quality of the reconstructed histology volume. For instance, since the cutting process is done manually, problems like flipping, bending or ripping of the slides may happen. If the knife starts to wear off, some banding will appear over the slices. Moreover, a few slices could be missing. Finally since the staining color is time dependent, variation in the color of the slices can occur.

In this project, we propose to improve the histology procedure and to develop methods towards a consistent reconstruction of 3D histology volumes.
Multi-View Deconvolution

Multi-View Deconvolution

Biomedical images are often degraded during image acquisition. Two very common degradations that occur in many biomedical imaging modalities are blur and noise. Corrupted images are more difficult to interpret by the physician or researcher and so the goal is to restore the original image. Blurring can be mathematically modeled by convolution, and within this model the blur is characterized by the point-spread-function (PSF). Two kinds of blur can be distinguished: shift-invariant and shift-variant blur. Shift-invariant blur is constant over the whole image, and shift-variant blur is characterized by a PSF that is dependent on the spatial position in the image. The process of restoring a blurred image is referred to as deconvolution in the literature. There are two major classes: non-blind deconvolution algorithms that assume that the PSF is known in advance and blind deconvolution algorithms that do not need any a priori knowledge regarding the PSF. We propose a new blind deconvolution method. As an input, our method takes several observations of the same scene, each of them acquired from a different point of view, and their respective spatial transformations. The transformations are either directly known by dedicated image acquisition systems, or they can be retrieved by image registration or tracking. The output is the restored original image and PSF. This multi-view setting occurs frequently in practice. However, most of the methods available in the literature do not specifically take advantage of the information provided by this setting. This project aims at unparameterized blind deconvolution in the shift-variant case.
Mosaicing

Mosaicing

The creation of mosaics is an interesting application, which leads to many challenging theoretical and practical problems. In this project, we are mainly focusing on viewing the mosaicing as a multiple image alignment task. Therefore, pairwise registration methods with a consecutive normalization and simultaneous registration techniques are in focus. Espcically the simultaneous alignment of images for mosaicing seems very promising. We earlier developed a new type of multivariate extension for similarity measures, which led to a whole new class metrics. They are specifically adapted for their usage in mosaicing, but can also be used for general multiple image alignment tasks, e.g. population studies. Our main interest lied so far on the combination of several ultrasound images. To this end, we are benifiting from a quite recent development in ultrasonographic research; the development of advanced 2D array ultrasound transducers. Their new fabrication process allows for higher resolution images with a higher quality resulting from the increased frequency spectrum that they can be operated with. The instantaneously acquired ultrasound volumes serve as input for our mosaicing framework, where they will be compounded to one lager volume.
Assessment of Fluid Tissue Interaction Using Multi-Modal Image Fusion for Characterization and Progression of Coronary Atherosclerosis

Assessment of Fluid Tissue Interaction Using Multi-Modal Image Fusion for Characterization and Progression of Coronary Atherosclerosis

Coronary artery diseases such as atherosclerosis are the leading cause of death in the industrialized world. In this project, we develop computational tools for segmentation and registration problems on intravascular images including IVUS (Intravascular Ultrasound) and OCT (Optical Coherence Tomography). One sample component of this project is Automatic Stent Implant Follow-up from Intravascular OCT Pullbacks. The stents are automatically detected and their distribution is analyzed for monitoring of the stents: their malpositioning and/or tissue growth over stent struts.
Catheter Extraction in Abdominal Fluoroscopic Image Sequences

Catheter Extraction in Abdominal Fluoroscopic Image Sequences

This work's focus lies in catheter and guide wire extraction from abdominal fluoroscopic sequences. Due to the fact that fluoroscopic X-ray images are of low quality and suffer from a lot of background clutter in the abdominal area the task we are working on is very difficult and not yet solved by the community. The detection process is very important since a properly detected catheter or guide wire is required by many applications that have been proposed in the last few years. One of the major goals is the enhancement of the navigation during abdominal cathterizations in order to reduce the time of interventions and thus the radiation exposure for the patient and especially the physician.
Motion Compensation for Catheterizations

Motion Compensation for Catheterizations

In many minimally-invasive interventions, catheters are inserted into the body and guided to a region of interest with the help of fluoroscopic imaging (low-dose X-ray image sequences). Due to patient motion, the navigation can be disturbed, and the physician needs a longer time for treatment. This is hazardous in terms of radiation for both, physician and patient. In order to overcome these problems, suitable image-based compensation methods to resolve (non-) rigid motion can be applied. In this project, patient motion is analyzed and suitable compensation algorithms are developed.
Simulated Ultrasound

Simulated Ultrasound

We are simulating Ultrasound images from CT volumes by assuming a correlation between Hounsfield units and acoustic impedance. Rays are cast trough the CT volume to simulate the US image formation. Simulated Ultrasound from CT can be used for CT/Ultrasound registration by comparing a real US image to simulated ones. Another application of simulated US is training.
Freehand SPECT for Sentinel Lymph Node Localization

Freehand SPECT for Sentinel Lymph Node Localization

Nuclear medicine imaging modalities assist commonly in surgical guidance given their functional nature. However, when used in the operating room they present limitations. Pre-operative tomographic 3D imaging can only serve as a vague guidance intra-operatively, due to movement, deformation and changes in anatomy since the time of imaging, while standard intra-operative nuclear measurements are limited to 1D or (in some cases) 2D images with no depth information. To resolve this problem we propose the synchronized acquisition of position, orientation and readings of gamma probes intra-operatively to reconstruct a 3D activity volume. In contrast to conventional emission tomography, here, in a first proof-of-concept, the reconstruction succeeds without requiring symmetry in the positions and angles of acquisition, which allows greater flexibility and thus opens doors towards 3D intra-operative nuclear imaging.
Semi-Automatic Patellar Cartilage Segmentation

Semi-Automatic Patellar Cartilage Segmentation

Development and refinement of a software system for semi-automatic segmentation of the patellar cartilage is the main goal of this project. By providing tools for sub-pixel accurate edge tracing, automatic contour completion, and adequate visualization, a remarkable speed-up of the physicians segmentation process can be achieved. Also, improved exactness can be reached for cartilage segmentation if expertise and automation are merged in a meaningful way.
Camera Augmented Mobile C-arm

Camera Augmented Mobile C-arm

Mobile C-arms are an everyday tool to acquire X-ray images in the operating room during surgery. The Camera Augmented Mobile C-arm (CamC) system augments a regular mobile C-arm by a video camera for X-ray and video image overlay. Thanks to the mirror construction and one time calibration of the device, the acquired X-ray images are co-registered with the video images without any further calibration or registration during the intervention. The CamC system can support a wide range of potential clinical applications, such as needle guidance, interlocking of intramedullary nails, and pedicle screw placement.
Assessment of Knee Cartilage

Assessment of Knee Cartilage

Degeneration of knee joint cartilage is an important and early indicator of osteoarthritis (OA) which is one of the major socio-economic burdens nowadays. Accurate quantification of the articular cartilage degeneration in an early stage using MR images is a promising approach in diagnosis and therapy for this disease. Particularly, volume and thickness measurement of cartilage tissue has been shown to deliver significant parameters in assessment of pathologies. Here, accurate computer-aided diagnosis tools could improve the clinical routine where image segmentation plays a crucial role. In order to overcome the time-consuming and tedious work of manual segmentation, one tries to automate the segmentation as much as possible. We focus on novel atlas-based segmentation methods for knee cartilage as well as improve today’s clinical routine of manual segmentation methods. In addition, we try to evaluate different methods for the assessment of parameters such as volume and thickness which could allow computer-aided diagnosis of knee cartilage pathologies in an early stage.
Laparoscope Augmentation for Minimally Invasive Liver Resection

Laparoscope Augmentation for Minimally Invasive Liver Resection

In recent years, an increasing number of liver tumor indications were treated by minimally invasive laparoscopic resection. Besides the restricted view, a major issue in laparoscopic liver resection is the precise localization of the vessels to be divided. To navigate the surgeon to these vessels, pre-operative imaging data can hardly be used due to intra-operative organ deformations caused by appliance of carbon dioxide pneumoperitoneum and respiratory motion.

Therefore, we propose to use an optically tracked mobile C-arm providing cone-beam computed tomography imaging capability intra-operatively. After patient positioning, port placement, and carbon dioxide insufflation, the liver vessels are contrasted and a 3D volume is reconstructed during patient exhalation. Without any further need for patient registration, the volume can be directly augmented on the live laparoscope video. This augmentation provides the surgeon with essential aid in the localization of veins, arteries, and bile ducts to be divided or sealed.

Current research focuses on the intra-operative use and tracking of mobile C-arms as well as laparoscopic ultrasound, augmented visualization on the laparoscope's view, and methods to synchronize respiratory motion.
Intra-operative Beta Probe Surface Imaging and Navigation for Optimal Tumor Resection

Intra-operative Beta Probe Surface Imaging and Navigation for Optimal Tumor Resection

In minimally invasive tumor resection, the goal is to perform a minimal but complete removal of cancerous cells. In the last decades interventional beta probes supported the detection of remaining tumor cells. However, scanning the patient with an intraoperative probe and applying the treatment are not done simultaneously. The main contribution of this work is to extend the one dimensional signal of a nuclear probe to a four dimensional signal including the spatial information of the distal end of the probe. This signal can be then used to guide the surgeon in the resection of residual tissue and thus increase its spatial accuracy while allowing minimal impact on the patient.
Automatic thrombus segmentation in in vivo micoscopic video sequences under low contrast and highly dynamic conditions

Automatic thrombus segmentation in in vivo micoscopic video sequences under low contrast and highly dynamic conditions

The Bloodomics EU project aims are to identify the genetic risks factors of coronary heart diseases.
One of the most common methods is to study the thrombus formation in the dorsal aorta of mutant Zebrafish larvae. The developing thrombus is imaged in vivo through a microscope/camera setup. The derived time to attachment, growth speed, and time to occlusion permits the characterization of the thrombus formation.
However, this step presently remains manual. Our objective is to provide the geneticists in the Wellcome Trust Sanger Institute with an image processing tool to automatically detect and segment the growing thrombus. This will significantly speed up and improve the precision of this current analysis.
