Abstract
In-situ visualization in medical augmented reality (AR) enables the registered view of virtual data such as a 3D CT scan, with a video view of the real anatomy of a patient. Data can be aligned with the required accuracy such that surgeons do not have to analyze data on an external monitor in the operating room. Instead, surgeons get a direct view onto and ”into” the patient. Mental registration of medical imagery with the operation site is not necessary anymore. Augmenting medical images and virtual surgical instruments within the body provides the most intuitive way to understand the patient’s anatomy within the region of interest. This allows for the development of completely new generations of surgical navigation systems. CAMP is one of the strongest research centers for medical AR world-wide, featuring the world’s most accurate video-see-through AR system based on a head-mounted-display. Also, CAMP has developed the world’s first AR-enabled C-arm, CamC, which has already been tested in clinical trials in Munich.Contact Person and Group Coordination

NARVIS - navigated augmented reality visualization systemAdvanced visualization is getting increasingly important for the operation room of the future. The increasing number of available medical images must be presented to surgery team in new ways in order to support them rather than overloading with more information. In our project NARVIS we integrate an HMD-based (head mounted display) AR system into the operation room for 3D in situ visualization of computed tomography (CT) images. The final system aims at spinal surgery. The work is in close collaboration with our project partners “Klinikum für Unfallchirgie” at LMU, A.R.T. Weilheim, and Siemens Corporate Research in Princeton. The project is funded by Bayerische Forschungsstiftung. |

Automatic Progression Tracking of Skin LesionsThe 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. |

Augmented Reality Magic Mirror using the KinectThe Microsoft Kinect provides a color and a depth image. Using OpenNI? and PrimeSense? NITE we can get the skeleton of a person standing in front of the Kinect in real-time. We register a CT dataset to this skeleton and do an Augmented Reality overlay of the CT and the person. Using context and focus visualization we only show the CT through a virtual window, while still showing the person. The Kinect is positioned next to a big screen. When standing in front of the system, the system acts like a magic mirror that allows seeing inside yourself. Such a system can be used for educational purposes to teach anatomy. The system is currently a prototype. It does not show the CT of the person in front of the monitor, but a CT of another person. We use the Visible Korean Human dataset that has been provided to us by Prof. Min Suk Chung. |

ARAV Augmented Reality Aided VertebroplastyIn today’s ORs more and more operations are performed employing minimally invasive procedures. Surgical instruments are inserted through a tiny cut on the patient’s skin, the port to the inside of the patient. In some cases endoscope cameras record video images of the operation site that are presented on a monitor. As a consequence of this technique, the surgeon’s field of view is divided into several work spaces, the monitor, the patient and information of medical imaging data presented on a third station. The missing direct view on the workspace complicates intuitive control of surgical tools. In contrast to open surgery the physician has to collect information from several fields of view at the same time and fuse information mentally to create a complete model of his working space, the operation site. The minimally invasive intervention vertebroplasty was determined as a suitable medical application to bring an Head Mounted Display (HMD) into the OR for augmentation of surgical instruments and medical imaging data. In-situ visualization with an HMD presents all available imaging data and navigational information in one field of view. The objective of vertebroplasty is the insertion of cement into weak and brittle vertebrae through a trocar for stabilization. In this case the view on the inside of the patient is not provided by an endoscope camera. However, since the operation is performed under a CT scanner, imaging data is permanently updated to check position of the trocar and amount of inserted cement. Imaging data is presented on a monitor and has to be mapped mentally by the surgeon on the real operation site. |

Improving Depth Perception and Perception of Layout for In-Situ Visualization in Medical Augmented RealityIn-situ visualization in medical augmented reality (AR) using for instance a video see-through head mounted display (HMD) and an optical tracking system enables the stereoscopic view on visualized CT data registered with the real anatomy of a patient. Data can aligned with the required accuracy and the surgeons do not have to analyze data on an external monitor or images attached to the wall somewhere in the operating room. Thanks to a medical AR system like mentioned before, surgeons get a direct view onto and also ”into” the patient. Mental registration of medical imagery with the operation site is not necessary anymore. In addition surgical instruments can be augmented inside the human body. Bringing medical imagery and surgical instruments in the same field of action provides the most intuitive way to understand the patient’s anatomy within the region of interest and allows for the development of completely new generations of surgical navigation systems.Unfortunately, this method of presenting medical data suffers from a serious lack. Virtual imagery, such as a volume rendered spinal column, can only be displayed superimposed on real objects. If virtual entities of the scene are expected behind real ones, like the virtual spinal column beneath the real skin surface, this problem implicates incorrect perception of the viewed objects respective their distance to the observer. The strong visual depth cue interposition is responsible for misleading depth perception. This project aims at the development and evaluation of methods to improve depth perception for in-situ visualization in medical AR. Its intention is to provide an extended view onto the human body that allows an intuitive localization of visualized bones and tissue. |

Virtual Mirror: Interaction Paradigm for Augmented Reality ApplicationsAugmented Reality offers a higher degree of freedom for the programmer than classical visualization of volume data on a screen. The existing paradigms for interaction with 3D objects are not satisfactory for particular applications since the majority of them rotate and move the object of interest. The classic manipulation of virtual objects cannot be used while keeping real and virtual spaces in alignment within an AR environment. This project introduces a simple and efficient interaction paradigm allowing the users to interact with 3D objects and visualize them from arbitrary viewpoints without disturbing the in-situ visualization, or requiring the user to change the viewpoint. We present a virtual, tangible mirror as a new paradigm for interaction with 3D models. The concept borrows its visualization paradigm in some sense from methodology used by dentists to examine the oral cavity without constantly changing their own viewpoint or moving the patients head. The virtual mirror improves the understanding of complex structures, enables completely new concepts to support navigational aid for different tasks and provides the user with intuitive views on physically restricted areas. |

Intra-operative Human Computer Interaction and Usability EvaluationsComputerized 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. |

Advanced imaging in Head Mounted Displays (HMD) for Patients with Age-Related Macular DegenerationAge-related macular degeneration (AMD) is one of the leading causes of low vision worldwide without a medical solution. Nevertheless, enhancement of people's vision by means of mediated reality is conceivable. This project presents a head-mounted magnification system to enhance visual perception acquired with peripheral vision. A hybrid magnification technique is adjusted and implemented on a head-mounted display. Moreover, a system for modeling and correcting distorted vision is proposed. The system obtains a correction model by means of a deformable grid. To evaluate the system, a method for simulating distorted vision is applied. By superimposing the model on OCT macular images, it is suitable to identify macular features, which could help on the development of an automatic correction method. |

Research Group: Assessment and Training of Medical Expert with Objective Standards (ATMEOS)In highly dynamic and complex high-risk domains - such as surgery - systematic training in the relevant skills is the basis for safe and high-quality performance. Traditionally, assessment and training in surgery traditionally concentrated upon proficiency and acquisition of surgeons' technical skills. As the fundamental impact of non-technical skills - such as communication and coordination - is increasingly acknowledged for safe delivery of surgeries comprehensive training approaches are missing. The overall aim of the project is to investigate a novel learning environment for the assessment and training of both technical and non-technical skills of entire multidisciplinary operating room (OR) teams. |

Augmented Reality Supported Patient Education and ConsultationThe project Augmented Reality Supported Patient Education and Consultation (Augmented Reality unterstützte Operationsaufklärung) aims at developing Augmented Reality (AR) supported communication tools for patient education. The development of the targeted systems involves disciplines reaching from image registration, human computer interaction and in-situ visualization to instructional design and perceptual psychology. As a primary clinical application, we determined breast reconstruction in plastic surgery. |

Real-time fusion of ultrasound and gamma probe for navigated localization of malignancyIntra-operative localization of non-superficial cancerous lesions in non-hollow organs like liver, kidney, etc is currently facilitated by intra-operative ultrasound (IOUS) and palpation. This yields a high rate of false positives due to benign abnormal regions and thus unnecessary resections with increased complications and morbidity. In this project we integrate functional nuclear information from gamma probes with IOUS, to provide a synchronized, real-time visualization that facilitates the detection of active tumors and metastases intra-operatively. The bet of this project is that the inclusion of an advanced, augmented visualization provides more reliability and confidence on classifying lesions prior to the resection. |

Freehand SPECT for Sentinel Lymph Node LocalizationNuclear 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. |
 |
Camera Augmented Mobile C-arm ( CamC )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. |

3D user interfaces for medical interventionsThis work group aims at practical user interfaces for 3D imaging data in surgery and medical interventions. The usual monitor based visualization and mouse based interaction with 3D data will not present acceptable solutions. Here we study the use of head mounted displays and advanced interaction techniques as alternative solutions. Different issues such as depth perception in augmented reality environment and optimal data representation for a smooth and efficient integration into the surgical workflow are the focus of our research activities. Furthermore appropriate ways of interaction within the surgical environment are investigated. |

Magneto-Optic Tracking of a Flexible Laparoscopic Ultrasound TransducerIn abdominal surgery, a laparoscopic ultrasound transducer is commonly used to detect lesions such as metastases. The determination and visualization of position and orientation of its flexible tip in relation to the patient or other surgical instruments can be of much help to (novice) surgeons utilizing the transducer intraoperatively. This difficult subject has recently been paid attention to by the scientific community. Electromagnetic tracking systems can be applied to track the flexible tip. However, the magnetic field can be distorted by ferromagnetic material.We present a new method based on optical tracking of the laparoscope and magneto-optic tracking of the transducer, which is able to automatically detect and correct field distortions. This is used for a smooth augmentation of the B-scan images of the transducer directly on the camera images in real time. |

Laparoscope Augmentation for Minimally Invasive Liver ResectionIn 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 ResectionIn 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. |

Computer-Aided Ophthalmic ProceduresIn the current workflow of opthamologic surgeries, the surgeon observes the scene in an indirect way through a microscope while performing the surgery with the necessary high handling precision. During membrane peeling, for example, the surgeon has to grasp an anatomical layer of only 10 μm off the retina without damaging it. However, under this limited microscopic view, it becomes very challenging to infer the distance of the surgical instrument to the retina. Issues such as lens distortion, high level of blurriness and lack of haptic feedback complicate the task further. Recently, an intraoperative version of the Optical Coherence Tomography (OCT) was introduced, which provides the 3D information along a scanning line. On the one hand, this modality provides depth information during the surgery. On the other hand, the device has to be manually positioned to the region of interest which further complicates the current workflow of the surgeon (who already has to manipulate the surgical tool, the handheld light source and the microscope). The main goal of the project is support the surgeon in the current workflow and provide additional information during the surgery via advanced computer vision, visualization and augmented reality algorithms. |
