Picture of me

Dr. Tobias Blum
I have been with the Chair for Computer Aided Medical Procedures & Augmented Reality as PhD student and research assistant between 2007 and 2013.

As of March 2013 I moved to Ferchau Engineering and I am currently working for BMW Research and Technology on head-up displays and navigation systems.

Research projects

mirracle

Using the metaphor of a magic mirror, mirracle shows an augmented reality overlay of a CT dataset onto a user standing in front of a big screen. We track the person using Microsoft Kinect. The system could be used for anatomy education or patient consulting. See http://www.mirracle.de for more information.

Surgical Workflow Analysis in Laparoscopy for Monitoring and Documentation

Surgical Workflow Analysis in Laparoscopy for Monitoring and Documentation

Surgical workflow recovery is a crucial step towards the development of intelligent support systems in surgical environments. The objective of the project is to create a system which is able to recognize automatically the current steps of a surgical laparoscopic procedure using a set of signals recorded from the OR. The project adresses several issues such as the simultaneous recordings of various signals within the OR, the design of methods and algorithms for processing and interpreting the information, and finally the development of a convenient user interface to display context sensitive information inside the OR. The current clinical focus is on laparoscopic cholecystectomies but the concepts developed in the project also apply to laparoscopic surgeries of other kinds.
Analysis and Modeling of Actions for Advanced Medical Training Systems

Analysis and Modeling of Actions for Advanced Medical Training Systems

Providing feedback to trainees is one of the most important issues to support learning. This project researches how to give quantitative and visual feedback on the performance of a student when training on simulators or phantoms. Statistical analysis and probabilistic models are used to compare the performance of students and experts. Augmented Reality and video is used to give visual feedback like a synchronized replay of the student’s and the expert’s performance.
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.
