Since April 2009 I am studying as a Ph.D student in the Interactive Graphics Systems Group (GRIS)
of the Computer Science Department at TU Darmstadt Germany. My area of interest
is Medical Image processing including super-resolution, segmentation and simulation.
Medical Imaging is the synthesis of Computer Graphics, Image Processing, Medicine, and Physics.
Optimal catheter selection for coronary angiography In this project we have investigated how an optimal catheter can be selected for a patient during coronary angiography. Coronary angiography is performed to investigate the presence of any blockage in the coronary arteries. Due to the anatomical variation of aorta and coronary arteries in different humans, one common catheter cannot be used for all patients. The cardiologists test different catheters for a patient and select the best catheter according to the patient's anatomy. we propose a computer aided catheter selection procedure where the cardiologist (especially those with less experience) already gets the recommendation about the optimal catheter for the patient prior to the intervention. Details Super-resolution reconstruction of cardiac image data Our work on super-resolution in 3D images gives solution to the problem of low-resolution in CT and MR cardiac images. We estimate uniform resolution of 1.5 mm in all directions from an initial resolution of 1.5 x 1.5 x 8 mm3. In spite of the resolution difference factor of five in cardiac images, the super-resolution algorithm gives improved resolution and segmentation results in cardiac Images. Details Linux Network Driver for the SICK LMS400 Laser Range Scanner This is a C++ library for communicating with the Laser Scanner LMS400. It allows the users to communicate with the LMS400 through C++ and Matlab. Through this library, users can set different parameters of the Laser Scanner and get output of the related commands. Details Rendering Haptic force feedback using penetration depth computation Computer graphics scenes give us information about shapes and colors of the objects but we cannot feel the scenes. We do not know whether the scene boundaries are soft or hard or whether any object in the scene is heavy or light. Haptic devices are used to incorporate the sense of ‘touch and feel’ into graphics scenes. This project is related to adding the sense of touch and feel in graphics scenes using haptic device.
