The Medical Imaging Lab was established in 1991 in the Department
of Biomedical Engineering with funding from a Whitaker
Foundation Development Award. The faculty and students associated with
the lab are interested in the development of new imaging techniques and
advanced applications of existing techniques to solve problems in medicine
and biology. A training program in medical imaging has been established
in the department for both undergraduate and graduate students. To find
out more about this go to the Biomedical Imaging
Selected Research Topics
Imaging the heart and cardiovascular system with magnetic resonance presents
many challenges. Issues such as bio-compatibility, magnetic resonance physics,
patient monitoring, image analysis, computer visualization, and clinical
stress testing must be tackled simultaneously by a diverse research team.
For example, magnetic resonance-compatible pacemakers have been designed
and built; real-time quantitative magnetic resonance stress testing and
fluoroscopy is being performed; and the effect of conduction abnormalities
and pacing in the failing heart is being examined in patients.

Additional Information of Interest.
This mpeg movie shows the combination of a reconstructed LV with the
original imaging data, visualized on the SGI Reality Engine. This shows
how precise mechanical information can be displayed in the original context
of the imaging data. The tags and color are displayed on the calculated
epicardial surface. The color represents radial thickening ( [low] yellow
--> [high] red ).
Homepage provides a manual and tutorial for running the tag strain
analysis application, TEA, which uses the displacement field-fitting approach
to calculate 3D deformations from parallel-tagged MR images. (maintained
by Walter O'Dell at UCSD)
