Pre-clinical and Clinical Evaluation of High Resolution, Mobile Gamma Camera and Positron Imaging Devices
Annual rept. 13 May 2008-20 Sep 2009
FLORIDA UNIV GAINESVILLE
Pagination or Media Count:
The overall objective of this project is to design, build and evaluate a compact and mobile gamma and positron imaging camera. This imaging device has several advantages over conventional systems 1 greater flexibility in positioning with respect to the target organ for improved spatial resolution and sensitivity, 2 the ability to image patients who cannot be transported to a radiology suite, 3 the potential for improved cost effectiveness for organ-specific imaging tasks compared with larger, general purpose imaging systems. Over the past year, the following tasks have been completed 1 obtained human subjects research approval by University of Florida Institutional Review Board and U.S. Army Medical Research and Materiel Command USAMRMC, Office of Research Protections ORP, Human Research Protection Office HRPO, 2 completed study on imaging performance using a cardiac thorax phantom including simulated perfusion defects, 3 advanced the development of a pinhole collimator for the mobile imaging system including final design specifications, fabrication of the collimator, and initial experimental performance evaluation.
