Abstract
A portable, cost-effective system has been designed and implemented to perform noninvasive, cardiac blood-pool imaging. A list mode, digital data-collection unit is interfaced to an existing portable scintillation camera for the bedside evaluation of acutely ill patients. List mode data is reformatted off-line and then processed in a central nuclear medicine facility. This portable system is a more flexible and less expensive alternative to available portable, digital data-acquisition equipment and gamma camera combinations.
