This stationary SPECT system is inexpensive to build, small, and able to acquire true dynamic SPECT data. Stationary cardiac SPECT systems with multipinhole technology already exist. The proposed approach is to replace the multipinhole collimators with the originally designed multidivergent\u2010beam collimators. The motivation for replacing the pinhole technology by divergent\u2010beam technology is based on the following facts. The resolution\/sensitivity trade\u2010off for the pinhole is excellent (good resolution and good sensitivity) only in small object (e.g., small animal) imaging when it operates in the image magnifying mode. However, in large object (e.g., human) imaging, the resolution\/sensitivity trade\u2010off is poor (poor resolution and poor sensitivity) when the pinhole operates in the image reducing mode. In a stationary system, the number of angular views is limited; thus, image reduction is necessary to obtain more view angles. In this image reducing situation, divergent\u2010beam collimation is able to provide better resolution and detection sensitivity than pinhole collimation. Computer simulations are carried out to verified the claims.<\/jats:p>","DOI":"10.1118\/1.3134245","type":"journal-article","created":{"date-parts":[[2009,6,26]],"date-time":"2009-06-26T22:24:03Z","timestamp":1246055043000},"page":"2860-2869","source":"Crossref","is-referenced-by-count":6,"title":["Multidivergent\u2010beam stationary cardiac SPECT"],"prefix":"10.1002","volume":"36","author":[{"given":"Gengsheng L.","family":"Zeng","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew M.","family":"Stevens","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,6,9]]},"reference":[{"issue":"1","key":"e_1_2_7_2_1","first-page":"189P","article-title":"D\u2010SPECT: A new solid state camera for high speed molecular imaging","volume":"47","author":"Patton J.
