SPECT is primarily used in the clinic for noninvasive cardiac myocardial perfusion imaging. However, sensitivity is impaired due to the need for collimation in SPECT. New second generation systems including those with multi-pinhole collimation has shown high sensitive acquisitions. This has enabled faster or lower dose “stress-first” acquisitions, but not both. Here a third generation dedicated Cardiac...
In this paper, using Defrise Phantoms, we present our investigations of the axial limitations of an analytical cone-beam reconstruction algorithm (FDK), and the iterative ordered-subset transmission reconstruction (OSTR) iterative algorithm, for an axially extended version of the Philips Brightview XCT cone beam CT (CBCT) geometry. Simulations were preformed for head size and body size Defrise Phantoms...
