Abstract

This work evaluates the system performance of a dynamic cardiac SPECT (DC-SPECT) system using Monte Carlo simulations. We assessed the system’s sensitivity across the field of view (FOV) and evaluated spatial resolution using reconstructed images of a Derenzo phantom, a Jaszczak phantom, and an XCAT cardiac phantom. Results show that the system achieves a resolution of 5.5 mm for hot rods without background, and 6.0 mm for cold rods with warm background. The sensitivity ranges from 5 to 9 times greater than conventional dual-head SPECT over a 15 cm diameter spherical FOV. This study demonstrates that the current design of DC-SPECT has the potential to support effective cardiac imaging.
