A Cardiac SPECT System with Multiple Collimated Detectors Rotating in an Elliptical Orbit
The cardiac SPECT is a good study because of the large clinical demand and the need for improved image quality. SPECT imaging usually suffers from poor spatial resolution and high statistical noise due to patient radiation safety concerns. Based on an emission imaging device shaped as an arc in the form of a part of an ellipse with multiple collimated detector columns, a new cardiac SPECT system in an elliptical orbit (EO-SPECT) is proposed to improve the geometric efficiency and the spatial resolution.
