New Hardware Solutions for Cardiac SPECT Imaging.

Over the past decade, there has been intense interest in the modernization of scanners for cardiac SPECT imaging, with major changes in the design and functionality of hardware and software. This article aims at concisely reviewing recent developments in the field of detector materials, collimators, scanner configuration, and data acquisition strategies, as well as the new software reconstruction techniques typically associated with the new hardware. Since the new equipment and techniques can be employed either to reduce study acquisition time or to decrease radiation dose to the patient, the trade-off between these 2 desirable outcomes is also explored.
