title = "Design and performance of a new SPECT detector for multimodality small animal imaging platforms",
abstract = "A new detector for single photon emission computed tomography (SPECT) has been developed for the Siemens microCAT{\textregistered} II and Inveon Multimodality preclinical imaging systems. The detector provides an active imaging area of 15 cm × 15 cm. We review the design of this new SPECT detector and present some key performance characteristics. Integral and differential uniformity were 3.7% and 3.0%, respectively. Mean energy resolution for 99mTc (140 keV) was 12.5%. Sensitivity as high as 1400 cps/MBq was measured for 99mTc on a dual-detector system, and a spatial resolution of 0.7 mm (FWHM) was obtained using 0.5 mm single pinhole collimators. Additionally, we present data from representative preclinical SPECT studies acquired with single and multi-pinhole collimators and multiple isotopes. Reconstructed images demonstrate that this detector is capable of high-resolution SPECT for multimodality small animal imaging.",
