摘要: Abstract The performance of a novel type animal PET camera, the quad High-Density Avalanche Chamber (HIDAC) was assessed for non-rotating 16-module system. Spatial resolution 1.0 mm, and invariant within standard deviation ⩽5%. Absolute sensitivity 0.95%, scatter-background corrected 0.75%. count rate capability linear at typical activities used in imaging, with 20% loss 11.5 MBq. camera demonstrates small regions radiotracer uptake excellent detail mouse.
