Performance characteristics of a small animal PET camera for molecular imaging

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