Adaptive Detector Positioning for a Room PET System

Investigating human brain function in response to environmental stimuli requires freely moving humans without attached instrumentation. The RoomPET concept provides a feasible solution for human brain imaging. A RoomPET system is a room that contains an optical head tracking system and PET detectors that move to keep the head in the PET detector field-of-view. As a proof of principle, a small box-size prototype was built to demonstrate feasibility of RoomPET with gantry mechanics, tracking capabilities, and control systems.
