Calibration and evaluation of a motion measurement system for PET imaging studies

Given the high safety requirement when moving a 15-20 kg weight over a human head with a robot, we plan to Positron Emission Tomography (PET) relies on the injection utilize both mechanical and optical measurement systems, of a radioactive tracer, which is then preferentially and possibly also inertial sensing, to attain redundant sensing absorbed by specific tissues (based on the choice of tracer). of the relative motion between the subject's head and The absorbed tracer emits positrons that react with nearby the PET imaging ring. This paper addresses the design, electrons, creating a pair of annihilation (gamma) photons calibration, and evaluation of a mechanical sensing system, that travel in opposite directions and are detected by the consisting of six string encoders connecting the PET detector PET imaging ring. Higher sensitivity can be achieved by to a safety helmet attached to the subject's head.
