Apparatus And Method For Scanning A Patient and Detecting Patient Movement

摘要

Patient scanning apparatus and a method is provided in which the patient movement is detected during a first and a second scan type. If the movement is detected as passing a threshold then remedial action may be taken which may include a re-scan. This confers the advantage of ensuring rapid patient throughput as problems with a scan are detected at an early stage. The movement of the patient relative to the patient support may be detected using a plurality of piezoelectric sensors or pneumatic sensors mounted on the patient support. The invention may be used in PET-CT imaging where the first scan is a CT scan and the second scan is a PET scan.
