Patient position monitoring system based on 3D surface acquisition technique

摘要

A method acquires reflectance image content from patient anatomy that is within a volume of an imaging apparatus defined between a radiation source and a detector and generates a surface contour image from the acquired reflectance image content. The generated surface contour image is compared with surface contour image metrics stored for the imaging apparatus and a recommended adjustment to the position of the patient anatomy is reported according to the comparison.
