Abstract: A method is provided of obtaining body depth information for a patient who is lying on patient support. A patient support depth map of the upper surface of the patient support is obtained without the patient as well as an image and patient depth map of the patient on the patient support. Landmark body positions of the patient are extracted from the image so that points in a region of interest can be mapped to points of a template, using the identified landmark body positions. A body thickness is obtained for said points using the template, the depth value for the respective point and the patient support depth value for the respective point.

Abstract: An imaging system is for capturing images of a patient during a medical scan. A set of one or more cameras captures images of the patient such that, after applying distortion and perspective correction steps, pixel rows correspond to locations along an axis parallel to the direction of patient support movement and pixel columns correspond to locations along an axis perpendicular to the patient support. Patient motion of interest can then be identified based on image movements in the pixel column direction between sequential captured images. A measure of patient motion can then be derived.
