Control of the positioning of a scanning region of a medical imaging system

A medical imaging system for recording of a region of interest of an examination object, the medical imaging system comprising:

• a depth-image-data sensor configured to capture depth image data of the examination object;
• a 2D camera configured to create 2D image data of at least one 2D image of the examination object;
• a registration unit configured to register the 2D image data to the depth image data of the examination object at least in some regions;
• a determining unit configured to determine first start and stop lines representing a region of the examination object to be scanned by the medical imaging system;
• and
• an avatar-creating unit configured to create a three-dimensional avatar of the examination object on the basis of the depth image data registered to the 2D image data of the examination object;
• an image-display unit to display at least one of the 2D image and the avatar of the examination object;
• a limit-positioning-capturing unit configured to capture at least one limit position of the scanning region by using at least one of the 2D image and the avatar displayed;
• and
• a limit-contour-line-determining unit configured to determine a limit contour line of the scanning region representing a corrected scanning region extending through the limit position on the basis of the depth image data and the limit position of the scanning region in the 2D image, said limit contour line being displayed superimposed on the 2D image in the image-display unit.
