1. An apparatus for monitoring a subject during a medical imaging procedure using a medical imaging device, wherein the imaging device comprises a support for supporting the subject and moving the subject during the imaging procedure, the apparatus comprising:
a memory that stores a plurality of instructions; and
processor circuitry that couples to the memory and is configured to execute the plurality of instructions to:
provide monitoring images of the subject comprising a first monitoring image and a second monitoring image of the subject, wherein the first monitoring image is acquired at a first support position and the second monitoring image is acquired at a second support position,
provide a first monitoring position and shape being indicative of a position and shape of a region of interest in the first monitoring image,
provide support position data being indicative of the second support position,
provide a position map for mapping calibration support positions with calibration monitoring positions of a calibration procedure during which calibration monitoring images are acquired at different calibration support positions with a calibration object supported by the support, wherein a calibration monitoring position is indicative of a position of the calibration object in a calibration monitoring image at a respective calibration support position indicated by calibration support position data, and
determine a position and shape of the region of interest in the second monitoring image based on the first monitoring position and shape, the support position data, and the position map, wherein a change in the shape of the region of interest of the subject is monitored based on the second monitoring image and the position of the region of interest in the second monitoring image.
