Abstract:
Systems and methods for managing motions of an anatomical region of interest of a patient during image-guided radiotherapy are disclosed. An exemplary system may include an image acquisition device, a radiotherapy device, and a processor device. The processor device may be configured to control the image acquisition device to acquire at least one 2D image. Each 2D image may include a cross-sectional image of the anatomical region of interest. The processor device may also be configured to perform automatic contouring in each 2D image to extract a set of contour elements segmenting the cross-sectional image of the anatomical region of interest in that 2D image. The processor device may be further configured to match the set of contour elements to a 3D surface image of the anatomical region of interest to determine a motion of the anatomical region of interest and to control radiation delivery based on the determined motion.

Claim (Index 21):
The method of  claim 19 , wherein the the plurality of 2D images include a first 2D image acquired at a first time point and a second 2D image acquired at a second time point, the second time point being more recent than the first time point, and method comprises:\n generating a predicted image by advancing the first 2D image forward in time to the second time point; performing automatic contouring to extract a first set of contour elements segmenting the cross-sectional image of the anatomical region of interest in the predicted image and a second set contour elements segmenting the cross-sectional image of the anatomical region of interest in the second 2D image; and matching the first and second sets of contour elements to the 3D surface image of the anatomical region of interest to determine the motion of the anatomical region of interest.
