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 determine a primary plane of motion of the anatomical region of interest and determine a plurality of 2D slices parallel to the primary plane. The plurality of 2D slices may define a 3D volume substantially enclosing the anatomical region of interest. The processor device may also be configured to control the image acquisition device to acquire a plurality of 2D images based on the plurality of 2D slices and determine a motion of the anatomical region of interest based on at least a subset of the acquired plurality of 2D images. The processor device may be further configured to control radiation delivery based on the determined motion.

Claim (Index 34):
A radiotherapy system, comprising:\n an image acquisition device configured to acquire Magnetic Resonance Imaging (MRI) images of an anatomical region of interest of a patient; a radiotherapy device including a linear accelerator (LINAC) and configured to deliver a dose of radiation to the anatomical region of interest based on the images of the anatomical region of interest; a processor device configured to:\n determine a primary plane of motion of the anatomical region of interest, the primary plane of motion including a sagittal plane, a coronal plane, or a transverse plane; \n determine a plurality of two-dimensional (2D) slices parallel to the primary plane, the plurality of 2D slices defining:\n a three-dimensional (3D) volume substantially enclosing the anatomical region of interest; and \n a plurality of spatial locations relative to the anatomical region of interest; \n \n control the image acquisition device to acquire a series of 2D images by repeatedly sweeping across the plurality of 2D slices, wherein each 2D image within the series corresponds to one of the plurality of 2D slices; \n construct a four-dimensional (4D) image of the 3D volume based on at least a subset of the series of 2D images, including:\n receive a first 2D image within the series that corresponds to a first 2D slice; \n insert the first 2D image into the 4D image; \n receive a second 2D image within the series that also corresponds to the first 2D slice; and \n replace the first 2D image in the 4D image with the second 2D image; \n \n determine a motion of the anatomical region of interest based on a comparison between 3D snapshots of the 4D image at different times during a radiotherapy session, wherein the motion of the anatomical region of interest includes at least one of position change or deformation; and \n control radiation delivery based on the determined motion, including at least one of:\n control a gating of a radiation beam; \n control a modification of a multi-leaf collimator (MLC); or \n control a movement of a patient supporting system.
