THREE DIMENSIONAL LOCALIZATION OF A MOVING TARGET FOR ADAPTIVE RADIATION THERAPY

摘要

The present disclosure relates to systems, methods, and computer-readable storage media for segmenting medical image. Embodiments of the present disclosure may locate a target in a three-dimensional (3D) volume. For example, an image acquisition device may provide a 3D medical image containing a region of interest of the target. A processor may then extract a plurality of two-dimensional (2D) slices from the 3D image. The processor may also determine a 2D patch for each 2D slice, wherein the 2D patch corresponds to an area of the 2D slice associated with the target. The processor may also convert the 2D patch to an adaptive filter model for determining a location of the region of interest.

1. A method, implemented by a processor, for locating a target in a three-dimensional (3D) volume, the method comprising:
receiving, from an image acquisition device, a 3D medical image containing a region of interest of the target; extracting, by the processor, a plurality of two-dimensional (2D) slices from the 3D image; determining, by the processor, a 2D patch for each 2D slice, wherein the 2D patch corresponds to an area of the 2D slice associated with the target; and converting, by the processor, the 2D patch to an adaptive filter model for determining a location of the region of interest.
