Image-Guided Radiotherapy For Internal Tumor Boost

摘要

An image-guided radiotherapy system for tumor treatment featuring obtaining a three-dimensional visualized tumor image, identifying the boundary of the tumor, and designating and applying a boosted radiation dose of treatment for a boost region within the tumor boundary. A predetermined safety region is between the boosted region and the tumor boundary with a predetermined minimum distance between the boosted region boundary and tumor boundary.

主权项

1. An apparatus for treatment of a tumor, wherein the apparatus comprises:
(a) an imaging means for obtaining a three-dimensional visualized tumor image (100) to identify a tumor (110); (b) one or more processors configured to delimit a tumor boundary (115) of the imaged tumor (110), and configured to designate a boosted region (120) within the tumor boundary, wherein a predetermined safety region (125) is between the boosted region and the tumor boundary (115) with a predetermined minimum distance (126) between the boosted region boundary and tumor boundary, wherein the boosted region (120) is more than 20% of the volume within the tumor boundary (115); and (c) a radiation means configured to apply a boosted radiation dose of treatment within the boosted region (120) within the tumor boundary (115).
