Abstract

Example methods and systems are provided for performing radiation dose estimation on a target subject. In one example, radiation dose estimation may include obtaining projection image data acquired using an imaging system, generating partially reconstructed volumetric image data based on the projection image data, and generating partitions of the projection image data. Partially reconstructed volumetric image data may be associated with the first region of the total radiation field. The subregions may be associated with a second region of the total radiation field which is located in front of the first region from the direction of the radiation source. Radiation dose data for the target object may be estimated based on partially reconstructed volume image data associated with the first region and the partition associated with the second region.

Description

Background technique [0001] Unless otherwise indicated herein, the approaches described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section. [0002] Radiation therapy is an important part of treatment for reducing or eliminating unwanted tumors from patients. Unfortunately, the applied radiation does not inherently discriminate between unwanted tumors and any adjacent healthy structures (such as organs, etc.). This requires careful administration to limit radiation to the tumor (ie target). Ideally, the goal is to deliver lethal or curative radiation doses to the tumor while maintaining acceptable dose levels in proximal healthy structures. In practice, however, there are various challenges associated with radiation dose estimation to deliver a radiation dose that achieves this goal. Contents of the invention [0003] According to examples of the present disclosure, methods and systems for ...
