Embodiment Construction

[0017] The technical details set forth in the following description will enable one skilled in the art to implement one or more embodiments of the present disclosure.

[0018] figure 1 is a schematic diagram illustrating an example process flow 100 for radiation therapy. Example process 100 may include one or more operations, functions, or actions illustrated by one or more blocks. Various blocks may be combined into fewer blocks, divided into additional blocks and / or deleted based on the desired implementation. exist figure 1 In the example in , radiation therapy typically includes various stages, such as imaging system performing image data acquisition for the patient (see 110); radiation treatment planning system (see 130) generating an appropriate treatment plan for the patient (see 156); and treatment delivery The system (see 160) delivers therapy according to the therapy plan.

[0019] In more detail, in figure 1 At 110 , image data acquisition may be performed u...

Abstract

An example approach for adaptive radiation therapy planning using a deep learning engine is provided. An example method may include obtaining therapy image data associated with a first imaging modality. The treatment image data may be acquired during a treatment session of the patient. Additionally, planning image data associated with a second imaging modality may be acquired prior to the treatment session to generate a treatment plan for the patient. The method may further include transforming the treatment image data associated with the first imaging modality to generate a treatment image data associated with the second imaging modality in response to determining that an update to the treatment plan is required. The transformed image data. The method may also include processing the transformed image data using the deep learning engine to generate output data to update the treatment plan.

Description

technical field [0001] The present disclosure generally relates to methods and systems for adaptive radiation therapy planning using deep learning engines. Background technique [0002] 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. [0003] Radiation therapy is an important part of treatment for reducing or eliminating unwanted tumors from patients. Unfortunately, applied radiation by itself will not distinguish an undesired tumor from any proximal healthy structures, such as organs and the like. This requires careful administration to limit the radiation to the tumor (ie, the target). Ideally, the goal is to deliver lethal or disabling radiation doses to the tumor while maintaining acceptable dose levels in proximal healthy structures. However, conventional radiation therapy planning and / or adaptive radiation therapy plannin...
