Embodiment Construction

[0025] The present disclosure generally relates to patient-specific radiation therapy plan validation and quality assurance systems, devices, and methods. In the description below, certain terms are used for convenience only and not for limitation. Unless otherwise stated herein, the expressions "a", "an" and "the" are not limited to denoting one element, but should be read as "at least one".

[0026] A system or method of the present disclosure may include acquiring or receiving one or more sets of radiotherapy medical images of at least one region (eg, cranial region and / or thoracic region) of a living patient. The radiotherapy medical image may include one or more of x-ray computed tomography (CT) images, magnetic resonance images (MRI), positron emission tomography (PET) images, etc., or any combination thereof. The images can be acquired in accordance with a treatment planning system (TPS) for determining areas to be irradiated and areas to be excluded from irradiation. ...

Abstract

A radiotherapy treatment verification and quality assurance method may include receiving at least one set of first medical images of at least a portion of a patient. A three-dimensional model of the portion of the patient may be created based on the at least one set of first medical images. At least one dosimeter may be inserted into at least a portion of the model. The dosimeter is configured to measure exposure to radiation. The model may be irradiated in accordance with a radiotherapy treatment plan created by a treatment planning system. A readout of the model may be taken or performed to measure in three-dimensions a delivered radiation doses distribution.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 61 / 876,269, filed September 11, 2013, entitled "Methods for Treatment Validation and Quality Assurance of Patient-Specific Radiation Therapy," the contents of which are hereby incorporated by reference in their entirety. Background technique [0003] Radiation therapy or radiotherapy (RT) is a common treatment modality for treating cancer. The goal of the radiation therapy process is to expose the tumor to a sufficient dose of radiation to destroy all cancer cells. Radiation doses are usually close to levels tolerated by normal body tissue. Therefore, it is necessary to determine dose levels at different parts of the irradiated body with high precision and accuracy. [0004] Recent advances in radiology and bioimaging imaging have improved the diagnosis and treatment of cancer. For radiation therapy, these advances make it possible to precisely de...
