Embodiment Construction

[0040] The method, device, and computer equipment for locating radiotherapy quality control measurement points proposed by the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become apparent from the following description and claims. It should be noted that, the accompanying drawings are all in a very simplified form and in inaccurate scales, and are only used to facilitate and clearly assist the purpose of explaining the embodiments of the present invention.

[0041] The inventor's research found that the quality control (QA) of radiotherapy planning is an important link in radiotherapy, and the commonly used QA methods include the comparison of point dose or surface dose measurement and calculation. When measuring the point dose, in order to reduce the measurement error, it is necessary to select a position with a smaller dose distributi...

Abstract

The invention provides a radiotherapy quality control measuring point positioning method and computer equipment. The method comprises the following steps: acquiring an image of a verification die body; dividing the image of the verification die body into a plurality of sub-images; calculating dose distribution on the verification die body based on a to-be-verified radiotherapy plan and the image of the verification die body; determining the sub-image of which the dose distribution meets a preset requirement as a target sub-image; and determining the position of the center point of the target sub-image as a radiotherapy quality control measuring point. Through the above positioning method, automatic point finding can be realized, the position with the minimum dose distribution gradient is obtained to serve as the quality control measuring point, measurement errors are reduced, a radiotherapy physicist is assisted in rapidly finding the appropriate position of the radiotherapy quality control measuring point, and the workload of the radiotherapy physicist for point dose quality control is reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a method and computer equipment for locating radiotherapy quality control measurement points. Background technique [0002] Radiation therapy (RT), referred to as radiotherapy, is one of the most important local treatments in the treatment of malignant tumors. Nearly 70% of cancer patients require radiation therapy as part of their cancer treatment. At present, the role and status of radiotherapy in tumor treatment has become increasingly prominent, and radiotherapy has become the main means of treating malignant tumors. A radiotherapy machine is a large-scale medical device used for cancer radiotherapy. It directly irradiates the tumor in the patient's body by generating a radiation beam, so as to achieve the purpose of eliminating or reducing the tumor. [0003] Most of the radiotherapy machines cannot image the treatment site in real time at the same time of treatm...
