Embodiment 1

[0072] The present invention provides a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it can be used to implement a method for judging the validity of radiotherapy image data, and the method for judging the validity of radiotherapy image data Methods include:

[0073] Obtaining a specified layer of the scan image of the radiotherapy object;

[0074] Calculating the photon attenuation ratio after the radiotherapy beam passes through the specified layer of the scanning image;

[0075] obtaining a photon flux map of a specified layer of the scanned image according to the photon attenuation ratio;

[0076] Radiation therapy image data validity is evaluated based on the photon flux map.

[0077] Specifically, please refer to figure 2 , figure 2 It is a flowchart of a method for judging the validity of radiotherapy image data in Embodiment 1 of the present invention. Such as figure 2 As sho...

Embodiment 2

[0121] Please refer to Image 6 , Image 6 It is a flowchart of a dose early warning method in the process of making a radiotherapy plan according to Embodiment 2 of the present invention.

[0122] The difference from Embodiment 1 is that after step S24, if the underlying photon flux map is not less than the preset threshold, at this time, the dose warning method in the radiotherapy planning process further includes:

[0123] Execute step S26: Acquire the radiotherapy virtual model. For example, according to the photon flux map, the photon energy outside the scanned image is further calculated, and the human tissue is virtually outlined.

[0124] Execute step S27: calculate the dose or energy in the radiotherapy virtual model.

[0125] In this embodiment, the radiotherapy virtual model is, for example, a virtual phantom or a virtual radiotherapy object tissue model, which can be calculated according to algorithms well known to those skilled in the art, such as Monte Carlo c...

Abstract

The invention provides a computer readable storage medium, a computer program is stored on the computer readable storage medium, when the computer program is executed by a processor, the computer program can be used for executing a method for judging the validity of radiotherapy image data, and the method for judging the validity of the radiotherapy image data comprises the following steps: obtaining a specified layer of a scanning image of a radiotherapy object; and calculating the photon attenuation proportion of the radiotherapy beam after passing through the specified layer of the scanning image, obtaining a photon flux graph of the specified layer of the scanning image according to the photon attenuation proportion, and evaluating the validity of the radiotherapy image data based on the photon flux graph. The dose flux graph is predicted in real time in the scanning process, whether the CT or MR scanning range is appropriate or not is evaluated, and the problem that scanning needs to be conducted again when the CT or MR scanning range is insufficient is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a computer-readable storage medium, a device for judging the validity of radiotherapy image data, a dose warning device in the process of making a radiotherapy plan, and a computing device. Background technique [0002] For the radiotherapy process, the TPS (Radiotherapy Treatment Planning System, radiotherapy planning system) system calculates the absorbed dose within the patient's image range based on CT (Computed Tomography, computerized tomography) or MR (Magnetic Resonance, magnetic resonance examination) images. When the image scanning range is insufficient, the doctor’s prescription, outline, and TPS dose calculation can be performed normally, but the dose of the radiotherapy target tissue outside the image range is ignored, which may have a large gap with the actual radiotherapy target’s absorbed dose. It may lead to excessively high absorbed dose of tissues and o...
