Problems solved by technology

However, this also brings certain challenges to physicists in extracting planning parameters and assessing normal tissue exposure. This is because the mechanical structure and software design of the CyberKnife itself are relatively complicated, and the other is because SBRT’s impact on Compared with conventional irradiation, more evaluation parameters are required, and the evaluation criteria for normal tissue tolerance are also more stringent

Embodiment 1

[0070] Please refer to figure 2 , Embodiment 1 of the present invention is: a method for automatically extracting parameters of a CyberKnife treatment plan, comprising the following steps:

[0071] S1: Name the treatment plan file according to the patient's radiotherapy number, course number, split plan number, and split plan number.

[0072] S2: According to the name of the treatment plan file, the corresponding treatment plan file is obtained from the CyberKnife radiotherapy planning system, and the treatment plan file includes an irradiation field path file, a plan file and a plan report file. Among them, the irradiation field path file stores all the irradiation field information, including the number of irradiation fields, the number of irradiation fields, the number of jumps of irradiation field machines, the irradiation dose of irradiation fields, etc. The plan file stores irradiation plan subject information. The plan report file stores summary information on target...

Embodiment 2

[0102] This embodiment is a specific application scenario of the above embodiment, including the following steps:

[0103] 1. Name the plan file;

[0104] In order to facilitate data management, it is first necessary to unify the naming rules of the plan file, and name the plan file as: radiotherapy number_treatment number_split plan number_split plan number. Take the plan name S160281_Ci_j_Tk as an example, where S160281 is the patient’s radiotherapy number, Ci represents the i-th course of treatment (C is the abbreviation of course), j represents the j-th plan after plan splitting, Tk represents multi-target irradiation, sometimes Different target areas need to be irradiated in different plans, and k represents the number of split plans. For example, if a patient with radiotherapy number S160281 is undergoing CyberKnife treatment for the first time, if the patient has a target volume in the head and abdomen, respectively, Tumor1 and Tumor2, if Tumor1 and Tumor2 are treated ...

Embodiment 3

[0159] This embodiment is a computer-readable storage medium corresponding to the above-mentioned embodiments, on which a computer program is stored, and when the program is executed by a processor, the following steps are implemented:

[0160] Acquiring the treatment plan file from the Cyberknife radiotherapy planning system, the treatment plan file including the irradiation field path file, the plan file and the plan report file;

[0161] Obtain basic plan parameters according to the irradiation field path file, plan file and plan report file;

[0162] Obtain the dose-volume histogram for each organ from the planning report file;

[0163] According to the dose volume histogram, the irradiation dose information and volume information of the organ at risk are obtained.

[0164] Further, the acquisition of irradiation dose information and volume information of organs at risk according to the dose volume histogram is specifically:

[0165] Obtain the dose corresp...

Description

technical field [0001] The present invention relates, in particular, to a method for automatically extracting parameters of a cyberknife treatment plan and a computer-readable storage medium. Background technique [0002] In recent years, with the rapid development of accelerator technology and image-guided technology, radiotherapy has gradually entered the era of precision medicine, and stereotactic body radiation therapy (SBRT) is a typical representative of precision radiotherapy technology. Cyberknife has the characteristics of multiple degrees of freedom, full coverage of three-dimensional angles, multiple tracking methods, and fast dose gradient drop. It can better protect the normal tissues around the target area while ensuring high doses in the target area. . However, this also brings certain challenges to physicists in extracting planning parameters and assessing normal tissue exposure. This is because the mechanical structure and software design of the CyberKnife ...
