However, such an approach requires a lot of manpower and material resources, so it is rarely adopted by hospitals
[0005] At present, the traditional automatic treatment method cannot be widely used in the actual clinical treatment, and there are mainly the following problems and shortcomings:
[0006] 1. The traditional automatic treatment method is based on the general commercial planning system. When generating a new treatment plan, it is necessary to calculate and solve large-scale dose calculation and optimization problems. The calculation time is very long and cannot be completed within a clinically acceptable time
[0007] 2. This method requires the dosimetrist to participate in the optimization process of the plan. It takes a long time to set and adjust the parameters manually, and the quality of the treatment plan is also directly limited by the experience and judgment of the dosimeter.
[0008] 3. In the end, the new treatment plan needs to perform quality assurance (Quality Assurance, QA) on the phantom again, and the optimization of automatic radiotherapy plan and the integration of automatic quality assurance cannot be realized
[0009] Looking at the current radiation therapy models at home and abroad, traditional radiation therapy does not take into account the changes in the patient's anatomical structure during the treatment process, so the expected treatment goals cannot be achieved. If offline automatic radiation therapy is performed based on a commercial treatment planning system, the efficiency Low, time-consuming and labor-intensive, so it is difficult to widely use clinically

Embodiment 1
[0119] When an untreated tumor patient (Subject) comes to the radiation therapy department, a set of tumor localization CT images will be called out or taken for the patient first, and the doctor will read the relevant medical history and relevant examination reports. The next steps are as follows:
[0120] Step (1): Read patient data, which includes tumor images and image information of surrounding organs and tissues, including CT (Computed Tomography), cone-beam CT (Cone-Beam CT), ultrasound (Ultrasound, US), PET (PositronEmission Tomography) or Magnetic Resonance (Magnetic Resonance, MR) and other images; and information including the patient's basic data and relevant medical history;
[0121] Step (2): Based on the information in step (1), judge the patient who has not been treated, then start to extract the image structure features for the image data of the new patient, establish the image ID, and search the database based on the image ID information. The most similar se...
Embodiment 2
[0165] When a treated tumor patient (Subject) goes to the radiotherapy department for subsequent fractionated treatment, after confirming the relevant information of the patient, the follow-up steps are as follows:
[0166] Step (1): Read the image data of the patient, which contains the image information of the patient's tumor and its surrounding organs and tissues before the fractional treatment, including CT (Computed Tomography), Cone-Beam CT (Cone-Beam CT), Ultrasound (Ultrasound , US), PET (Positron Emission Tomography) or Magnetic Resonance (Magnetic Resonance, MR) and other images; and information including the patient's basic information related to medical history;
[0167] Step (2): Based on the information in step (1), it is judged as the patient who has been treated, and the image data file (Template) that is the closest to this treatment is searched;
[0168] Step (3): based on the discriminant result of step (2), extract the nearest image group and outline image ...

Abstract
The invention discloses a method for implementing an automatic and composite radiation therapy plan. The method includes the following steps: acquiring specific image features of a patient and saving the image features to a database; at thebeginning of preparing a patient radiation therapy plan, with the image features as searching criteria, searching for a most identical image group from the database of image features and extracting the image group and taking the image group as a sample group, selecting an appropriate a registration algorithm on the demands of clinic application and performing corresponding operation, introducing a target area sketch information to a patent image, and automatically sketching the target area and an endangered organ; after a doctor confirming the result of the sketching, inputting relevant therapy dose parameters, automatically conducting dose distribution simulation operation on the radiation therapy plan, a physician or physicist confirming the result of the simulation, thus completing the radiation therapy plan. According to the invention, the method can improve the sketching of the target area and information of relevant organs in a precise manner, and can be applied to the field of tumor radiation therapy; the method can quickly generate a new treatment plan for the patient and provide evidence for the physician to make profession determination as long as an anatomical structure image of the patient is acquired.
Description
technical field [0001] The invention relates to a method for compound automatic radiotherapy planning, in particular to an automatic online compound optimization application method of radiotherapy plan. Background technique [0002] In the process of radiation therapy (Radiation Therapy), the patient's positioning CT is first scanned, and then the target area is delineated by the doctor and the outline of the organs at risk, and then designed by the physicist or dosimetrist through the commercial Treatment Planning System (TPS) The treatment plan is optimized, and the quality assurance of the treatment plan is carried out by a physicist. Finally, the treatment plan can be used in the subsequent fractionated (Fraction) treatment sessions. [0003] However, such a treatment modality does not take into account the patient's anatomical changes during subsequent treatment sessions, such as changes in tumor volume and location, changes in patient body contours, changes in gastroin...
