Method for determining radiotherapy dose according to characteristic parameters of tumor molecular images

Abstract

A method for determining the dose of radiotherapy according to the characteristic parameters of tumor molecular images, firstly using the previous patient data to train the neural network model, and confirming the accuracy of the neural network through cross-validation, and secondly using the patient data and the scoring rules of the present invention to construct a dose determination empirical equation. For newly admitted patients, the radiotherapy dose can be predicted according to these two models, and finally the screening rules are used to determine whether the prediction results are available. If not, the final radiotherapy dose is determined by the doctor.

Description

technical field [0001] The invention relates to the field of medical radiation, in particular to a method for determining radiotherapy doses according to characteristic parameters of tumor molecular images. Background technique [0002] The incidence of pre-cancer remains high, and the treatment of cancer has attracted more and more attention. In the process of cancer treatment, surgery, radiotherapy and chemotherapy are the three most commonly used and effective methods. Radiotherapy can be used alone as a means of cancer treatment , can also be combined with other methods for adjuvant therapy, so it is used in most cancer treatments. The basic principle of radiotherapy is to ensure that the target tumor area can receive sufficient radiation dose, and at the same time reduce or avoid radiation damage to the invaded tissue as much as possible. The biggest difficulty in radiotherapy is how to ensure that the tumor target area receives an accurate radiation dose. In recent y...

Problems solved by technology

At present, when making radiotherapy plans for patients, the choice of radiotherapy dose is still based on the empirical value given by the doctor. Due to the difference in the patient's constitution and disease progression, it is likely that the radiotherapy dose given by the doctor is not suitable for the patient, resulting in radiation. The treatment plan cannot be particularly suitable for the patient. Insufficient radiotherapy dose will cause uncontrolled tumors. Excessive radiotherapy dose will cause damage to normal tissues.
