Abstract

The present application relates to pulse parameter adjustment systems and methods. The method includes: acquiring information related to the treatment plan; determining a look-back window based on the information related to the treatment plan; based on the information related to the treatment plan and the look-back window, determining Determining a prospective window based on the information related to the treatment plan; determining prospective information related to the prospective window based on the information related to the treatment plan, the retrospective information and the prospective window; and determining one or more pulse parameters of the look-ahead window based on the look-ahead information. This application uses a closed-loop control system to predict the parameters of the pulses to be sent according to the parameters of the pulses that have been sent, so as to reduce or even eliminate errors and fluctuations in the output radiation dose.

Description

[0001] cross reference [0002] This application claims priority from the following applications: [0003] U.S. Application No. 15 / 690,363, filed August 30, 2017. [0004] The content of the above application is incorporated herein by reference. technical field [0005] The present application relates to a radiation dose adjustment system and method, in particular to a pulse parameter adjustment system and method during radiotherapy. Background technique [0006] Radiation therapy (RT, RTx, or XRT for short) is a method that can control or kill malignant cells and is used for cancer treatment. This therapy can usually be achieved with linear accelerators, particle accelerators or radioactive sources (teletherapy). Radiation therapy can also be applied to many other medical conditions, including control of the immune system and treatment of inflammation. Historically, radiation therapy devices, such as linear accelerators, typically had several fixed radiation output rate...
