Multimodal guided adaptive radiotherapy system

Abstract

The invention discloses a multi-mode guided self-adaptive radiotherapy system, which mainly includes a double kilovolt level X-ray imaging system, an infrared positioning and tracking system, and a megavolt level X-ray imaging system. The present invention integrates images of different modes and dose signals, and integrates an external dual X-ray imaging system, an infrared positioning tracking system and a megavolt-level X-ray imaging system installed on an accelerator, so that it can be simultaneously performed during the treatment process. Real-time tracking and correction of the tumor position and verification of the radiation dose, realizing dynamic adjustment, real-time solution to problems such as the position and shape of the target area in radiotherapy, updating the treatment plan according to the latest anatomical structure of the patient before each treatment, and timely adjusting the placement during radiotherapy Positioning and correcting the errors caused by the movement of the target area guides this and subsequent treatments to ensure that the tumor target area receives an accurate prescription dose, thereby realizing adaptive radiotherapy.

Description

technical field [0001] The invention relates to the technical field of tumor radiotherapy, in particular to a multi-mode guided self-adaptive radiotherapy system. Background technique [0002] In precise tumor radiotherapy, it is necessary to collect patient image information at an appropriate period during each fractional treatment as feedback and compare it with diagnostic images and planned images to correct setup errors and field position errors. At present, most of the clinical use is to combine the linear accelerator with a separate imaging device such as X-ray, ultrasound, infrared, etc., to obtain the image data of the patient before and during the treatment, and to analyze the target area and the target area before each treatment or treatment. The structure and position of the surrounding organs at risk are compared, and it is impossible to adjust the position of the tumor target area and the radiation dose in real time at the same time. [0003] Therefore, it is u...
