Problems solved by technology

For this integrated CT-guided linear accelerator, the CT scan hole occupies a large area near the LINAC isocenter. In order to avoid the mutual interference between the parking position of the EPID support arm and the CT SIM function, the recovery parking position of the EPID support arm is restricted.

Abstract

The invention provides a detector supporting device, a route planning system and a radiotherapy apparatus. The detector supporting device is suitable for supporting a detector in the radiotherapy apparatus; the detector can be folded or unfolded according to different use conditions. In a folded state, the detector supporting device has no interference with functions of CT SIM and the like of theradiotherapy apparatus. The route planning system is suitable for calculating and optimizing the displacement amount and the movement trajectory of each moving component in the detector supporting device to avoid any collision between the detector supporting device and an accommodation hole accommodating the detector supporting device; and the setting time of the detector is minimized.

Description

technical field [0001] The invention mainly relates to image-guided radiotherapy equipment, and in particular to a detector supporting device and a path planning system. Background technique [0002] In order to achieve precise radiation therapy and improve the efficiency of tumor treatment, image-guided radiation therapy (IGRT) is widely used in clinical practice, among which Electronic Portal Imaging Device (EPID) is the most advanced technology for IGRT. Commonly used image-guided equipment can precisely locate the tumor location before or during treatment, help doctors judge whether the patient is positioned correctly, and judge whether the location or shape of the tumor has changed, etc., so as to reduce the possibility of normal tissues being irradiated and reduce the Side effects, improve treatment efficiency. [0003] At present, for the medical linear accelerator (Linear Accelerator, LINAC) produced in my country and Elekta (Elekta), EPID can only be imaged at a fi...
