Abstract

The embodiment of the invention discloses image-guided radiotherapy equipment. The image-guided radiotherapy equipment comprises an annular rack, a radiotherapy head, a strip-shaped imaging source anda strip-shaped imager, wherein the annular rack can rotate around a central shaft; the radiotherapy head is arranged on the annular rack and is used for emitting treatment beams; the strip-shaped imaging source comprises a plurality of imaging sub-sources and is capable of respectively emitting imaging beams; the plurality of imaging sub-sources are arranged at positions close to the radiotherapyhead in a first direction; the strip-shaped imager is arranged on an opposite side of the strip-shaped imaging source in a second direction intersecting with the first direction and is used for receiving imaging beams passing through an affected part of a patient and converting the imaging beams into a three-dimensional imaging signal so as to generate a three-dimensional image of the affected part of the patient.

Description

technical field [0001] The invention relates to the technical field of radiation therapy, in particular to an image-guided radiation therapy device. Background technique [0002] Image Guided Radiation Therapy (IGRT) technology uses imaging devices to locate the patient's target area before treatment, and to perform real-time positioning and tracking during treatment, so as to achieve precise radiotherapy for tumors and reduce the risk of damage to normal tissues and key organs around the tumor. organ damage. [0003] figure 1 As a traditional image-guided radiation therapy equipment, such as figure 1 As shown, the radiotherapy equipment includes an annular frame rotatable around a central axis, a radiotherapy head (such as a multi-source focus therapy head) and an imaging device arranged on the annular frame. Among them, the radiotherapy head is used to emit treatment beams to perform radiotherapy on the patient's tumor target area A (the target area A is located on the ...
