Embodiment Construction

[0019] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] combine figure 1 As shown, the intensity-modulated radiation therapy device in the present invention can generate X-rays or γ-rays, and adopts a CT-ring frame structure and can use a single beam 1 or three beams of radiation sources 1, 2, 3 at the plane intersection angle For stereo focusing, the frame includes an inner ring frame 7 and an outer ring frame 8 . Wherein, the radiation source generating equipment and the radiation beam monitoring device (not shown) are installed on the inner ring frame. The inner ring gantry is capable of rotating ±180° about the outer ring gantry, and the inner and outer ring gantry are tilted together ±30° about their longitudinal axis to form a spatial focus and can provide 1 to 108 An irregular non-coplanar intensity-modulated field of arbitrary shape ranging from 0×0 to 30×30 cm (centimeter). At lea...

Abstract

The invention discloses an intensity-modulated radiation therapy apparatus. The apparatus can provide rapid and effective therapy, and also can realize real-time monitoring of the ray beam of the therapy apparatus and the running state of a multi-leaf collimator during radiation and real-time detection of the shape and the dosage of a radiation field. The apparatus comprises a radiation source generating device and a ray beam monitoring device which are mounted on an inner annular frame; and the inner annular frame can rotate around an outer annular frame by + / - 180 DEG, the inner annular frame and The outer annular frame can tilt by + / - 30 DEG around their longitudinal axes, and at least one independent ray beam monitor is mounted on a bracket at the therapy ray beam outlet end of the inner annular frame to monitor the therapy ray beam and the running state of the multi-leaf collimator operating status during radiation. The therapy apparatus reserves the characteristics of X-knife orgamma-knife multi-field spatial focusing, also reserves the advantages of the large field intensity-modulated radiation therapy of conventional cobalt-60 therapy machines and medical accelerator therapy machines, and can enforce X-knife or gamma-knife radiation on large-size tumors.

Description

technical field [0001] The present invention relates to a therapeutic device, more specifically, the present invention relates to a radiation intensity modulation therapeutic device. Background technique [0002] Cancer has become the main killer that endangers human health, and it is one of the main diseases that threaten the health of our country. Radiation therapy is still one of the main means of treating malignant tumors, and about 65% to 70% of tumor patients need to receive radiation therapy to varying degrees. [0003] Before the 1980s, two-dimensional radiotherapy was the main technique for tumor radiotherapy. After entering the 1990s, China's tumor radiotherapy technology has entered the era of 3D radiotherapy from the era of 2D radiotherapy, and three-dimensional conformal (3D-CRT) and intensity-modulated radiotherapy (IMRT) treatment technologies have appeared, and stereotactic therapy Such as X-knife (X-knife), gamma knife (γ-knife) treatment technology, etc.,...
