Accelerator therapy device

Abstract

The invention discloses an accelerator therapy device which comprises a therapy control device, a main frame and an accelerator. The accelerator is arranged on the main frame. The therapy control device controls the accelerator and the main frame. The accelerator therapy device further comprises a main frame adapter, a bracket, a pitch drive device and a balancing assembly. According to the invention, the main frame adapter is creatively arranged; the main frame and the balancing assembly are respectively arranged on both sides of a rotation shaft of the main frame adapter; the balancing assembly, equipment arranged thereon, the main frame and equipment arranged thereon respectively apply opposite torque on the rotation shaft of the main frame adapter; two torques are mutually offset or partially offset; when the whole main frame adapter and the main frame carry out pitch rotation, needed external torque is small; and the manufacture cost of an external drive and the complexity of a control system are greatly reduced.

Description

technical field [0001] The invention relates to an accelerator therapy device, in particular to an accelerator therapy device. Background technique [0002] With the development of tumor radiology and material science, as an important means of cancer treatment, radiotherapy has gradually entered the era of "three precisions" of precise positioning, precise planning and precise treatment. When the rotation plane of the main frame is set to be perpendicular to the horizontal plane, the rotation plane is the X plane. At this time, its rotation axis is defined as the Z axis, and the horizontal line perpendicular to and intersecting the Z axis is the X axis, which is perpendicular to the Z axis and the X axis respectively. The straight line that both intersect is the Y axis. The Z axis and the Y axis establish the Y plane, the Y axis and the X axis establish the X plane, and the Z axis and the X axis establish a horizontal plane (Z plane). The current medical linear accelerator...

Problems solved by technology

Generally speaking, during treatment, the patient's lesion is placed at the isocenter, and the main frame is rotated so that the accelerator rotates around the lesion on the X plane or its parallel plane, so that the ray irradiates the lesion from different directions to better Kill diseased cells, however, both the patient and the lesion have a three-dimensional volume, and the current treatment equipment can only perform 360° irradiation from a plane space, but cannot achieve three-dimensional spherical space irradiation
