accelerator therapy device

Abstract

The invention discloses an accelerator treatment device. The accelerator treatment device comprises a treatment control device, a main frame and an accelerator, the accelerator is installed on the main frame, the treatment control device controls the accelerator and the main frame, and the accelerator The treatment device also includes: a main frame adapter, a bracket, a pitching drive device, and a balance assembly. The invention creatively sets a main frame adapter, and sets the main frame and the balance assembly on both sides of the main frame adapter's rotating shaft, respectively. The balance assembly and the main frame and the equipment installed on it respectively apply opposite torques to the main frame adapter rotating shaft, and the two torques cancel each other or partially cancel each other, so that when the entire main frame adapter and the main frame are pitched, the required external torque is very small, so that This greatly reduces the manufacturing cost of the external drive device and the complexity of the control system.

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
