Homologous dual-energy accelerator and accelerator therapy device

Abstract

The invention discloses a homologous dual-energy accelerator and a therapy device comprising the homologous dual-energy accelerator. The homologous dual-energy accelerator comprises an electron emitting device and an accelerating device, wherein the electron emitting device is positioned at the input end of the accelerating device, and generated electrons are emitted from the output end of the accelerating device after being accelerated by the accelerating device. The homologous dual-energy accelerator also comprises at least one separation deflection device, wherein the separation deflection device is arranged on one side of the output end of the accelerating device and is used for changing the motion trails of partial electrons in the electrons after being accelerated by the accelerating device. The homologous dual-energy accelerator has the advantages that the inventor discovers that the speeds and energy of all electrons are not completely the same after the electrons are accelerated by the accelerating device; the inventor uses the separation deflection device arranged on one side of the output end of the accelerating device by using the discovery, the motion trails of partial electrons with relatively low energy level in particles after being accelerated by the accelerating device are forced to be changed, and the electrons with different energy levels in a homologous electron beam are separated, so that the electron beam with two energy levels is obtained, one path of the electron beam with high energy level continues an original path and is used for radiation therapy, and the other path of the electron beam with low energy level is used for tracking focus of infection and detecting the therapeutic effect.

Description

Technical field [0001] The invention relates to an accelerator treatment device, in particular to a homologous dual-energy accelerator and an accelerator treatment device. Background technique [0002] With the development of tumor radiology and material science, as an important means of treating cancer, radiotherapy has gradually entered the "three essences" era 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, the rotation axis is defined as the Z axis, and the horizontal line perpendicular to and intersecting with the Z axis is the X axis. The straight line that intersects is the Y axis. The Z and Y axes establish the Y plane, the Y and X axes establish the X plane, and the Z and X axes establish the horizontal plane (Z plane). The current medical linear accelerator (radiotherapy equipment) drives the accelerator to rot...

Problems solved by technology

However, the solution is actually a complex accelerator tube control system, poor stability, and difficult to apply commercially.

The other is a dual-source system, that is, a KV-level accelerator is integrated on the existing MV-level accelerator system, so that the system has two different levels of radiation at the same time. This system also has problems such as high cost and cumbersome structure.
