Abstract

The invention discloses a simulated medical electron linear accelerator for teaching, relates to the technical field of teaching equipment, and aims to solve the complex technical problem. The accelerator specifically comprises a frame structure, a shaftless rotating mechanism, an accelerating mechanism and an image collecting mechanism, wherein the frame structure comprises a base, a vertical plate and a first shell cover; the vertical plate and the first shell cover are fixedly installed on the outer wall of the top of the base; the inner wall of the vertical plate is rotationally connectedwith a rotating ring; and the shaftless rotating mechanism is arranged on the outer wall of the side, close to the first shell cover, of the rotating ring. The tungsten wire heating principle is usedfor generating electrons, the electrons are accelerated by an accelerating coil and hit on a tungsten sheet to generate photons, and the photons form a conical light beam through a collimator; due tothe fact that the energy of the conical light beam decreases progressively from the center line position of the conical light beam to the periphery, the energy can be homogenized and then emitted outthrough the collimator for radiotherapy; and the whole process is relatively concise under the condition of ensuring the reliability, and the use cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of teaching equipment, in particular to a simulated medical electronic linear accelerator for teaching. Background technique [0002] Medical electron linear accelerator is a large-scale medical equipment that uses microwave electric field to accelerate electrons to generate high-energy rays, which is used for long-distance external irradiation radiation therapy activities in human medical practice. However, the existing medical electron linear accelerator has complicated accelerator technology and maintenance The requirements are high, the price is high, and the treatment cost is also high. [0003] After searching, the Chinese patent publication number is CN205029955U, which discloses a medical electronic linear accelerator, including an acceleration tube, a vacuum system, a control system, an electron gun, a deflection magnet, a directional rake, a treatment head, a pulse modulator, a magnetron, The circ...
