Problems solved by technology

[0004] The purpose of the present invention is to provide a precise radiotherapy head positioning frame to solve the above-mentioned background technology. First, it is necessary to reset the marked coordinates on the patient's fixed membrane or skin twice, which leads to the repeatability of the positioning function and the accuracy of the treatment. The inaccuracy error is larger; second, the problem of large positioning error in space positioning coordinates

Abstract

The invention provides a precision radiotherapy head positioning frame. The precision radiotherapy head positioning frame comprises a positioning frame, an upper side fixing frame and an installing plate base; two side plates of the positioning frame are provided with Z-shaped positioning structures; the inner side edges of the two groups of Z-shaped positioning structures are provided with metalwires; the rear side of the positioning frame is provided with an arc postposition plate; the top end of the positioning frame is fixedly provided with the upper side fixing frame; the front side edgeof the upper side fixing frame is provided with an X-axis scale label; the upper edge of the right side plate of the positioning frame is provided with a Y-axis scale label; and the front side edge of the right side plate of the positioning frame is provided with a Z-axis scale label. The precision radiotherapy head positioning frame provided by the invention realizes the effects of positioning aradiotherapy head, and through built-in Z-coordinate setting of the Z-shaped positioning structures, the beneficial effects of convenient positioning and more accurate positioning are realized, and acoordinate can be calculated conveniently after a treatment plan is made.

Description

technical field [0001] The invention relates to the technical field of head positioning frames for medical equipment, in particular to a head positioning frame for precise radiotherapy. Background technique [0002] With the development of modern tumor radiation therapy technology, the pursuit of precise and precise radiotherapy can minimize the normal tissue damage and side effects of patients. First of all, it is necessary to reduce errors in all aspects, such as positioning errors, positioning errors, image transmission and treatment plan planning errors, and machine equipment index errors, etc. The errors that cause the largest errors are positioning and positioning errors. [0003] At present, radiotherapy positioning for head tumors is cumbersome. Creatively reducing the positioning steps also reduces errors. For existing head radiotherapy positioning and positioning, first make virtual X, Y, and Z marking points on the surface of the head mask, then perform position...
