Problems solved by technology

However, protons and carbon ions in the treatment of eyeball tumors generally use a single-field injection method, and the selection of the injection path may have a greater impact on the dose to normal tissues. The location of the tumor (the gaze angle of the eyeball) determines the incident path to a certain extent. , so those skilled in the art need to design a technical positioning that can solve or alleviate the above-mentioned problems or some of the problems

Abstract

The invention discloses a positioning platform for proton heavy ion radiotherapy of an eyeball tumor patient. The positioning platform comprises a head fixing part used for fixing a head and keeping the position unchanged; the eyeball positioning assembly adopts an LED point light source array, and each LED lamp bead in the LED point light source array is controlled by an independent switch; the eyeball tracking assembly adopts an eyeball motion capturing unit, the eyeball motion capturing unit is arranged on a three-axis moving frame, the three-dimensional position of the eyeball motion capturing unit is adjusted, and the eyeball motion capturing unit is used for collecting a position image of an iris; the eyeball positioning assembly is arranged over the head fixing part, the eyeball tracking assembly is arranged on the side edge of the head fixing part, head positioning and eyeball positioning tracking are used in a matched mode, the head of the human body can be completely limited and fixed, the staring position of eyeballs can be completely fixed, and zero displacement can be achieved or close to.

Description

technical field [0001] The invention relates to the field of radioactive medical devices, in particular to a positioning platform system for proton heavy ion radiotherapy for ocular tumor patients. Background technique [0002] Proton and heavy ion therapy are currently advanced treatment technologies in the field of radiation therapy. Because ions have the physical characteristics of the Bragg peak, most of the energy can be deposited in the Bragg peak area, and the incident area and beam lateral and terminal doses are low, so that it can Reduce the exposure dose to normal tissues around the target area. Carbon ions also have high biological effects, and have a good curative effect on tumors that are not sensitive to radiation. [0003] Uveal malignant melanoma is a rare ocular malignancy, including choroidal melanoma, ciliary body melanoma, and iris melanoma. The incidence rate in Europe is 5-7 cases / year per million people, and the incidence rate in Asia is 0.4-0.6 case...
