Abstract

The invention discloses radiotherapy equipment possessing a radiation field boundary identification function. In the invention, a lens component is used to replace a reflection apparatus and an external light source can select a light source with a small diameter light beam, such as a laser light source, an LED spot light source and the like. The lens component possesses a beam expanding effect and the size of the lens component can be smaller than that of the reflection apparatus in the prior art so that a space occupied by the reflection apparatus can be effectively saved.

Description

technical field [0001] The invention relates to an accelerator therapy device, in particular to a radiation therapy device for radiation therapy with the function of marking the field boundary. 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. Among them, it is necessary to confirm the shape and position of the radiation field before treatment, so that the patient can be positioned and the radiation field adjustment device (such as a collimator, etc.) can be adjusted. The light passes through field control devices such as collimators or light-limiting tubes, and projects the outline of the field on the patient or phantom, and also determines the position of the field. For example, CN103212164A discloses a method for calibrating the radiation field / simulated light ...
