Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the following embodiments will be used to further describe the field verification device and verification method of the medical equipment in conjunction with the accompanying drawings in detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and s...

Abstract

The invention relates to the technical field of calibration devices for medical treatment equipment, in particular to a medical treatment equipment radiation field testing apparatus which comprises acenter calibrating part and at least two boundary calibrating parts. The center calibrating part is provided with a center detection block which is used for marking the center of a light field. The boundary calibrating parts are movable relatively; each boundary calibrating part is provided with a boundary detection block for marking the boundary of the light field. The center detection block andthe boundary detection blocks are made of ray shielding materials. According to the medical treatment equipment radiation field testing apparatus, the center and the boundary of the light field can bedisplayed clearly in a field image, and thus deviation of the radiation field and the light field can be tested directly. The way of testing the deviation of the light field and the radiation field by the aid of photographic films is omitted and test results can be obtained within a short time. Besides, the apparatus has good responsibility, its test results are more visual and accurate, and thecost for testing of the radiation field is lowered.

Description

technical field [0001] The invention relates to the technical field of calibration devices for medical equipment, in particular to a field verification device and verification method for medical equipment. Background technique [0002] Radiodiagnosis and treatment equipment is currently widely used medical equipment. For example, conventional radiation therapy needs to generate an X-ray irradiation field at a certain distance from the X-ray source, so as to perform radiation therapy on tumors of a certain size and shape in the patient's body. The irradiation field, also known as the radiation field, refers to the projection of the ray beam on the isocentral plane, and it is precisely the area defined by 50% of the dose intensity in the central area of ​​the beam. The outline of the irradiation field represents the range of radiation. If the range of radiation is not consistent with the expected range of irradiation, some parts of the target area will be missed, and in serio...
