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 present invention relates to the technical field of calibration devices for medical equipment, in particular to a field verification device for medical equipment, comprising: a central calibration piece and at least two boundary calibration pieces; a central detection block is arranged on the central calibration piece, and the central detection block It is used to mark the center of the light field; at least two boundary marking pieces can move relative to each other, and each boundary marking piece is provided with a boundary detection block, which is used to mark the boundary of the light field; the center detection block and the boundary detection The blocks are made of radiation shielding material. In the radiation field verification device of the medical equipment, the center and boundary of the light field can be clearly displayed in the image of the radiation field, so that the deviation between the light field and the radiation field can be directly verified. In this way, there is no need to use a film to verify the deviation of the light field and the radiation field, but the test result can be given relatively quickly, the response is good, and the test result is more intuitive and accurate, while reducing the cost of the radiation field verification.

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...
