Embodiment Construction

[0047] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] The main solution of the embodiment of the present invention is: provide a kind of calculation method of pure software, obtain the technical problem of DAP dose-area product accurately without expensive measuring instrument

[0049] Because the prior art uses a high-precision device to obtain the dose-area product, but the cost of the device is high, it will increase the purchase cost of the hospital and the medical treatment cost of the patient, and there will be deviations, so it is not suitable for single-exposure digital X-ray photography system.

[0050] The present invention provides a solution. By correcting instructions, the mapping relationship between the dose value of X-rays on the surface of the detector and the voltage and milliampere-seconds is obtained, and the information parameters of X-rays on...

Abstract

The invention discloses a dosage area measuring method of digital X ray. The method includes following steps: detecting information parameters of X ray projected by an X ray source to the surface of adetector, wherein the information parameters include projection size of the X ray on the surface of the detector, exposure parameters and distance D from the X ray source to the detector; according to the information parameters, acquiring area and dosage value of the X ray projected at an opening of a beam limiting device, wherein the beam limiting device is positioned between the X ray source and the detector; according to the area and the dosage value of the X ray projected at the opening of the beam limiting device, generating dosage area value at the opening of the beam limiting device. The invention further discloses a dosage area measuring system of the digital X ray and a storage medium. A pure software calculation method is provided, and DAP dosage area product can be acquired accurately without using expensive measuring instruments.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a digital X-ray dose area measurement method, system and storage medium. Background technique [0002] With the continuous development of medical technology and medical diagnosis methods, X-ray photography technology has been widely used in the fields of clinical diagnosis and medical research. For example, chest X-ray examination is of great significance to the early detection of lung cancer; fracture is the most common disease in the emergency department, and X-ray photography can quickly and accurately locate and diagnose the fracture location. In short, X-ray photography technology has brought great help to patients' disease examination and doctor's diagnosis, and has become an indispensable means of examination. [0003] However, while patients benefit from X-ray examinations, they also bear the radiation damage caused by X-rays to the body. According to the principle of ...
