0-point automatic exposure control method and system for medical X-ray equipment

Abstract

The invention provides a medical X-ray equipment zero-point automatic exposure control method and system, and the method comprises the steps: judging the parameters of a detected person through a sensing detection part after the detected person enters a sensing range, calculating the parameters of kV, mAs and the like of medical X-ray equipment according to the detection body position set by the medical X-ray equipment in combination with a human body structure scale model and a big data model, and carrying out the zero-point automatic exposure control of the medical X-ray equipment. And an instruction is given to enable exposure parameters of the medical X-ray equipment to be set in a full-automatic mode, and inspection is completed. The invention has the following beneficial effects: on the premise of ensuring clinical examination quality, it is ensured that an examinee absorbs a small dose, the influence of X-rays on the examinee is reduced as much as possible, and zero-point automatic exposure is realized; x-ray shooting is more convenient and efficient, and the inspection time period is shortened; and meanwhile, the experience requirement on parameter configuration of an operation technician is reduced to a great extent.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a zero-point automatic exposure control method and system for medical X-ray equipment. Background technique [0002] In the medical field, X-rays are widely used in medical diagnosis, especially for non-invasive diagnosis of conditions inside a patient. [0003] X-rays can penetrate the human body to the imaging device and finally generate a diagnostic image. Different tissues in the human body have different absorption intensities on X-rays, so there will be differences in the number of X-rays that penetrate the human body and reach the imaging device. This difference can lead to diagnostic images. The difference in gray levels in the image can help doctors make a diagnosis. Excessive X-rays for a long time will cause harm to the human body, so the exposure dose of X-rays received by the human body must be strictly controlled during the medical diagnosis pro...
