Embodiment

[0062] During the chest examination of the digital X-ray machine, the operating technician operates the digital X-ray machine to select the chest examination. When the examinee enters the sensing range, the 0-point exposure system starts to calculate the examinee’s body position, body thickness, weight, shoulder thickness, and height , shoulder height, leg length, knee height and other parameters, combined with the proportion model of human body structure and big data model, under the premise of ensuring that the inspection report that meets the clinical requirements can be produced, and under the principle of minimizing the impact of X-rays on the examinee, The appropriate kV and smaller mAs parameters are determined and calculated, and the window opening size of the beamer is automatically controlled. After determining the subject’s position for filming, the operator does not need to set the exposure parameters, and can complete the inspection by executing the exposure command...

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...
