Abstract

The embodiment of the invention discloses a pressure motion protection method of a breast X-ray machine. The method includes the steps that current pressure output by a drive mechanism of a drive pressure application device of the breast X-ray machine is collected; a current maximum pressure protection value corresponding to the current pressure is determined according to a mapping relation between the pressure and the maximum pressure protection value, wherein the current maximum pressure protection value is smaller than or equal to a final maximum pressure protection value; drive control parameters are calculated according to the current maximum pressure protection value; the drive mechanism is controlled to output pressure which is not larger than the current maximum pressure protection value according to the drive control parameters. The embodiment of the invention further discloses a pressure motion protection device of the breast X-ray machine and a breast X-ray machine system. By the adoption of the technical scheme, damage to detected patients can be reduced or avoided.

Description

technical field [0001] The present application relates to the field of information control technology, and in particular to a compression movement protection method and device for a mammary X-ray machine and a mammary X-ray machine system. Background technique [0002] The mammography machine irradiates the subject's breast with X-rays to form an image, and then diagnoses the subject's disease condition based on the image. When imaging a subject, in order to improve the image quality and reduce the radiation dose to the subject, it is usually necessary to use a compression plate to press the breast of the subject against the supporting surface on the detector. Because the driving device that pushes the compression plate to squeeze the breast is automatically controlled by electricity, and the electric control has the risk of getting out of control, once it gets out of control, it is very easy to cause injury to the body of the examinee. In order to avoid causing harm to the...
