Mammary radiography machine and automatic exposure control method of mammary radiography machine

Abstract

The embodiment of the invention provides a mammary radiography machine and an automatic exposure control method of the mammary radiography machine. The mammary radiography machine comprises a high-pressure generator, a DIOS automatic exposure control device, a DIOS control device, a pressure control device, a terminal and other parts. The pressure control device compresses a target object to an optimum compression strength and transmits the thickness of the target object to the terminal, and the terminal calculates optimum exposure parameters according to the thickness of the target object, transmits the exposure time duration in the exposure parameters to the DIOS automatic exposure control device through the DIOS control device, and transmits the current value and the voltage value in the exposure parameters to the high-pressure generator; the high-pressure generator generates X rays for exposure according to the obtained exposure parameters, and after the exposure time meets the requirement of the exposure time duration obtained by the DIOS automatic exposure control device, the DIOS automatic exposure control device controls the high-pressure generator to end exposure. According to the mammary radiography machine and the automatic exposure control method of the mammary radiography machine, automatic exposure control is achieved, and the problem that the exposure parameters are artificially set, so that overexposure or underexposure is caused is avoided.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a mammography machine and a method for controlling automatic exposure of the mammography machine. Background technique [0002] Breast cancer is one of the most common cancers, and its incidence rate ranks first in the incidence rate of female malignant tumors. Early detection of breast cancer by mammography is the most convenient and reliable non-invasive detection method for diagnosing breast diseases. [0003] At present, the latest mammography machine on the market is a digital mammography machine. The digital mammography machine adopts digital imaging, which can post-process the image; the production time is short, and the image can be obtained immediately and the quality of the film can be checked; the radiation dose required for filming is reasonable. But its price is very expensive, and most hospitals in our country still use simulated mammary gland machines. ...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the problems of the prior art are: the digital mammography machine is expensive, and the cost is high, and the digital upgrade of the analog mammography machine still needs to manually set the exposure parameters, which is easy to cause overexposure or underexposure, so that the patient is exposed to excessive radiation or the resulting image is not clear
