Hemioptic Geometry Mammography Apparatus

Abstract

The invention relates to a semi-vision geometry mammography X-ray imaging device, which comprises a frame, lead glass is arranged on the side of the frame, a C-shaped arm is arranged on one side of the lead glass, and the C-shaped arm includes an X-ray tube device arranged obliquely at the upper end and the image receiver at the lower end, a molybdenum / rhodium filter conversion device is provided on the lower side of the X-ray tube device, an image detector is provided at the bottom of the image receiver, and a molybdenum / rhodium filter conversion device and the image receiver are provided The X-ray tube device can be moved up and down and rotated left and right. The X-ray tube device is designed according to the principle of half-view geometry. The angle of inclination depends on the anode angle of the X-ray tube and the source image distance. The molybdenum / rhodium filter conversion device is controlled by the conversion motor. The present invention is simple in structure, easy to operate, and the half-view geometry mammography device can use the image system to the greatest extent, and completely solves the problem that the target angle, tube inclination, source image distance and real EFS can all affect the final resolution. rate problem.

Description

technical field [0001] The invention relates to an X-ray imaging device, in particular to a half-view geometry mammography X-ray imaging device. Background technique [0002] With the rapid development of my country's economy, and people's increasing awareness of health. People are paying more and more attention to breast disease and breast health screening. At the same time, the incidence of breast cancer has increased year by year in recent years, and the threat to the life and health of middle-aged and elderly women is increasing. It can be foreseen that mammography machines, especially digital mammography The demand for machines will also increase. In terms of the current development trend of modern hospital construction, digital technology has become the mainstream. The control operation of conventional mammography machines is mainly manual, and the exposure control mode is single. It cannot be set and controlled from the aspects of breast density, thickness, film gra...

AI Technical Summary

Problems solved by technology

The control operation of conventional mammography machines is mainly manual, and the exposure control mode is single. It cannot be set and controlled from the aspects of breast density, thickness, film grayscale, line filter selection, and X-ray dose. Rely on the clinical experience of the examiner to judge, because the clinical experience and level of each doctor are different, it is impossible to accurately and quickly judge the lesion according to the exposed X-ray film, relying on the manual operation of the doctor requires high clinical experience of the doctor, and The working time is long, the process is slow, the quality of X-ray images cannot be guaranteed, the image effect cannot meet the diagnostic requirements, and cannot meet the doctor's judgment on the lesion
