Mammary gland X-ray machine with composite X-ray filter disc

Abstract

The invention relates to a mammary gland X-ray machine with a composite X-ray filter disc. The mammary gland X-ray machine comprises an X-ray ball pipe, an X-ray image receiver and a visible light source, wherein the X-ray ball pipe is used for transmitting X-rays during exposure; the X-ray image receiver is used for receiving X-rays transmitted by the X-ray ball pipe; and the visible light sourceis used for providing visible light before exposure. The mammary gland X-ray machine is characterized by also comprising an X-ray filter disc, wherein the X-ray filter disc is arranged between the X-ray ball pipe and the visible light source, and is used for filtering the X-rays transmitted by the X-ray ball pipe during exposure; one side facing the visible light source, of the X-ray filter discis subjected to mirror finishing treatment, and is used for reflecting visible light transmitted by the visible light source before exposure, and enabling the light field of the reflected visible light to approximately coincide with the light field of the X-rays. Through the adoption of the mammary gland X-ray machine disclosed by the invention, using a moving device allowing the visible light source to move is avoided, so that the structure of the mammary gland X-ray machine is simplified; and on the basis, the problem that when the moving device is used, the movement is out of control, so that the X-rays are blocked, or a visible light system cannot arrive at a preset position for illumination can also be solved, and the system reliability is improved.

Description

technical field [0001] The invention relates to the technical field of medical imaging equipment, in particular to a mammography machine with a composite X-ray filter. Background technique [0002] In the mammography system, the X-rays are generated from the X-ray tube and adjusted by the X-ray filter to optimize the energy spectrum distribution of the mammary gland. The filter is an indispensable part of mammography and even X-ray imaging. . Filters are usually mounted close to the X-ray focus, near the exit of the tube. [0003] Another must-have component of a mammography system is the visible light illumination system, which provides a visible light field in preparation for breast positioning prior to photography. refer to figure 1 , The visible light lighting system generally consists of a visible light source, a visible light reflector, and a moving device (not shown). When X-ray exposure is used for filming, the visible light illumination system moves out of the X...

Problems solved by technology

This method involves the movement and positioning control of the visible light device. Once the movement control occurs, the visible light system may not be able to reach the predetermined position for lighting, or the visible light system may not move out of the exposure area in time, and the X-ray will be blocked, resulting in the inability to obtain breast images.
