Abstract

The invention relates to a breast X-ray radiography system and a pressing device. The pressing device of the breast X-ray radiography system comprises a pressing plate, guide rails and a pressing support, wherein the pressing support supports a pressing plate to move along the guide rails. The pressing device further comprises an electrified brake clutch, a blackout brake clutch, a first transmission, a second transmission mechanism, a lead screw and a lead screw nut, wherein the first transmission mechanism is in the control of the electrified brake clutch, the second transmission mechanism is in the control of the blackout brake clutch, the lead screw is arranged in parallel to the guide rails, and the lead screw nut surrounds the lead screw and is coaxial with the same. The lead screw nut and the pressing support are relatively static along the guide rails, the lead screw nut and the lead screw can relatively rotate, the first transmission mechanism and the lead screw nut are reciprocally driving and driven parts, and the second transmission mechanism and the lead screw are reciprocally driving and driven parts. Pressing action required in the process of breast X-ray radiography can be generated, and more proper pressing actions can be provided.

Description

technical field [0001] The present invention relates to an imaging system, in particular to a compression device of a mammary X-ray photography system and a mammography X-ray photography system equipped with the compression device. Background technique [0002] Currently, mammography systems are widely used in the screening of breast diseases. The mammography system of the prior art generally includes the following components: [0003] Camera frame (integrated high-voltage generator), digital detector, machine head (including X-ray tube and beam limiter), compression device, detector and image processing system; [0004] Among them, the high-voltage generator generates high voltage, and the X-ray tube generates X-rays under high pressure. The X-rays are collimated by the beam limiter and projected to the detector through the object under test. The detector converts the received X-ray signal into Digital signals are processed by an image processing system to form a visible ...
