X-ray machine

Abstract

The invention discloses an X-ray machine. The X-ray machine comprises a first upright column, a liftable X-ray source assembly, a second upright column, a first flat panel detector, a camera bed, a second flat panel detector and a control device, wherein the X-ray source assembly can rotate around a rotary axis perpendicular to the first upright column, the first flat panel detector is arranged atthe second upright column in a liftable mode, and the second flat panel detector and the first upright column can move along the length of the camera bed; and the control device is connected with both the first flat panel detector and the second flat panel detector, and is used for acquiring a tomosynthesis image of a detection target according to detection signals of the first flat panel detector or the second flat panel detector. During standing detection, the X-ray source assembly and the first flat panel detector move reversely and synchronously, and the X-ray source assembly rotates, sothat the projection image of the detection target is obtained through the first flat panel detector; and during horizontal detection, the first upright column and the second flat panel detector move reversely and synchronously, and the X-ray source assembly rotates, so that the projection image of the detection target is obtained through the second flat panel detector. The X-ray machine has high diagnostic accuracy.

Description

technical field [0001] The present invention relates to the technical field of medical equipment, and more specifically, relates to an X-ray machine. Background technique [0002] In the field of medical imaging technology, DR systems and CT are usually used, and computer technology is used to display medical images in the form of digital images. [0003] However, since the DR system obtains two-dimensional overlapping images, there are layer overlaps and foreign artifacts, and the precision and accuracy of lesion detection are low, which easily leads to missed or misdiagnosed phenomena. [0004] Although CT can obtain tomographic images, the radiation dose of CT inspection is large and the spatial resolution is low. Moreover, CT is prone to artifacts in the inspection of parts of the human body with metal implants, which affects the diagnostic accuracy. [0005] Therefore, how to provide an X-ray machine capable of improving diagnostic accuracy is an urgent problem to be s...
