Moving method for three-dimensional imaging of C-arm X-ray machine

Abstract

The invention relates to a moving method for three-dimensional imaging of a C-arm X-ray machine. The method comprises the following steps: a C-arm of the C-arm X-ray machine is arranged at a limit endof a C slip stroke; a bulb focus emits X-rays for exposure; a horizontal sliding device and a pedestal lifting column of the C-arm X-ray machine move in linkage so as to make a target object locate in an X-ray target angle region; the horizontal sliding device, the pedestal lifting column, the C-arm move in linkage, and the C-arm slides along a C-arm bracket to the other limit end of the C-sliding stroke; in this way, the trajectory of the bulb focus centers the center of the target object and is an arc trajectory having a radius which is the distance between the bulb focus and the center ofthe target object; the bulb stops emitting the X-rays and the exposure ends, so that a three-dimensional image of the target object output by a panel detector is obtained. The invention makes the 3D imaging of the C-arm X-ray machine with a small stroke convenient and fast. The C-arm can be enlarged, so that the imaging range can be enlarged.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a movement method for three-dimensional imaging of a C-arm X-ray machine. Background technique [0002] As one of the most commonly used medical imaging equipment, C-arm X-ray machines are used in patient intervention, orthopedic imaging, trauma, plastic surgery, urology, etc. Traditional C-arm X-ray machines mainly use two-dimensional projection images. With the continuous development of precision and intelligence in the medical field, three-dimensional imaging technology has increasingly become the mainstream of development. Compared with the traditional two-dimensional imaging technology, the 3D reconstruction model not only contains more abundant anatomical structure information such as the external shape of the bone, but also contains multiple useful information inside the bone such as bone density and strength. This technique has broad application prospects in bone biopsy,...

Problems solved by technology

[0004] In order to solve the problem that the sliding stroke of the C-arm of the C-arm X-ray machine is limited, and the line connecting the focal point and the center of the plate does not pass through the center of the C-arm circle, it is difficult to model the 3D image. This invention proposes a three-dimensional imaging of the C-arm X-ray machine. The motion method makes the 3D image modeling based on this motion method simple and effective
