Non-isocentric C-shaped arm imaging system imitating G-shaped arm and operation method of non-isocentric C-shaped arm imaging system

Abstract

The invention discloses a non-isocentric C-shaped arm imaging system imitating a G-shaped arm. The non-isocentric C-shaped arm imaging system comprises an imaging device and a control device, the imaging device comprises a chassis part, a mainframe box, a lifting stand column, a horizontal sliding assembly and a C-shaped arm, the mainframe box is installed at the top of the chassis part, and the lifting stand column is installed at the top of the chassis part; and a part of the top of the lifting stand column extends out of the top of the mainframe box, the horizontal sliding assembly is installed at the top of the lifting stand column, the C-shaped arm is installed at one end of the horizontal sliding assembly, a detector and a radiation source are installed on the inner sides of the twoends of the C-shaped arm correspondingly, and deviation angles exist among the detector, the radiation source and a rotation center of the C-shaped arm. The control device comprises an upper computerand a lower computer which are connected to the mainframe box, the signal sending end of the upper computer is connected to the signal receiving end of the lower computer, and the lower computer is incontrol connection with the lifting stand column, the horizontal sliding assembly, the C-shaped arm, the detector and the radiation source.

Description

technical field [0001] The invention relates to the field of imaging systems, in particular to a non-isocentric C-arm imaging system imitating a G-arm and an operating method thereof. Background technique [0002] Intraoperative CT is widely used during the operation and before the end of the operation. It is an imaging tool that can effectively assist doctors in positioning and judgment. At present, the most commonly used intraoperative imaging products are C-arm and G-arm equipment, C-arm equipment It is divided into non-isocentric and isocentric C-arm devices. Non-isocentric and isocentric C-arm devices have the same diameter but larger arcs, which can provide perspective views from more angles; most C-arm devices on the market can be rotated manually C-arm obtains perspective views from different angles, and the operation is relatively cumbersome. Compared with C-arm equipment, G-arm equipment can provide front and side perspective views at the same time, which is more h...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing equipment obtains perspective views at different angles by manually rotating the C-arm, and the operation is relatively cumbersome. The present invention provides a non-isocentric C-arm imaging system imitating a G-arm, which can automatically Arbitrary placement angles to obtain positive and lateral images or images at any angle. While maintaining a large opening and a wide rotation angle of the non-isocentric C-arm, the C-arm is used to rotate forward and backward, the lifting column moves up and down, and the horizontal sliding component is controlled left and right The moving three-axis linkage method realizes the function of imitating the G arm, the structure is simple and easy to use, and it is used to solve the defects caused by the existing technology
