other Embodiment approach

[0124] In other embodiments, the relative pose of the marker between the first marker and the second marker can also be calculated based on the first relative pose and the second relative pose, and then combined with the relative pose of the marker, the first The fixed pose and the second fixed pose are transformed to obtain the relative pose of the target.

[0125] In one of the embodiments, since the C-arm is moving during the detection process, furthermore, during the movement of the C-arm to different positions, two-dimensional fluorescence images and image data (or image data and detection data) can be continuously obtained Information), each set of target images can correspond to a set of detection information, and each set of detection information can correspond to determine the relative pose of the target, so:

[0126] Please refer to Image 6 , determine the corresponding relationship between the two-dimensional fluorescence image and the detection information by the...

Abstract

The invention provides a CT three-dimensional image generation method and device and a CT scanning system.The CT three-dimensional image generation method based on a C-shaped arm comprises the steps that a two-dimensional fluorescence image is obtained; the two-dimensional fluorescence image is obtained by detecting a target object on a bed board by the fluorescence detector with the C-shaped arm; acquiring a plurality of groups of detection information, wherein the detection information is used for representing a first relative pose of a first marker relative to the detection equipment and a second relative pose of a second marker relative to the detection equipment; the first marker is arranged on the C-shaped arm, and the second marker is arranged on the bed board; for each group of two-dimensional fluorescence images, determining a target relative pose corresponding to the group of two-dimensional fluorescence images based on the detection information corresponding to the group of two-dimensional fluorescence images; and reconstructing a three-dimensional image of the target object based on the multiple groups of two-dimensional fluorescence images and the target relative pose corresponding to each group of two-dimensional fluorescence images.

Description

technical field [0001] The present invention relates, in particular, to a CT three-dimensional image generation method, device and CT scanning system. Background technique [0002] Computed tomography (CT) is generally performed by a dedicated CT system. However, the cost of the CT system is high, the size is large and it is not easy to move, and it is difficult to use the CT system in surgery. The C-arm type X-ray fluorescence imaging system is a relatively low-cost instrument widely used in hospitals and clinics, and the imaging system is easy to move and can be easily moved to the nursing office or operating room. Patient waiting. Therefore, an image generation system that obtains CT-type three-dimensional image information based on two-dimensional fluorescence data output by a traditional C-arm fluorescence imaging system is widely used in various consulting rooms and operating rooms. [0003] In related technologies, it is common to first place an X-ray opaque target ...
