Movable type C-shaped arm three-dimensional reconstruction method and device on basis of CUDA

The invention discloses a movable type C-shaped arm three-dimensional reconstruction method and device on the basis of a CUDA, and belongs to the technical field of medical instruments. The device comprises a work station (1), a kilomega network cable (2), a mobile device (3) and a C-shaped arm X-ray machine (4). The C-shaped arm X-ray machine (4) comprises a C-shaped arm mechanical system (5), an image intensifier (6) and a bulb tube X-ray source (7). The device is characterized in that isocenter design is adopted by the C-shaped arm mechanical system (5), the C-shaped arm mechanical system (5) rotates around an isocenter point O by 190 degrees for carrying out projection data collection, collected data are transmitted to a PC of the work station (1) with the CUDA through the kilomega network cable (2), after the PC receives the projection data, FDK rapid three-dimensional reconstruction is carried out through the CUDA, and reconstructed cross-sectional images and three-dimensional images are displayed on a
