Abstract
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 display screen of the work station (1). The movable type C-shaped arm three-dimensional reconstruction method and device on the basis of the CUDA have the advantages that data transmission speed is high, price is low, and the operation environment is comfortable.
Description
Technical field
The invention belongs to technical field of medical instruments.
Background technology
Movable C-shaped arm X-ray production apparatus is used widely in medical industry, movable C-shaped arm equipment comprise C type frame, gather the image amplifier of image and the work station of ccd video camera and image procossing; C-arm is moved along track around patient's examine or position to be treated, can reduce to patient unnecessary move displacement, reduce the misery of patient, increase work efficiency.
Common movable C-shaped arm is not wait Center, just carrying out, the conversion of position, side time to carry out reorientating operation, C-arm is when pivoting, detection center cannot be kept to immobilize, when carrying out the inspection of different azimuth to the same position of patient, patient must move at any time, has both added review time and irradiation time, also affect check result, reduce work efficiency; Common movable C-shaped arm work station adopts industrial computer mostly, and equipment is heavy, and mobile inconvenient, price comparison is expensive, and because data volume is large, the time of carrying out three-dimensional reconstruction is long, can not satisfy the demand.
CUDA (compute unified device architecture, unified calculation equipment framework) be the completely newly conception for general purpose computer GPU that NVIDIA company released in 2007, make to be absorbed in the GPU superelevation calculated performance date processing of image processor and brand-new software development environment, cast aside former image API mode and directly GPU managed as computing unit and carry out parallel computation, CUDA programming language is the C language environment for general-purpose computations GPU, and application CUDA programming can realize GPU general-purpose computations easily.
Summary of the invention
The object of the invention: the quick three-dimensional reconstructing algorithm and the related device that propose a kind of movable C-shaped arm based on CUDA, adopt movable fixture, work station is separated with movable C-shaped arm to be convenient to move, work station adopts the ordinary PC with CUDA framework to replace industrial computer, low price, CUDA is adopted to carry out FDK quick three-dimensional reconstructing algorithm, save time, C-arm adopts the four-dimensional motorized designs in congruent center simultaneously, electric vertical lifting, horizontal-extending, full angle rotate, and provide comfortable surgical environments to greatest extent.
The technical solution adopted in the present invention: this device comprises work station, gigabit network cable, mobile device and C-arm X-ray production apparatus, movable C-shaped arm X-ray production apparatus comprises C-arm mechanical system, image amplifier, bulb radiographic source; It is characterized in that: the Centers such as C-arm mechanical system employing, rotate 190 degree along isocenter point O and carry out projection data acquisitions, the data collected are transferred on the PC with the work station of CUDA framework through gigabit network cable, after PC receives data for projection, utilize CUDA to carry out FDK quick three-dimensional reconstructing, the faultage image after reconstruction and 3-D view are presented on the display screen of work station.
The invention has the beneficial effects as follows: the present invention adopts movable fixture, work station is separated with C-arm X-ray production apparatus can independently movement, gigabit network cable is adopted to connect between work station and C-arm X-ray production apparatus, data transmission bauds is fast, work station adopts the ordinary PC with CUDA framework to replace industrial computer, low price, adopts CUDA quick FDK three-dimensional reconstruction algorithm, saves time; C-arm adopts the four-dimensional motorized designs in congruent center, and electric vertical lifting, horizontal-extending, full angle rotate, and is just effectively avoiding, position, side will carry out reorientating operation when changing, providing comfortable surgical environments to greatest extent.
