Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, this utility model is described in further detail.
Refer to Fig. 1 to Fig. 4, this utility model embodiment provides a kind of new CT beam scanner system, comprising:
Frame 1, described frame 1 is fixed with the x-ray source 2 of annular, the inner side of described x-ray source 2 is provided with rotating disk, described rotating disk is movably set in frame 1, described rotating disk can rotate along the inner side of x-ray source 2, and described rotating disk is provided with more than one flat panel detector group 3 and collimator 4, and the quantity of described flat panel detector group 3 and collimator 4 is consistent, and each flat panel detector group 3 all aligns with a collimator 4, and each collimator 4 is equipped with the slit that can pass through X-ray.The X-ray that the x-ray source 2 of described annular sends can incide in flat panel detector group 3 through the slit 6 on collimator 4, and the centre normal of each flat panel detector group 3 is all through the focus of the x-ray source 2 of annular.Owing to have employed flat panel detector, it needs rotation 1/3 circular scanning just can complete fault imaging to imaging object, shortens imaging time greatly.
Further, described flat panel detector group 3 is made up of side by side plural flat panel detector.This utility model is worked by multiple flat panel detector simultaneously, improves the collecting efficiency of data for projection, significantly shortens imaging time; If in this utility model, the total quantity of its flat panel detector is n (n>1), and n flat panel detector will carry out work simultaneously, and its shortens imaging time is former 1/n.
Further, be provided with detector position adjustment part between described flat panel detector and rotating disk, described detector position adjustment part is for adjusting the gradient between two flat panel detectors.
Further, described rotating disk is provided with data processing module 5, described data processing module 5 connects with all flat panel detector groups 3, and the initial data for collecting flat panel detector group 3 carries out process and obtains faultage image data, and faultage image data is transferred to outside computer.Include in data processing module 5: FPGA (Field-ProgrammableGateArray, field programmable gate array), because FPGA can carry out parallel computation, it shortens the time of date processing and image reconstruction greatly.And be arranged on rotating disk due to data processing module 5, only faultage image is transmitted between computer from rotating disk to outside, and what transmit between existing CT scanner itself and the computer of outside is initial data, data transmission rate General Requirements at hundreds of M to a few G, it needs special wireless data transmission scheme, technical difficulty is large, and production cost is high.And this utility model the faultage image be through after process that carries out transmitting, its data volume reduces one or two magnitude.Like this, the technology such as the UWB (UltraWideband), the WiFi that make transfer rate relatively low just can be used in CT scanner of the present utility model, greatly reduce technical difficulty and the production cost of data transmission.
Further, the quantity of described flat panel detector group 3 is odd number, and it is greater than one.
Further, described collimator 4 is provided with slit width adjustment part, and described slit width adjustment part is for adjusting the width of the slit 6 of collimator 4.The visual field of this collimator 4 just in time covers the flat panel detector group 3 on opposite, its effect is the outgoing scope of about beam X-ray, only allow it irradiate the search coverage of detector, the X-ray in all the other directions is all collimated device 4 and sponges, and its objective is the radiation dose reducing patient and absorb; And when the small volume of imaging object, the width of the slit 6 of collimator 4 can be reduced as required by slit width adjustment part, allow beam only be covered into picture object area, further reduce the radiation dose that imaging object absorbs.
Further, described detector position adjustment part is connected with mode controller, described mode controller is used for inputting mode of operation, and adjusts the location status of detector position adjustment part according to inputted mode of operation; For three flat panel detectors, when X-ray clapped by needs, it is horizontal that mode controller controls three flat panel detectors, and at this moment this utility model can substitute X-ray machine; And when doing CT imaging, the flat panel detector that mode controller controls both sides bends, towards x-ray source 2 focus.The quantity of X-ray that both sides detector unit are receives can be increased like this, improve the output signal strength of probe unit, increase signal to noise ratio, and then improve the quality of faultage image.Controlled the arrangement mode of flat panel detector by mode controller, making it obtain this utility model can adapt to multiple working condition, substitutes traditional X-ray machine and CT scanner, greatly improves the scope of application of the present utility model.
The eigenresolution (most I is to 0.1mm) of the flat panel detector that this utility model is applied is much better than traditional CT detectors (about 1mm), and this makes the resolution of the CT scanner described by this utility model far away higher than CN102988076A design.Therefore, this utility model not only can replace traditional X-ray machine, and can replace CN102988076A scheme.
