The specific embodiment
Describe technical scheme of the present invention in detail below in conjunction with accompanying drawing.The embodiment of the invention is only unrestricted in order to technical scheme of the present invention to be described; Although the present invention is specified with reference to preferred embodiment; Those of ordinary skill in the art is to be understood that; Can make amendment or be equal to replacement the technical scheme of invention, and not break away from the spirit and the scope of technical scheme of the present invention, it all should be encompassed in the claim scope of the present invention.
The described system and method for each embodiment of following the present invention is through providing a plurality of little field emission x-ray sources; Carry out realtime imaging in the bimodal art, wherein a plurality of little x-ray sources be distributed in around with flat panel detector over against the arc medial surface of fixing 180 ° of semi arch gantrys in.Fig. 1 is a kind of bimodal Real Time Image System that is used to perform the operation, and this imaging system is made up of hardware and software.Imaging system 1 comprises the support 9 (as: workbench or chaise longue) that is used to carry the experimenter; Support 9 optionally moves up and down and locatees along the axle of workbench; Will be to be positioned at the height and the lengthwise position place of expectation by the experimenter of imaging or inspection, for example: is the center from patient 5 operative site cervical vertebra 7 with the longitudinal axis of imaging system.Workbench comprises pallet 8; This pallet 8 can be parallel to the longitudinal axis that passes fixing circular arc gantry and move, thereby can patient's operative site be moved in the field of view (FOV) of imaging system so that by detector 6 and randomly be carried out to picture by a plurality of x-ray sources and dull and stereotyped CT such as the field emission x-ray source 2 with electronic emitter (not shown).
The patient image data of being surveyed (as: CT data) is received by the work station (not shown), and this work station comprises and is used for suitable hardware and software that carries out image rebuilds etc., is used for the image of on user interface 14, being checked by the operator with generation.
System also comprises data storage 10, and this data storage is coupled to gantry 3, storage raw image data (as: CT data).Data storage is coupled to reconstruction processor 11, and this reconstruction processor is rebuild the image volume of the operative site cervical vertebra 7 that is scanned and represented.In one embodiment, a plurality of image volume of reconstruction processor 11 reconstructions are represented (as: CT data).Then, adopt CT image volume data to proofread and correct the decay in the nuclear image volume data, CT image volume data show individually.
Then, volumetric image data is stored in the volume image memory 12, image volume processor 12 adopts CT image volume data, is used for correcting image volume data decay pattern with generation.Then, on user interface 14, the operator is presented calibrated image volume.In addition, on user interface, show the CT image volume.
2 of x-ray sources across arc be enough, thereby by flat panel detector receive from the X ray of multiple source whole cross-sectional dimension (for example, patient's cervical vertebra, shank ankle joint etc.) across the patient.More particularly; In source 2, adopt the small stationary field-emission X-ray tube; This field-emission X-ray tube at room temperature just can the moment opening and closing, and therefore bigger conventional thermionic emission (operating temperature is greater than 1000 degrees centigrade) is managed the cooling system that requires much less.Field launcher (not shown) on the X-ray tube has switching rate (as: with the order of magnitude of microsecond) fast, and activated X-ray tube can rapid scanning.Be also noted that owing to once have only an X-ray tube for opening, thus each X-ray tube only during the part of total X ray time for opening.For example: in system with 21 X-ray tubes, each X-ray tube only total x-ray bombardment cycle 1/21 during for opening, this makes the cooling simplification of corresponding x-ray source.Yet, also will recognize, although having described limited field emission X, Fig. 1 penetrates source 2, can adopt the field emission source of any suitable quantity.
The field emission X ray need not to cover equably patient's trunk.Or rather, as general opinion, the X ray flux is big more, and the picture quality that can rebuild is high more.Because the corrective surgery position typically is positioned at fixedly center of arc, so advantageously, the X-ray density at center that passes the corrective surgery position of being formed images is higher than periphery.This blocks minimized being avoided simultaneously of patient's radiation dose.In addition, can activate x-ray source according to the size selectivity ground of patient or the body part that is formed images.For example: when the large-scale or adult patient of scanning, can activate whole sources, yet, during scanning small-size or pediatric patient and adult head etc., can the activation center source, and two sidepiece sources maintenances do not activate; Perhaps, when needs scan patients side position, central source does not activate.
The pulse of sending out of the corresponding source sequence of each x-ray source generates successive X-ray scanning band.Simultaneously, corresponding x-ray source has the dutycycle of reduction, and this improves the cooling characteristics of system with respect to the system of routine.
In another embodiment, corresponding x-ray source is (as: 1-2mm of being separated by) pulse alternately, the cooling characteristics that this has reduced local temperature of anode and has further improved system.
Fig. 2 shows the graphic extension of system of the eclipsed visual field of field emission x-ray source 2.Use a plurality of small-sized field emission x-ray sources to replace the X ray of a standard or CT source to reduce cool time to patient's x-ray dose with corresponding field-emission X-ray tube.Image duration x-ray source 2 is connected the very short time at each X ray, thereby consequent fladellum or cone beam are interlocked.At 180 ° fixedly during the circular arc, resulting data can cover corrective surgery position cross section, thereby avoids blocking or use to transmission measurement the needs of 360 ° of tracks.
The placement of several liquid-cooled X-ray tubes receives the obstruction of the spatial constraints at gantry place.In addition, the liquid-cooled pipe is mobile very complicated and quite expensive.To the effective solution of this problem is the fixing layout of field emission x-ray source; Especially the layout of illustrated field emission x-ray source 2 (as: CNT field emission device) among Fig. 2, this layout comprise that several have the placement of the small-sized field-emission X-ray tube of the fixed anode target that switches in a sequential manner.Compare with fixing circular arc anode x ray pipe, because the dose distribution on several x-ray sources and because longer imaging time, the requirement of the anode current in each x-ray source of these x-ray sources is reduced significantly.This allows not have the application of the small stationary anode of liquid cooling system then, to avoid a large amount of thermic loads.
The unlatching of the field emission source of switching fast allows the design of the compactness of such field emission x-ray source.But an advantage of this layout is to switch x-ray source moment, has the X ray pulse in the microsecond scope, thus several field emission x-ray sources 2 and detector acquisition sequence become possibility synchronously.With flexible way the sequence of X ray pulse is programmed, and choosing of the quantity of x-ray source and sequence can be suitable for concrete imaging requirements.In addition, can programme to the dosage of launching from each single source individually, and reduce motion artifact owing to each x-ray source has the very short burst length.Utilize multiple-pulse and accurate triggering programming can satisfy higher dosage requirement.In another embodiment, the motion diagram of gathering As time goes on several projections can provide other control information.
In the computed tomography systems of any kind of, can adopt system 1, wherein, the visual field is because such as the small-sized X-ray detector of flat panel detector 2 and limited.Can adopt system 1 to be used for volume imagery, for example: use the computer tomography of carrying out such as flat panel detector.
