The specific embodiment
Please refer to Fig. 1, the sweep type digital X-ray machine of a plurality of pick offs of use among the figure comprises scan detector 210, detector driving device 215, ball tube of X-ray machine 220, high tension generator 230, collimator 240; Scan detector 210 is fixed on the detector driving device 215, and the ball tube of X-ray machine 220 that is connected with high tension generator 230 is provided with collimator 240.
Minimum in order to drop to the radiological dose of X-ray, the shape of collimator 240 will be mated with the shape of scan detector 210 as far as possible.The principle of form fit is very simple, and that is exactly that the X-ray 250 that lets X-ray bulb 220 sent can pass through collimator 240, the neither too much nor too little surface that just in time covers scan detector 210 fully.Sometimes, collimation or consider the precision of scan-synchronized for ease, the X-ray 250 that 240 projections of collimator are gone out also can be suitably than retouching the surperficial more bigger of detector 210.The part that collimator 240 should can not detect X-ray to 210 of scan detectors as far as possible all retaining is fallen, so that reduce the receiving according to radiological dose of patient.
Please refer to Fig. 2, people's volume imaging generally needs 430 millimeters imaging scope.And the size of maximum pick off generally also has only 220 millimeter, so the detector that the sweep type digital X-ray machine uses just needs to use the pick off of two 220 millimeters sizes.
The first sensor 110 and second pick off 111 be complete laid parallel on its long axis direction; And two pick offs are having an overlapping region 130 on the space on its long axis direction, and the size of this overlapping region 130 must be greater than two imaging dead band 131 sums at two pick off two ends.In addition, in order to let two pick offs not collide, the first sensor 110 and second pick off 111 are in the not overlapping region or the gap 135 that can have on its short-axis direction on the space.Overlapping region 135 should be as far as possible not littler for this, preferably approaches zero, as long as first sensor 110 can not run foul of each other with second pick off 111, friction or mutual interference mutually.
Please refer to Fig. 3, when needs use when forming the sweep type digital X-ray machine detector with bigger imaging zone than 220 millimeters also little pick offs, may need three or more pick off.The putting position of these pick offs should satisfy following several condition:
1. many pick offs laid parallel fully;
2. every pick off should have an overlapping region with two pick offs that are adjacent on its long axis direction;
3. the size of this overlapping region should be greater than the imaging dead band sum at two pick off two ends;
4. two pick offs should be in the not overlapping region that has on its short-axis direction on the space;
This size of overlapping region should be more little not good more, preferably approach zero;
6. when using many (even number) pick offs; Per two pick offs make up according to the mode of figure one; And then be incorporated into the one group of pick off that has combined (containing two pick offs) and other one group of sensor groups that has combined together, just can use many (even number) pick offs; As shown in Figure 2;
7. when using many (odd number) pick offs; Per two pick offs are combined into sensor groups according to the mode of figure one, and then are grouped together the sensor groups that has combined (containing two pick offs) and other sensor groups in a like fashion again.At last, be incorporated into the sensor groups that combines and another independent sensor groups together again, just can have used many (odd number) pick offs.
When using more than two pick offs, the condition during two pick offs of above-mentioned the first five condition that the putting position of pick off should satisfy and use is identical.Figure three has shown the situation when using many (even number) pick offs.6 pick offs have been formed three sensor groups that contain two pick offs.After the similar method of sensor groups reuse that we contain two pick offs again to these three combined, we had just obtained a detector that contains the sweep type digital X-ray machine of six pick offs altogether.Certainly, when we need use many (odd number) pick offs, the pick off of a platform independent that as long as we in the end add.
Please refer to Fig. 4, when hoping that sweep type digital X-ray machine detector can have higher detectivity, when using the separate unit pick off be able to not meet the demands, can consider to use two row or above pick offs, shown in figure four.The putting position of pick off should satisfy following several condition:
(1) many pick offs containing of every row laid parallel fully;
(2) many pick offs among every row are end to end;
(3) interval of many pick offs among every row between end to end should be as far as possible little;
(4) whole system contains at least two rows, and every row is contained many pick offs;
(5) a little displacement should be arranged between adjacent two row's pick offs on its long axis direction is previous pick off and the back pick off width in the zone of space coincidence;
(6) this little displacement should be greater than the dead band at the two ends of every pick off and the interval width sum between adjacent two pick offs.
Shown in figure four, system contains two row's pick offs.Last row is made up of row's pick off 310 on two platforms, and following row is made up of row's pick off 320 under two platforms.There is the imaging dead band that can not form images on the both sides of every pick off, shown in 131.Also has a pick off between joining between every pick off and the adjacent pick off at interval, shown in 350.In order to guarantee that two row's pick offs can have no the imaging dead band, between adjacent two row's pick offs should have on its long axis direction a little displacement 380 promptly descend row's pick off with on arrange the transverse width of two pick offs in the zone of space coincidence.And this little displacement 380 should be greater than two dead bands 331 at the two ends of every pick off and space sensor 350 sums between adjacent two pick offs.In addition, between two row's pick offs a little gap 135 should be arranged also on its short-axis direction.Generally speaking, this gap 335 also should be more little good more, is preferably zero.
Certainly, system also can contain the above pick off of two rows.The number of sensors that every row is contained also can be greater than two.In addition, the detector in the present embodiment not only can be used for the sweep type digital X-ray machine, also can be used for the imaging system of other sweep type, as long as change type of sensor.Because these several kinds are promoted obviously, we repeat no more at this.
