Description
Technical field
The utility model relates to radionuclide imaging technical field, particularly relates to a kind of collimating apparatus with uniform wall thickness and preparation method thereof.
Background technology
In radionuclide imaging technology, especially at CT (computed tomography, CT scan) and SPECT (single photon emission computed tomography, single photon emission computerized tomography) in technology, collimating apparatus is absolutely necessary one of critical component.Collimating apparatus is normally made up of the material with radiation absorption performance, as lead, tungsten etc., which is provided with some collimating apertures and form collimating aperture array, the effect of collimating apparatus stops not along the ray of collimating aperture flight, the ray allowing edge and the collimating aperture on it to fly passes through, and is widely used in core Medical Devices.
Past a lot of collimating apparatus often adopts the manufacture of corrugated plate adhesive technology, is the US Patent No. 3937969 on November 14th, 1974 and authorizes day to be that a kind of that the China's Mainland patent CN03826552.4 on September 3rd, 2008 all provides adopts the bonding technology manufacturing collimating apparatus of corrugated plate as the applying date.
Described corrugated plate is made up of the material with radiation absorption performance, there is some ripple structions, ripple struction described in each comprises a crest and a trough, and with described crest and the spaced ripple rib of described trough, time bonding, crest in adjacent corrugated plate is aimed at crest, and trough is aimed at trough, and collimating aperture is between the crest and crest of two adjacent corrugated plate and between trough and trough.This bonding way is little due to bond area, easily causes bonding instability, corrugated plate is easily come off cause collimator structure to collapse loose.
In order to solve the problem, China's Mainland patent CN03826552.4 provides two kinds of solutions:
(1) between two panels corrugated plate, the straight plate of a slice is placed again, crest on corrugated plate or trough are bonded on this straight plate, two adjacent corrugated plate still crest are aimed at crest, trough is aimed at trough, and collimating aperture is between crest and described straight plate and between crest and described straight plate.Increasing bond area by increasing described straight plate, ensure that the Stability Analysis of Structures of described collimating apparatus.In this technology, wall around each collimating aperture is made up of the crest on corrugated plate or trough and some ripple ribs and the straight plate of part, due to crest or trough bonding with the straight plate of part, and the thickness of crest, trough, ripple rib and straight plate is substantially equal, so the wall thickness around collimating aperture is equal not to the utmost.
(2), time bonding, the crest on different corrugated plate is aimed at trough, and trough is aimed at crest, and collimating aperture is between the crest and trough of two adjacent corrugated plate or between trough and crest.This bonding way is the top surface area at crest place or the top area of trough due to bond area, increases bond area, ensure that the Stability Analysis of Structures of described collimating apparatus.In this technology, wall around collimating aperture is made up of the crest on corrugated plate, trough and some ripple ribs, because crest is aimed at bonding with the trough on another corrugated plate, trough is aimed at bonding with the crest on another corrugated plate, and the thickness of crest, trough and ripple rib is substantially equal, so the wall thickness around collimating aperture is equal not to the utmost.
Adopt corrugated plate adhesive technology to manufacture collimating apparatus technique simple, both can make by hand, be applicable to little cost and produce and the purposes such as experiment, also can mechanization even automated production, be applicable in enormous quantities manufacture.But because the wall thickness of collimating aperture is equal not to the utmost, cause the collimating aperture array skewness on the collimator in collimating apparatus, and then cause the collimation of collimating apparatus to ray uneven, affect the collimating effect of collimating apparatus.
Therefore, for above-mentioned technical matters, be necessary the method for making that a kind of structure improved collimating apparatus and collimating apparatus are provided, to solve problems of the prior art.
