Abstract
The invention relates to a CT scanning frame ray shielding protective cover which is composed of high-density materials or composite materials capable of shielding rays effectively or lead glass. The CT scanning frame ray shielding protective cover is characterized in that the protective cover is provided with a front protective cover body (1) and a rear protective cover body (2), the junction of the front protective cover body (1) and the rear protective cover body (2) is overlapped, the front protective cover body (1) and the rear protective cover body (2) are shaped like a horn hole at the scanning vacancy, the front part of the horn hole is a large aperture (5), the rear part of the horn hole is a small aperture (6), the rear part of the small aperture (6) is connected with a CT scanning frame annular scanning area (4) which is not covered by protective cover materials and is the effective ray scanning area, and sliding windows (3) are arranged on the upper front parts, corresponding to a CT scanning frame operation panel, of the two sides of the front protective cover body (1). According to the CT scanning frame ray shielding protective cover, the defects in prior art are overcome, and the CT scanning frame ray shielding protective cover is the ideal CT protective equipment.
Description
Technical field
The present invention relates to a kind of CT scan frame alpha ray shield preventer, be a kind of alpha ray shield protective equipment that can be used for medically Medical CT and check specifically, adopting this device effectively can carry out alpha ray shield protection, is a kind of desirable CT alpha ray shield preventer.
Background technology
CT examination, is widely used in modern medical imaging inspection diagnosis, but, because the X-ray energy used during CT examination is high, pass power strong, X-ray is while obtaining rationally application, also to the non-check point of patient, people and surrounding is accompanied to bring radiation hazradial bundle.For this reason, people take many measures to reduce this harm, as covered plumbous matter protective material etc. for patient, still can not deal with problems, trace it to its cause, one, general protective articles is mainly common X-ray and takes a picture, has an X-rayed caused by protection, and the high-energy ray protection effect used CT is undesirable.Its two, because each hospital work is busy, have no time as patient in real work at all or accompany people to do thoughtful protection.Its three, just generally speaking, CT radiation protection is also just confined to, in room, CT machine place, do shielding protection to room surrounding.Even if like this, also have many CT machine rooms protect do and defective, ambient radiation level exceeds natural background radiation manyfold even tens times.Make doctor and the public be subject to unnecessary irradiation, bring potential risk to public health.We think, exert with it to protect the public, more suitable not as thoroughly dealing with problems root, therefore our design have employed CT scan frame alpha ray shield protective cover, root, exchange optimum protection effect for by minimum cost, solve this problem to greatest extent.
Summary of the invention
The object of the invention is to provide a kind of CT scan frame alpha ray shield protective cover, realizing the technical scheme that the object of the invention takes is: this protective cover maybe can be configured with the composite of effect shielding to ray by highdensity material or lead glass is formed, this protective cover is provided with front protective cover and rear defence guard shield, front protective cover and rear defence guard shield junction overlapped, it is that loudspeaker are poroid that front protective cover and rear protecting cover on scanning vacancy, wherein bellmouth orifice front portion is large aperture, bellmouth orifice rear portion is small-bore, rear portion, small-bore connects CT scan frame ring-type scanning area, the unshielded cover material in this region covers, for effective rays scanning area, do not carry out alpha ray shield.Sliding window is provided with at front protective cover both sides front upper part and CT scan frame guidance panel corresponding position.Described front protective cover and the bottom of rear defence guard shield are respectively equipped with universal wheel, are convenient to protective cover and move.
CT scan frame alpha ray shield protective cover of the present invention compensate for the deficiencies in the prior art, reasonable in design, and structure is simple, and be easy to processing, easy to use, effect is good.It is a kind of desirable CT preventer.There is good application value.

Detailed description of the invention
With reference to accompanying drawing, a kind of CT scan frame alpha ray shield protective cover, this protective cover by highdensity material maybe can to ray be configured with effect shielding composite or lead glass form, this protective cover is provided with front protective cover 1 and rear defence guard shield 2, front protective cover 1 and rear defence guard shield 2 junction overlapped, front protective cover 1 and rear defence guard shield 2 are that loudspeaker are poroid in scanning vacancy, and wherein bellmouth orifice front portion is large aperture 5, and bellmouth orifice rear portion is small-bore 6.Rear portion, small-bore 6 connects CT scan frame ring-type scanning area 4, and the unshielded cover material in this region covers, and is effective rays scanning area, does not carry out alpha ray shield.Sliding window 3 is provided with at front protective cover 1 both sides front upper part and CT scan frame guidance panel corresponding position.Described front protective cover 1 and the bottom of rear defence guard shield 2 are respectively equipped with universal wheel 7, are convenient to protective cover and move.Wherein, front protective cover 1 is near scanning bed side, and CT scan bed is made up of pedestal 8 and bed board 9, rear defence guard shield 2 is for being covered in the part at CT scan frame rear portion, for effectively shielding ray, forward and backward protective cover is an overlapped part in junction, and both form the overall ray mask of CT scan frame.Each protective cover, with universal wheel 7, can be removed easily, so that the maintenance of CT.Front protective cover 1 and rear defence guard shield 2, all according to CT scan frame profile design, are that bellmouth orifice sample designs and produces in scanning vacancy, but do not carry out alpha ray shield in CT scan frame ring-type scanner field region.For easy to operate, be provided with sliding window 3 at front protective cover both sides front upper part and CT scan frame guidance panel corresponding position.This protective cover by highdensity material maybe can to ray be configured with effect shielding composite or lead glass form.CT is in running, surface sweeping bed follow procedure requires to do precession on the one hand, simultaneously, X-ray tube does annular when running up in gantry, the ray produced is only in ring-type scanner field region, the ray signal of being decayed by detector detection scanning, forms CT image through a series of digital-to-analogue conversion and analog digital conversion.Due to the effect of alpha ray shield protective cover, the overwhelming majority is absorbed by protective cover shielding at the outer useless scattered rays of ring-type scanner field and primary radiation, surrounding can not be arrived, also people will be accompanied to cause radiation hazradial bundle to the histoorgan outside scanner field and patient, solve the radiation hazradial bundle produced in CT running to greatest extent.
