Abstract

The invention discloses a sensitization sheet camera-shooting scheme. The sensitization sheet camera-shooting scheme is using a thin sensitization sheet B for replacing an image intensifier adopted by the original medical television system to observe a perspective image; the base of the sensitization sheet B is made of a plastic sheet; a rare-earth element material with a high luminous sensitivity is coated on the thin plastic sheet, and a moistureproof treatment is carried out additionally. The cost of the system can be extremely low, and the image quality can also be ensured.

Description

Sensitizing sheet shooting scheme

Technical field

Patent sensitizing sheet shooting scheme of the present invention, relates to a kind of special Technological improvement plan in irradiation image field.

Background technology

In the field of learning at irradiation image, at the beginning of last century, doctors' X ray, is applied to through human body, utilization the image staying on photographic film, does state of an illness diagnosis.Found afterwards, general photographic film, too low to the luminous sensitivity of X ray, just invent subsequently and brushed on a thin paper with a kind of rare earth element, form the fluorescence coating of thin layer, its luminous sensitivity is higher, and people are just this highly sensitive sensitive paper, called after " intensifier ".In darkroom, technician by two such intensifiers, face to face to putting, an X-ray film in therebetween, is tucked in the black paper bag of a semitight, then exposes, like this, required roentgendosis, just can reduce many.

Nowadays, be accompanied by scientific and technological level ground with rapid changepl. never-ending changes and improvements constantly progressive, people have invented again a kind of CR or the digitized imaging device of DR, but this cover system, still need to be dependent at present import, and its price is quite expensive, is not that general middle and small hospital afford to can bear.Say again, before the past do not invent this CR or DR device, can doctor just not diagnose the state of an illness though it is to have avoided the process of a set of flushing, oven dry? thus, hospital has been equipped with this type systematic, is a kind of behave of losing more than gain eventually! Ministry of Public Health say want " medical reform, medical reform ", cry out shake sky-high price sound, but in actual process, after all, they could not make money hospital from improving medicine valency soon again, just constantly increase by every means inspection item and make money more, allow patient increase more financial burden! It could only use in the machine room of radiology department, does not enter operating room, does not more enter ward and this complete equipment, also has significant limitation in use! But also can not observe the dynamic image in patient body, (for example, with it, cannot carry out gastrointestinal perspective and radiography to patient) so the effect that it can be brought into play is very limited at all, the scope of application " very narrow very narrow ".

But hospital has bought this complete equipment, have to again recoup the investment as early as possible, just allow chest " ask " without any sign, Lai Yuan the patient who examines, each and every one all first clap a chest just, the X-ray of side position gets over.(although this language of seemingly slandering, but this is the most well-known in whole nation, in radiation manufacturing industry, be equivalent in bellwether's large-scale state-owned enterprise, the old expert's who has held a post decades stating outright from the depths of one's heart! )

In order to observe the activity video in patient body, the past is by a kind of rare earth element, and brushing, on a transparent glass plate, sees through this piece glass plate, and doctor just can observe directly the activity video in patient body.But adopted this perspective method, it has an X-rayed dosage used, can not Kai get Tai large, because dosage opened greatly, not only can be unfavorable to patient's health; And for the doctor who observes patient's focus, although image can be more clear, the professional doctors of these radiology department, they will be year in year out for patient has an X-rayed, allow them often accept so heavy dose of ray, can be just too large to their injury.Even if (they have worn ray protective clothing, also do not play great effect) therefore, the doctors in past, in one very long period, be all in black room, to carry out under compulsion pivot operation, the diagnostic work that this just gives doctors, has brought great inconvenience.

The sixties of eighties of last century are arrived, people have invented again a kind of image amplifier, on the input screen in a vacuum device, the cesium iodide rare earth element of brushing one deck ISO, utilize the principle of electron focusing, this photosensitive layer is subject to the fluoroscopic image showing after roentgenization, focusing on a diameter only has an appointment on 1 inch of big or small cutout screen, (by the imaging area on original input screen, narrow down to original nine/once) greatly improved like this its luminosity; Then, then use video camera, aim at this cutout screen of 1 inch, absorb image, after the conversion and amplification of a series of electronic device, be presented on electronic screen, like this, just improve doctors' labor condition, after them, just can under the condition of bright chamber, make pivot operation.If again for it mixes a set of tv remote control system, just doctors can completely no longer contact lonizing radiation.

But the input area of this image amplifier can not do too greatly, otherwise volume is too large, and cost will suddenly rise.General general size, can only accomplish 9 inches comparatively suitable, and the cost of itself is also very high.

Summary of the invention

In view of the above and these shortcomings, this invention, has adopted the sensitizing sheet B that cost is comparatively cheap, replaces expensive image amplifier, (its cost compared with image amplifier, poor to two orders of magnitude! ) as the material of ray conversion.Its area, can be made into the shape of arbitrary size and rectangular dimension, and this is just adapted to the custom of the X-ray that general doctors often saw in the past, and it just can be doctors and diagnoses the state of an illness from now on, and convenience is provided further.

Concrete way is, with a high-resolution ccd video camera, aims at this sensitizing sheet B pickup image, and the effect of its imaging, will be not second to the image quality of image amplifier.And the advantage that it brings is in succession a lot: one, the size of this sensitizing sheet B, area can do greatlyr, the longitudinal size of for example its rectangular area, can be locked in 18 inches, and this is just than the diameter of original image amplifier input face, having gone out greatly one times has a surplus, therefore, its effective synthetic resolution, is also just doubled; Two, because adopted high resolution CCD video camera D, this video camera, can give play to its distinctive advantage in this respect; (while originally adopting image amplifier, though also can adopt this high resolution CCD video camera, but do not have great meaning, because the resolution of image amplifier, can improve) three, by signal conversion and the processing of a series of electronic devices, can also make image local amplify, the fine observation focus of these doctors that are just more convenient for, diagnoses the state of an illness, no longer easily fails to pinpoint a disease in diagnosis such accident.

Mention its economic and social benefit, its " cost performance " is very high, because the cost of these a set of components and parts, and 10,000 yuan of the less thaies of adding up still; Its direct consequence will be that County Hospital and township hospital that the whole nation is all, and the community sanitary station in cities and towns, can afford to purchase.
