Description

A kind of frosted medical film

Technical field

The present invention relates to a kind of medical film, is a kind of frosted medical film specifically.

Background technology

The use of medical film has had the history in more than 100 year, film originally is called salt elargol sheet, film at that time is by x-ray imaging, X ray passes human body imaging on film then, and then by developing and photographic fixing imaging then, price neither be very high, and the price of every film is about 4.5 yuans, and domestic a lot of producers also produce.But because in the mid-90 in last century, external big producer has formulated digital medical image technology standard, it is the DICOM picture and text standard under the PACS system, X ray passes behind the human body no longer to film imaging, but by IP plate (CR), data flat board (DR, DSA), collector (CT) is collected, via computer image is flowed to the dry type camera then, by the dry type camera imaging, need to be about to the view data input medical dry laser camera of imaging, camera laser scanning film then, imaging on film, form final products, film by this mode work is called as the DVB film, and this technology has been used more than ten years, and this technology still is the sensitization technology in fact, or salt elargol sheet, but because the bottleneck of PACS system has been arranged, the producer of our China is out one after another, and new medical DVB film has been monopolized by big factory of external several families.They are respectively Kodak, Fuji, Konica.Also having a producer in addition is exactly the Ai Kefa of Germany, the film of Ai Kefa is not the photographic film of salt silver, what they used is the heat sublimation technology, because they have also grasped the standard of PACS system, so they have also become one of four large manufacturers of domestic monopolization film.Since domestic producer such as Lekai and so on all by shelves outside the competitive scope of digitlization DVB film, so these famous brand producers price do very high, the price of every film has increased to about 22 yuan by 4.5 yuan, the film that China is annual more than 600,000,000 wherein has more than 500,000,000 to be carved up by these external producers.This situation has continued more than ten years so far!

Domestic very early in fact just someone wants to break through this bottleneck, go to break of the monopolization of external big factory to domestic film industry, but all get nowhere, it at first is the transfer problem of software information, DICOM graphics standard under the PACS be different from the general computer system such as BMP, JPG, the universal standards such as PDF, domestic producer can't come out these image transitions at all, so at first, they just come the cut-away view picture by the mode of screenshotss, be that they can't obtain or say and can't change out original distortionless image information, so they just intercept out the image information that shows on the display with other software, screenshotss getable image information be that very big loss of data is arranged, definition declines to a great extent, and can't reach the medical diagnosis standard at all; So product at that time is scarcely successful, from the image source, just failed.Next by about 2006, along with we a lot of returned student engineer's arrival, our domestic switching software that has also had the DICOM image information stream under the PACS has just had the prerequisite that breaks through this blockade this time, and promptly we have had the figure source.But it is how intact these images, break-even printing, will do you also satisfy the necessary definition effect of medical diagnosis film and fast light heat-resisting moisture-proof and anti-retention simultaneously? what at first expect is exactly laser printing technology, because laser printing technology is the printing technique of at present main flow, its speed is fast, the image definition height, and also the material of imaging is an ink powder, the chemical stability of ink powder is very good, and the holding time is also very long.Data at that time are that the laser machine of main flow can print the image of 2400 * 2400DPI! The concrete implication of this numerical value is, per square inch, promptly on 2.54 * 2.54 square centimeters the area, one has 2400 * 2400 some composition diagram pictures, this is a surprising numerical value, because human eyes can only reach about 300 * 300DPI to the resolution capability of image definition, high again, the human basic resolution of eyes is not come out, but the bottleneck of laser machine slowly manifested to come out: at first, the fine definition of laser machine is based upon on the colored basis, and colored unit have 7 looks, so can mix out abundant image information so, and the image of our medical film all is black and white mostly, that is to say that the pictorial element of our medical film has only two, black and white, and paper itself is white, the ink powder that can remove to regulate image has only a kind of, and that is exactly black powder, singly can't print high-quality black white image with a kind of black powder at all.The definition of black white image is different with the resolution standard of coloured image, how many looks what the resolution standard of coloured image was used is, generally be 256 looks or 24 RGBs, and the standard of black white image is a shade of gray, also be called shade of gray, so-called shade of gray promptly is to print function being divided into what steps from black altogether to pure white image, be exactly what GTGs, GTG is represented with several powers of 2, shade of gray such as general printer prints black white image all is 8 GTGs, and promptly he can be printing off 256 different levels from black to game of shuttlecocks.And our human eye is very high for the resolution ratio of GTG, trained people's naked eyes to the high energy of the resolution capability of GTG near 16, and the general shade of gray that uses of medical film all is 12, that is to say, the standard of medical film is that handle is from deceiving to being divided into 4096 levels in vain.But laser printer is said the film that prints the not in place of a lot of details performances arranged, mainly be embodied in following several situations: first, the lung window picture of CT, lung's lung marking of the inside is made up of the equally thin white partially microgroove of a lot of hairs, if the texture chap of lung, represent that then there has been inflammation in lung, even and the film normal person's that our laser machine is printed lung marking seems all can feel a bit thick; The second, the rabat of DR, reason is the same, also is to seem that lung marking is thicker; The 3rd, the malignant tumour probability that lung assembles is distinguished, the patient that lung assembles is a lot, but judge when this assembly is malignant tumour, be whether the periphery of observing this assembly has some carefully as the radial blood vessel of hair, if having, these invasive blood vessels are indicating that this assembly is likely a malignant tumour so, but in the laser technology printing film that uses us, these details just are difficult to find out; The 4th, bone trabecular pathology, bone trabecular pathology also are very trickle, and some variations on weight and image texture can make the doctor judge the approximate state of the state of an illness, and when still printing by our laser machine, these details are not seen yet.Therefore also there is defective in laser printing technology on medical film is printed.

Present medical film two sides all is a shiny surface, and easy generation once goes out many films or an image is printed on two different films when especially walking sheet in printer, will certainly cause the waste of film like this, and not fogging clear.

Summary of the invention
