Description
Technical field
The invention belongs to PET membrane technology field, be specifically related to a kind of medical laser colour print imaging PET film and preparation method thereof.
Background technology
Along with clinical medical development, Medical Imaging Technology is being constantly updated and progress, and is playing the part of more and more important role.Such as seven large class subjects such as x-ray diagnostics, CT diagnostics, ultrasonic diagnosis, MR diagnostics, radiotherapeutics, intervention diagnosis and nuclear medicine, basic medical research and clinical diagnose are all played a very important role, and become the indispensable part of medical development.
When Medical Imaging Technology was growing, associated image output system and image forming medium were also constantly promoted thereupon and are improved.The imaging output system has been developed at present dry laser printer and medical image stored digital and the transmission system (PACS) of the most normal use by the wet type laser printer at the beginning of the nineties in last century.Image forming medium has also developed into dry laser printing film and medical dedicated display (soft reading).This two media is as being mainly used at present clinical image display pattern, although aobvious than traditional wet, photographic fixing is different, its operating process is fairly simple, without the discharging of waste liquid.But still Shortcomings part.At first, the unsuitable long preservation of film, in valut, deposit a period of time will turn to be yellow, mildew, it is unfavorable that this will produce when needing again as diagnosis basis in the future, especially after medical-accident-handling rules were implemented, what show was even more important; Secondly, film is lost easily in borrowing process, is damaged, and in a single day some data loses, and damage is with irredeemable; The 3rd, film inquiry, retrieval difficulty are borrowed inconvenience; The 4th, the storage of film needs special-purpose valut place, special messenger's keeping, takies a large amount of spaces and human resources.The 5th, the display that soft reading must be equipped with special-purpose medical high-resolution just can reach the quality requirement that satisfies diagnostic image, and single soft reading can't be satisfied demand and custom that sufferer is changed medical institutions' diagnosis in a short time.
Therefore, on the full-fledged basis of color laser printer, adopt similar paper in the office medium imaged image printing solution as the output system auxiliary in kind of medical image stored digital and transmission system, being applied to medical image image output system becomes a kind of trend, and developed country is applied abroad.This system adopts to meet the color laser printer of medical digital images and communication standard (DICOM) as imaging device, make it seamless integrated with the information network system of hospital, and can meet the image application apparatus connection that DICOM prints out standard with being connected, be applicable to the image printing of various digital medical image equipment, simultaneously, print out task can be distributed to different printers.This print system convenience simple to operation, reduce cost by the consumption of saving film and the liquid medicine of processing accordingly, develop a film, the wearing and tearing of laser camera and developing machine have been reduced simultaneously, prolonged service life of equipment, saved expensive film memory space, and need not safeguard film, reduce the film damage or lost the sky high cost of again printing.Such medium cost low (be equivalent to film 1/5), in Germany, film image cost be 1.6-2.2Euro (Euro), such medium image only need 0.1-0.15Euro (Euro), cost savings surpass 93%; The relatively environmental protection of a whole set of print system, print speed is fast, with film laser printing system phase specific energy Effective Raise operating efficiency.The problems such as image management is convenient, can avoid doctors and patients to look up the illness record in the process, and the film of transfer sheet, borrowing sheet to produce is lost, damage, mistake are put.Solved the contradictory problems of digital management and the image output in kind of hospital's medical image, the actual flow process and the application demand that meet hospital, can fully ensure patients ' interest, be a kind of from working doctor easily and effectively, the multi-angles such as patients ' interest guarantee are set out, the real practical technique that realizes being conducive to hospital and patient.
