Problems solved by technology

First of all, the film should not be stored for a long time. It will turn yellow and become moldy after being stored for a period of time in the film library. This will be unfavorable when it needs to be used as a diagnosis basis in the future, especially after the implementation of the medical malpractice handling method, it is even more important; Secondly, films are easily lost and damaged during the borrowing process, and once some materials are lost, the damage will be irreparable; third, it is difficult to query and retrieve films, and it is inconvenient to borrow; fourth, the storage of films requires a dedicated film warehouse site and special personnel to keep them , takes up a lot of space and human resources
Fifth, soft reading must be equipped with a dedicated medical high-definition display to meet the quality requirements of diagnostic images, and a single soft reading cannot meet the needs and habits of patients who need to change medical units for diagnosis in the short term

Abstract

The invention discloses a medical laser color printing and imaging PET (Polyester) film and a preparation method thereof. The PET film comprises a laser printer powdered ink fixing layer, a bridging layer and a PET film, wherein the bridging layer is arranged between the powdered ink fixing layer and the PET film. The preparation method comprises steps as follows: preparing powdered ink fixing layer paint; carrying out corona treatment on the PET film; coating the PET film by a micro scale of aqueous synthetic emulsion or dispersion adhesive; then drying by hot air, so as to obtain the bridging layer; coating the powdered ink fixing layer paint on the bridging layer; and drying by the hot air, so as to obtain the PET film. The PET film is suitable for printing by a colored laser printer, can output a high-resolution image, and is suitable for being used for showing the details of a medical image. The preparation method is simple and efficient, and is suitable for being used for industrialization.

Description

technical field [0001] The invention belongs to the technical field of PET films, and in particular relates to a medical laser color printing imaging PET film and a preparation method thereof. Background technique [0002] With the continuous development of clinical medicine, medical imaging technology is constantly updated and improved, and plays an increasingly important role. Seven categories of disciplines, such as X-ray diagnostics, CT diagnostics, ultrasonic diagnostics, MR diagnostics, radiotherapy, interventional diagnostics and nuclear medicine, play a very important role in basic medical research and clinical medical diagnosis. And has become an indispensable part of medical development. [0003] With the development of medical imaging technology, the related image output system and imaging media have also been continuously improved and improved. The imaging output system has developed from the wet laser printer in the early 1990s to the most commonly used dry la...
