Research And Development Of Some Kernel Software Of PACS

With the fast development of Information Technology and improvement of the computer application technology, the new generation of information system for medicine has expanded from the separate HIS(Hospital Information System), RIS (Radiology Information System) into the integrate hospital management information system which including patient information, medical image and the management information in medicine. PACS(Picture Archiving and Communication System) is an important part of the integrate hospital management information which represents the upmost level in the application of medical information system.The key technologies of PACS develop rapidly within the recent 15 years. However, there is still many problems left when setting up a genuine PACS such as the image acquisition, lossless compression, image transmission image display, etc.. These technologies play an important role in the PACS.The article analyses some key technologies involved in setting up a PACS. It Introduces the DICOM(Digital Imaging and Communications in Medicine) standard and compare several image acquisition methods; It discusses the importance of image compression in PACS, realizes a lossless compression algorithm based on neutral network by revising a former algorithm, expatiates the principle of JPEG-LS Iossless compression standard which is supported by the DICOM2000 standard; It discusses the medical image transmission mode introduces how to achieve the multi-user image transmission based on the windows component technology and the security technologies used in image transmission; It represents some medical image processing technologies, lists out their basic principle and the corresponding realization method. At last, the Article integrates the WEB technology and PACS technology to put forward an absolute resolution of Telemedicinethe Tele-Medicine System based on Internet?and gives the function chart.
