Medical Pacs System Database Design Of Cloud Computing

The datebase is the important part of the (Picture Archiving and Communication System,)PACS system,date base document is the basement of program,and the accordance of maintanace.with the increased request ofmedical level,there are many problem,such as,soft and hard unit have past time,the ability of handle and store decreased.the objective of the study is to design a "cloud"which need not buy and update the software,it is to design a "private cloud",it can store and complete the date process.The thesis elaborate the history and the system of PACS.Analyze how the PACS utilize the special structral to cout and storeBecause of the PACS is store the image of CT、MRI、US、DSA et al,and the datum is very arge,so we must to compress it.it is nessory to stuy the compress algorithm.In the thesis anlyze the compress methed with little lost in the DICOM pattern.Then put forward to use the ROI lossless compression and uninteresting to lossy compression combined modality medical image compression.
