Analysis And Research Of Medical Image Display

As Developing of computer technology, PACS are getting more popular in the hospitals. In the PACS computer devices are used to store,distribute and display medical image .The medical image software is foundation of PACS and have greate influence on quality of a system .Dicom standard is very popular , it provide a platform independent of special manufacture and make building complex image manage system possible .Medical image software also must conform to this standard if it wants to interpret many kinds of medical image. There are three part of DICOM relating to image display :object define ,data coding method, format of image file . This paper first describes the fundaments of Dicom and these part. On the basis of analyse we design and implement a medical image software .This implement has good ablity of extend and conform to DICOM totally .Medical images used as the base of diagnose have rigor demand for quality of display and image perception . But the same image often has different look on the different device (such as file and CRT )?Specially as PACS system get widely usage now, doctors begin to use softcopy device(color CRT, grayscale CRT and so on) to view more images instead of film. But the feature of CRT can widely change. The DICOM standard defines in detail how medical images can be interchanged and stored and is very succeed. Recently two new DICOM extensions attempt to solve this problem: Grayscale Standard Display Function, Grayscale Softcopy Presentation State. They define a comprehensive model for the display of images on softcopy device . Research them, apply in the developing PACS system and have ablity to control image quality and perception . The results show that device characteristic get better use, quality of image display is improved and doctor can get better image perception. Experiment use also show that new extensions have some limits and need to changed .
