The Design And Application Of 3D Medical Image Background Processing System Based On PACS

As an information platform for hospital numeralization, PACS (Picture Archiving and Communication System) become more and more important. Currently many hospitals pay much attention to PACS and carry it into execution. According to different hospitals with different scales and needs, PACS can be divided to three types: Full PACS , Department PACS and Mini PACS. PACS always includes information registration, picture viewing, center controlling and other modules. With PACS, doctors can attemper and change information freely, this can improve the hospital's work efficiency and is very convenient for doctors to deal with pictures.With the development of medical imaging device and measurement technique,there are many kinds of medical images. Because of their different imaging principle, they will display different information. Anyway, most of them are 2D not 3D for the solid apparatus. So if we can deal with these images calling for more information, doctors can make diagnosis more accurately. This becomes doctor's urgent need.With computer technical and image information theory, Image background processing technical does much treatment to different images. 2D processing includes many means. Image enhancement just like smoothing and sharpening will wipe off yawp or make edge more clear. Pseudocolor processing will change the gray level image to color image. Segmentation will pick-up and display the interested region of different images. 3D processing includes many kinds of surface rendering and volume rendering. These methods can rebuild a series of 2D medical images to a 3D model which will offer much useful information of anatomical structure. Doctors can get a whole acquaintance to the organ and give a proper cure scheme. Image registration and fusion is a complicated processing technical, It can fuse several pictures into one picture, but it is immature for application for the moment.This paper mainly introduces characteristic and application status of PACS, and then gives a discussion about the image smoothing, image sharpening , pseudocolor processing, image segmentation, 3D reconstruction, image registration and image fusion. It gives out these technical's theory and algorithm. At last we design and implement a 3D medical image background processing software system. This system is based on PACS;itwill provide all kinds of background processing methods. It can help doctors optimize medical images and pick up more useful information. It will improve the diagonosis and treat level.
