Ct And Spect Medical Image Fusion Technology Research

As the development of electronic technology and the digitization of medical image, all medical image analysis, such as CT, SPECT, MRI and PET can be handled with by computer, resulting better image and more information. Handling with medical image has become a clinic practical technology. It is also the main function of computer in medical image fields. Although CT image can provide human organ anatomical structure information with high resolution, but its soft issue acuteness can not meet with medical requirements; SPECT can provide utilization concentration profile and function information, but its resolution is neither satisfactory, nor organs' boundary very clear. Therefore, single image has no enough information for medical diagnosis. Combining CT and SPECT will give doctor all-around information about human organ texture and function and enhance diagnosis efficiency. Before putting CT image and SPECT image together, it is necessary to registry. Medical image registry makes use of computer to set up a coordinate system and build a new image mode showing up on screen. By means of the new image mode, doctor can see human organ with high cuteness.The article mainly concerns with the research of medical image processing and aims at medical image co-incidence. It points out the advantages and disadvantages of various medical processing technologies. Combining CT with SPECT medical processing frames, the thesis makes out the system designs, including system top-level construction design, soft ware design and hard ware specific construction design. According to the relative principles, the article makes out the system components and the processing technology. So the medical image processing system can be clearly realized by readers.
