MIView is an OpenGL based medical image viewer that contains useful tools such as a DICOM anonymizer and format conversion utility. MIView can read DICOM, Analyze/Nifti, and raster images, and can write Analyze/Nifti and raster images. It can also read and convert DICOM mosaic images. The main goal of MIView is to provide a platform to load any type of medical image and be able to view and manipulate the image. Volume rendering is the main type of advanced visualization that I'm trying to implement. With modern graphics cards supporting multiple shader elements, such as the ATI's X850 supporting 12 parallel shading units and NVidia's 8800GT supporting 112 shading units, the ability of current hardware to render computationally intensive scenes is becoming common enough for most users to be able to view volume rendered images in real time.
