A medical diagnostic imager (10) reconstructs (96) raw scan data into digital image representations which are stored in a mass storage memory (46) such as DRAM or disk. As the scanner reconstructs the series of images, each digital representation image is transferred to an image VRAM (100) into one of a plurality of selected image areas. A video monitor (24) displays the electronic image representations from the image VRAM in the selected pattern of images, e.g. a 4.times.3 grid of images. The digital image representations are transferred to the image VRAM and displayed on the video monitor as they are generated such that the monitor displays the previously generated images and the most recently generated image as it develops during the reconstruction process. The diagnosing physician selects (104) one of the images and selectively adjusts (110) the window and level of its gray scale. After each of the images has been independently designated and its gray scale independently adjusted, one or more of the adjusted electronic image representations are transferred to a film printer (32) which makes a hard copy film print of the selected image(s). A graphics control (122) and a keyboard (132) enter data into a graphics VRAM (120) and a text VRAM (130), respectively. The electronic diagnostic image, graphics, and text data are merged (138) such that the graphics and text are superimposed on selected portions of the displayed video images.
