An external control for varying the arithmetic interpolation between adjacent image buffers, coupled with virtual memory techniques, provides a rapid means for an operator to scan through the collected data and select particular "slices" of interest with a relatively small amount of RAM (random-access memory). Imaging data are stored in multiple image buffers 12, each representing a "slice." The user is provided with an external control 10 which varies the arithmetic interpolation between adjacent image buffers by an interpolator 14. At a particular initial setting, the image from buffer number one will be displayed. As the knob is advanced, the displayed image becomes a linear interpolation between buffer number one and buffer number two. Alternatively, the interpolation can take the form of any algorithm desired.
