Abstract: Systems and methods that enable a client device to control scrolling of image data such as slices of MR or CT images using a scrolling gesture. The gesture may be received from a human interface device, and may be mouse moments, touchpad inputs, game controller movements, trackball movements or a movements on a touch-sensitive display. When a scrolling gesture is received at the client device, a velocity and distance of the swipe may be measured. Based on a relationship of gesture velocity to slice scroll velocity, both fine and course scrolling may be provided through the gesture. Control of document scrolling on the display of a client device is also provided.
