Abstract
Methods for determining surgical margins using an imaging device are described that use multiple cameras to image a biological sample on a turntable bathed in white light or fluorescing due to a systemically administered dye. Fluorescence farther away from an excitation light source can be compensated upon determining a 3-D position of portions of the sample. The turntable is turned and tilted in order to take enough images to prepare an animation of the sample. In a graphical user interface, the animation can be stopped, zoomed, and tilted per a user's gesture, touch, tablet-tilting, or other commands. The image manipulation can be with touch gestures entered using a sterilizable or disposable touch pen.
