Abstract
Technology described herein can be embodied in a method of displaying a visual representation of a portion of a surgical scene. The method includes receiving data representing information captured using a first sensor of a camera associated with a surgical device, the information being indicative of a first quantity representing an amount of fluorescence emitted from the portion of the surgical scene. The method also includes obtaining information indicative of a second quantity representing an amount of excitation signal causing the fluorescence to be emitted from the portion of the surgical scene, and generating a normalized fluorescence signal as a function of the first quantity and the second quantity. The method further includes generating the visual representation of the portion of the surgical scene based on the normalized fluorescence signal, and presenting the visual representation on a display device associated with the surgical device.
