Abstract
An imaging device includes a body having a first end portion configured to be held in a user's hand and a second end portion configured to direct light onto a surgical margin. The device includes at least one excitation light source configured to excite autofluorescence emissions of tissue cells and fluorescence emissions of induced porphyrins in tissue cells of the surgical margin. A white light source is configured to illuminate the surgical margin during white light imaging of the surgical margin. The device includes an imaging sensor, a first optical filter configured to permit passage of autofluorescence emissions of tissue cells and fluorescence emissions of the induced porphyrins in tissue cells to the imaging sensor, and a second optical filter configured to permit passage of white light emissions of tissues in the surgical margin to the imaging sensor. Systems and methods relate to imaging devices.
