Claim 18:
19. A surgical system used to determine a size of a vessel within a region proximate to a working end of a surgical instrument, comprising:
at least one light emitter disposed at the working end of the surgical instrument;
an array of light sensors disposed at the working end of the surgical instrument opposite the at least one light emitter, the array of light sensors comprising at least one row of light sensors, individual light sensors in the at least one row of light sensors each adapted to generate a signal comprising a non-pulsatile component with a magnitude; and
a controller coupled to the array of light sensors, the controller comprising an analyzer to determine the magnitudes of the non-pulsatile components at the individual light sensors in the at least one row of light sensors, to determine a pair of positions corresponding to a first transition in the non-pulsatile component from a higher magnitude to a lower magnitude and a second transition in the non-pulsatile component from a lower magnitude to a higher magnitude, and to determine a resting outer diameter of the vessel based on a symmetrical non-pulsatile profile according to the pair of positions.
