Abstract
To provide systems and methods for determining target characteristics during a laser procedure.SOLUTION: A method comprises: a step (i) of obtaining a relationship between (i) the number of pixels associated with a light beam reflected from a target or an object located in proximity to the target on an endoscopic image obtained from a video sensor coupled to an endoscope and (ii) a distance to the target from a tip of the endoscope; a step (ii) of measuring the number of pixels associated with the light beam reflected from the target or the object located in proximity to the target during a procedure; and a step (iii) of, based at least in part on the relationship obtained in the step (i) and the measured number of pixels in the step (ii), determining at least one of a size of the target or a distance to the target from the tip of the endoscope.SELECTED DRAWING: Figure 1A
