Abstract

The invention provides point size light illumination in metrology systems for in-situ surgical applications. A metrology method includes the steps of positioning a point source projector at a known distance from a target site, projecting a light beam through a semi-transparent mask, forming a magnified pattern on the target site from the light beam, visually inspecting a portion of the magnified pattern that is formed on the target site, and determining a measurement of the target site based on the known dimensions of the mask pattern, a magnification factor, and the portion of the magnified pattern that is formed on the target site. The light beam diverges from a point and the semi-transparent mask has a mask pattern of known dimensions. The magnified pattern is magnified from the mask pattern by the magnification factor.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of and priority to US Provisional Application Serial No. 61 / 551,961, filed October 27, 2011, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to a method of measuring the size of a target site. More particularly, the present disclosure relates to a method of projecting an image used in measuring the size of a target site. Background technique [0004] Minimally invasive procedures such as laparoscopic, endoscopic and thoracoscopic surgery have many advantages over traditional open surgery. In particular, minimally invasive surgery does not require large incisions, thus reducing discomfort, recovery time, and many of the harmful side effects associated with traditional open surgery. [0005] Minimally invasive procedures are performed through small openings in the patient's skin. These openings may be incisions in th...
