Abstract: A computer-implemented method of object enhancement in endoscopy images includes capturing an image of an object within a surgical operative site via an imaging device, determining a size of the object based on the captured image of the object, displaying the captured image of the object, and displaying on the displayed captured image of the object a representation of the determined size of the object.

Abstract: An elevated tray display device comprises a base having upper and lower vertical posts joined in telescoping relation for adjustment of the height and rotational orientation of the upper post and a fastener for affixing the upper post at a selected height and selected rotational orientation. A projecting key-type lug near the top of the post is receivable in a selected one of multiplicity of holes in a tray-mounting plate. The holes are spaced apart along the plate and are in different orientations, thus permitting the plate to be mounted and fastened to the upper end of the post in a selected one of a multiplicity of orientations and locations relative to the post. A tray is mounted on the plate for adjustment of its position to a selected one of an infinite number of locations within spaced-apart limit positions along an axis transverse to the post.
