Abstract
A system for visually monitoring the position of a fetal probe in relation to a fetus includes a housing having a longitudinal axis, a first side and a second side, wherein the first and second sides are on substantially opposite sides of the longitudinal axis. An optical imaging assembly is positioned on the housing to visualize along the first side, and a sensor assembly and a spacing mechanism are positioned on a first side of the housing. The spacing mechanism creates a space between the optical imaging assembly and the fetus so as to provide a wide field of view for the optical imaging assembly.
