Claim 0:
1. An ultrasound transducer cap, comprising:
a hollow body with an internal cavity that is adapted to receive an ultrasound transducer, the hollow body comprising:
an ultrasound transducer window disposed along a length of the hollow body that is configured with parallel edges to provide an unblocked line of sight between the ultrasound transducer housed within the hollow body, and a rectal wall;
a plurality of light emitters disposed along a first edge of the parallel edges and a second edge of the parallel edges of the ultrasound transducer window;
a plurality of light detectors disposed along the first edge and the second edge of the ultrasound transducer window;
wherein the plurality of light emitters on the first edge are oppositely disposed to the plurality of light detectors on the second edge and the plurality of light emitters on the second edge are oppositely disposed to the plurality of light detectors on the first edge such that each light emitter of the plurality of light emitters and each light detector of the plurality of light detectors form adjacent and alternating, colinear, matched pairs;
wherein the plurality of light emitters and the plurality of light detectors are in a linear arrangement from a top portion of the ultrasound transducer window to a bottom portion of the ultrasound transducer window forming matched pairs of alternating light emitters and light detectors spaced apart by the ultrasound transducer window;
an ultrasound fiducial located adjacent to at least one light emitter of the plurality of light emitters or at least one light detector of the plurality of light detectors; and
a capacitive electrode disposed on an outer surface of the hollow body.
