Abstract: An imaging device having an imaging field of view, the imaging device including at least one illumination port configured to output light for illuminating a target; an imaging sensor to detect light traveling along an optical path to the imaging sensor; and a first movable window positioned upstream of the sensor with respect to a direction of travel of light along the optical path, wherein the first movable window is configured to move into the optical path in a deployed position for modifying light received from the target.

Abstract: A housing unit for an ultrasound system which comprises an ultrasound transducer, a video display, an input device and a removable PC computer. The removable PC may be housed within an enclosure defined by the housing unit. The removable PC may house all of the processor(s) required for control and operation of the ultrasound system. The removable PC may be coupled to and uncoupled from the ultrasound transducer, the video display and the input device using conventional connectors. Such connectors permit users to interchange the removable PC with an updated PC without having to send the ultrasound system to the manufacturer and without requiring the services of a technician.
