A hand-held portable ultrasonic scanning probe for use with energizing and receiving means for imaging sections of a body includes a fluid-filled enclosure coupled to a handle portion which houses a DC drive motor. The output shaft of the drive motor is directly coupled to a level wind drive screw. A holder assembly incorporating a pawl which coacts with the drive screw and a plano-concave transducer moves back and forth across the drive screw as a result of the DC motor output shaft rotation. The linear travel of the transducer creates a linear scan thereby eliminating the diagnostic imaging problems of sector scans.

Portable ultrasonic probe

A heat-sterilizable ultrasonic surgical scanner includes an ultrasonic transducer and a permanent magnet motor for moving the transducer along an arcuate path. The scanner further includes a housing for the ultrasonic transducer and the motor. The housing includes an acoustically transparent window for transmitting ultrasonic energy from and into the housing. A resilient diaphragm permits expension and contraction of a coupling fluid with which the housing is filled without causing fluid loss from the housing due to leakage. The resilient diaphragm is mounted at a location remote from the acoustically transparent window.

Intraoperative scanner

A digital video image splitter permits the top portion of a closed-circuit television (CCTV) display to be shifted right (delayed) or left (advanced) with respect to the stationary bottom portion of the display. The user controls the vertical level (distance from top to bottom of display) at which the split is seen on the display, and the amount of shift from controls in the system. Shifting of the image permits the width of an object displayed on the display to be measured. By matching opposite edges of the object in the display, the width of the displayed object is equal to the amount of shift. A single raster line at the level of the split is available as digitized image intensity data, and represents the intensity profile of the video display, including the object being measured, along that raster line.
