Abstract
In a mechanically scanned ultrasonic probe, an ultrasonic transducer is swingably mounted on a drive shaft which is given a swinging transversal movement and a reciprocating longitudinal movement. The transducer emits an acoustic beam which is steered in a raster format in response to the swing and reciprocating motions. Echos returning from objects contain diagnostic data of a three-dimensional space. All the components are encased in a toothbrush-like housing having a head portion, an intermediate portion and a hand-grip portion. The dual motions are provided by a drive mechanism accommodated in the hand-grip portion and the transducer is accommodated in the head portion. The drive shaft extends through the intermediate portion.
