Abstract
An ultrasonic scanning device includes an ultrasonic sensor mounted for rotation. The sensor can be automatically oriented in a predetermined reference position from a random position. During a scanning operation the sensor is rotated by incremental angles. The length of the angles is changed after a predetermined time elapse following the initiation of a scanning operation.
Claims6
An ultrasonic scanning apparatus in which the orientation of a movable ultrasonic sensor can be varied, comprising:
- a housing having a pair of first holes spaced along an axis;
- a sensor support member mounted to said housing for rotation relative thereto about said axis, said support member including first and second legs spaced along said axis and facing one another, each of said legs including a second hole aligned with said axis;
- a pair of support shafts each having one end mounted in one of said first holes, and an opposite end mounted in one of said second holes to enable said sensor support member to rotate about said axis relative to said housing;
- an ultrasonic sensor fixedly mounted on said sensor support member;
- a drive mechanism for generating a driving force;
- and
- transmission mechanism connected between said drive mechanism and said sensor support member for transmitting said driving force to said sensor support member to rotate said sensor support member and said sensor mounted thereon.
