Abstract
An ultrasonic transducer probe is provided which utilizes a pivoting transducer to perform an ultrasonic sector scan. The transducer and its drive mechanisms are contained within a fluid chamber. A portion of the wall of the fluid chamber includes a flexible bellows, which expands and contracts as pressure and temperature changes alter the fluid volume, thereby altering the fluid chamber volume.
