Abstract: A probe of an ultrasonic diagnostic apparatus and a method of controlling the same are disclosed. The probe includes a transducer movably disposed inside a housing of the probe, a detector detecting movement of the probe, and a drive unit controlling operation of the transducer in response to an output from the detector. Acceleration of the probe is measured to adjust intensity of a holding current in order to suppress operation of the transducer depending on the acceleration of the probe, so that, if there is no movement of the probe, a low holding current is output to increase a transmission current by suppressing heat generation, thereby improving image quality.

Abstract: An ultrasound probe includes an elongated member having a longitudinal axis and a distal housing; a transducer having a transducing surface, the transducer pivotally disposed in the housing and configured so that the transducing surface is capable of selectively rotating between a first position perpendicular to the longitudinal axis and a second position at least collinear with the longitudinal axis; a transmission unit coupled to the transducer to rotate the transducer between the first and second positions; and a location detector coupled to the transmission unit to provide a signal corresponding to an orientation of the transducer between the first and second positions.
