APPARATUS FOR DIAGNOSING ULTRASOUND IMAGE FOR MINIMIZING IMAGE ARTIFACT HAVING TOOTH SHAPE, AND METHOD FOR DIAGNOSING SAME

摘要

Disclosed are an apparatus for diagnosing an ultrasound image for minimizing image artifacts having a tooth shape, resulting from a switching movement by a HVMUX, in an ultrasound image, and a method for diagnosing same. The apparatus for diagnosing the ultrasound image, according to one embodiment of the present invention, comprises: a pulse generator unit for generating a pulse in an electric signal; a plurality of transducer elements; a probe for converting the pulse in the electric signal into an ultrasound wave signal and transferring same to an object body through at least one transducer element; a multiplexer (MUX) for sequentially selecting at least one of the plurality of transducer elements, based on different bias voltages which are applied; and a control unit for moving a scan line in accordance with a line density of the transducer elements, and for switching between the different bias voltages every pulse repetition frequency (PRF) when the scan line moves.
