Ultrasound image capture device and ultrasound image capture method

An ultrasound imager comprising,

• an ultrasound probe configured to transmit an ultrasound wave to an examination target and receive an echo signal reflected from the examination target,
• a signal processor configured to process the echo signal received by the ultrasound probe, and
• a monitor configured to display a processing result from the signal processor,
• the signal processor comprising,
• an operation part configured to estimate blood-flow velocity information from the echo signal, an image former configured to display blood-flow information by mapping, on the basis of the blood-flow velocity information being estimated, and
• an estimator configured to obtain a certainty degree of the blood-flow velocity information displayed by the mapping using a degree of coincidence derived from a first blood-flow velocity calculated from the echo signal according to a tissue velocity method and a second blood-flow velocity calculated from the echo signal according to a Doppler velocity method and based, at least in part, on the obtained certainty degree, determine whether to:
• generate a corrected blood-flow velocity information,
• re-calculate the degree of coincidence based on the corrected blood-flow velocity information, and
• transmit the corrected blood-flow velocity information and the certainty degree to be displayed by the image former, wherein the image former replaces the displayed blood-flow information with the corrected blood-flow information and generates a displayable notification of the re-calculated degree of coincidence, wherein a user prompt is displayed if the degree of coincidence is not within an acceptable range.
