Title:
ULTRASONIC DIAGNOSTIC APPARATUS
Document Type and Number:
Japanese Patent JP2016010425
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an improvement technique for forming a flow line utilizing an ultrasonic wave.SOLUTION: A Doppler processing part 30 obtains Doppler information in a living body on the basis of a reception signal of an ultrasonic wave. A velocity vector operation part 40 obtains distribution of the velocity vectors of the blood flow in the living body on the basis of the Doppler information in the living body. A flow line formation part 50 searches for a proper starting point by reversely tracking the blood flow in a reverse direction of the velocity vector from an initial starting point when forming the flow line indicating the blood flow on the basis of the distribution of the velocity vectors and forms the flow line extended from the proper starting point.
