ULTRASONIC DIAGNOSTIC DEVICE

摘要

The objective of the present invention is to improve reproducibility of blood flow velocity measurements. A position information conversion unit (9) converts position information of an ultrasonic probe and/or scanning area of a past ultrasonic scan of a subject into first position information in a predetermined coordinate system, and converts the position information of the ultrasonic probe and/or scanning area of a current ultrasonic scan of the subject into second position information in the predetermined coordinate system. A display unit (8) positions and displays a first marker and a second marker on the basis of the first position information and the second position information, said first marker indicating the ultrasonic probe and/or scanning area of the past ultrasonic scan, and said second marker indicating the ultrasonic probe and/or scanning area of the current ultrasonic scan.
