Patent ID: 7110583

Claim:
An ultrasonic diagnostic device that generates and displays an ultrasound image containing an object which is subject to examination in accordance with reflection of ultrasound, said ultrasonic diagnostic device comprising: an automatic contour extracting unit operable to extract a final contour of the object from the ultrasound image by performing a predetermined operation on the ultrasound image; an automatic capacity calculating unit operable to calculate a capacity of the object by using the final contour extracted by said automatic contour extracting unit; and a measurement display unit operable to display the capacity calculated by said automatic capacity calculating unit; wherein said automatic contour extracting unit includes: an initial contour extracting unit operable to roughly extract an initial contour of the object; and a dynamic contour extracting unit operable to accurately extract the final contour by using the initial contour extracted by said initial contour extracting unit as an initial value and by applying an active contour model to the object within the ultrasound image; and wherein said measurement displaying unit is operable to display the capacity while leaving previously calculated capacities displayed so as to display a transition of capacity over time.
