Ultrasound diagnostic device for extracting organ contour in target ultrasound image based on manually corrected contour image in manual correction target ultrasound image, and method for same

摘要

An ultrasound diagnostic device includes: a contour extraction unit extracting a first contour image from ultrasound images obtained from spatially-successive examination positions and each including an image of an organ, a contour image indicating a contour of the organ and extracted from the organ image; a specification unit receiving, from a user, specification information specifying a manual correction target ultrasound image and correction information indicating details of a manual correction performed with respect to a first contour image extracted from the manual correction target ultrasound image; and a contour correction unit correcting the first contour image extracted from the manual correction target ultrasound image according to the correction information. The contour extraction unit further extracts a second contour image from a target ultrasound image by using information indicating the corrected first contour image. The target ultrasound image differs from the manual correction target image.
