1. An image processing apparatus comprising:

  • a carotid artery wall estimation unit that acquires ultrasound B-mode images of consecutive frames to estimate a carotid artery wall at a carotid artery minor axis cross section included in an ultrasound B-mode image of a predetermined frame; and

    a heart rate variability tracking unit that uses, as a template image, the ultrasound B-mode image including the estimated carotid artery wall and surrounding tissues of the carotid artery wall and estimates the size of the diameter of the carotid artery wall so as to minimize a margin of error between a transformed template image, which is created by transforming the template image, and the acquired ultrasound B-mode image of each frame, thereby acquiring a time change of the carotid artery wall.
