    • An object of the present invention is to provide a novel medical application for use in regenerative medicine that uses pluripotent stem cells (Muse cells). The present invention provides a cell preparation for treating myocardial infarction, and particularly serious massive myocardial infarction and heart failure associated therewith, that contains pluripotent stem cells positive for SSEA-3 isolated from biological mesenchymal tissue or cultured mesenchymal cells. The cell preparation of the present invention is based on a cardiac tissue regeneration mechanism by which Muse cells are made to selectively accumulate in damaged myocardial tissue and differentiate into cardiac muscle in that tissue as a result of intravenous administration of Muse cells to a subject presenting with the aforementioned disorders.

    • A computer 12 of an image processing apparatus 11 acquires a moving image including a minor axis cross section of a carotid artery and a cross section of surrounding tissues around the carotid artery and estimates, from images of two temporally different frames of the acquired moving image, an optical flow of each point included in an area corresponding to a carotid artery wall and an optical flow of each point included in an area corresponding to the surrounding tissues. Based on the estimated optical flow of each point, the computer 12 calculates an amount of displacement of the carotid artery and the surrounding tissues with respect to a radial direction of the carotid artery depending on a change in internal pressure of the carotid artery. The computer 12 also calculates an amount of displacement of the carotid artery and the surrounding tissues with respect to the radial direction of the carotid artery depending on a change in the internal pressure of the carotid artery based on a theoretical expression obtained by modeling the carotid artery and the surrounding tissues with a two-layer cylinder. The computer 12 calculates the elastic modulus of the carotid artery wall and the elastic modulus of the surrounding tissues so as to minimize a square error between the two calculated amounts of displacement.
    • 图像处理装置11的计算机12获取包括颈动脉的短轴截面和颈动脉周围组织的横截面的运动图像,并从所获取的运动图像的两个时间上不同的帧的图像中估计出运动图像, 包括在对应于颈动脉壁的区域中的每个点的光流和包括在对应于周围组织的区域中的每个点的光流。 基于每个点的估计光流量,计算机12根据颈动脉内压的变化计算颈动脉和周围组织相对于颈动脉径向的位移量。 计算机12还基于颈动脉模型获得的理论表达,根据颈动脉内压的变化计算颈动脉和周围组织相对于颈动脉径向的位移量 和周围组织用双层圆筒。 计算机12计算颈动脉壁的弹性模量和周围组织的弹性模量,以便最小化两个计算的位移量之间的平方误差。
