IMAGE DISPLAY DEVICE, AND TISSUE MOBILITY EVALUATION METHOD

摘要

Provided is an image display device having a high precision motion measurement process and a mobility evaluation system in which directional dependency is inhibited. Provided is an image display device equipped with a motion vector measurement unit (18) for measuring the motion of tissue by using chronological image data and for forming a two-dimensional motion vector field, a mobility evaluation unit (19) for subjecting the mobility of the tissue to numerical analysis by using the two-dimensional motion vector field and for evaluating the mobility of the tissue as an image or a graph, and an image synthesis unit (20) for synthesizing information indicating the mobility with the motion vector field or the image data. Moreover, the image display device contains a motion vector measurement process for gradually increasing the measurement accuracy, and a mobility evaluation method in which directional dependency is inhibited.
