1. A medical image analysis apparatus, comprising: an image data collecting unit configured to collect time-series image data created by each of different medical image diagnostic apparatuses; a tracking condition storing unit configured to store respective tracking conditions corresponding to the different medical image diagnostic apparatuses; a motion parameter measuring unit configured to measure a motion parameter of a biological tissue by processing the time-series image data; a parameter data creating unit configured to create parameter data based on the motion parameter; and a display configured to display the parameter data, wherein the motion parameter measuring unit measures the motion parameter by tracking the time-series image data based on the respective tracking conditions corresponding to the different medical image diagnostic apparatuses, the tracking conditions including at least one of a template size, an observation region, a dynamic range, a gain, and a smoothing process, and by analyzing the image data created by the different medical image diagnostic apparatuses by the use of a common analysis algorithm.
