Analyzing apparatus and analyzing method

Abstract

An analyzing apparatus according to an embodiment includes processing circuitry. The processing circuitry acquires a plurality of time-series medical images. The processing circuitry calculates, for each of image pairs each formed of two medical images included in the medical images, a first index value indicating similarity between image signals in the two medical images. The processing circuitry also calculates, on the basis of a plurality of the first index values calculated for the respective image pairs, a second index value corresponding to a statistical value in a time direction of the first index values.

What is claimed is: 
     
         1 . An analyzing apparatus comprising a processing circuitry configured to:
 acquire a plurality of time-series medical images, and   for each of image pairs each formed of two medical images included in the medical images, calculate a first index value group indicating similarities between image signals in respective positions in one medical image and image signals in respective positions in the other image, and calculate a second index value indicating similarity between the two first index value groups calculated for two image pairs.   
     
     
         2 . The analyzing apparatus according to  claim 1 , wherein the processing circuitry further calculates, on the basis of a plurality of the second index values calculated for the respective image pairs, a third index value corresponding to a statistical value in a time direction of the second index values. 
     
     
         3 . An analyzing method comprising:
 acquiring a plurality of time-series medical images; and   for each of image pairs each formed of two medical images included in the medical images, calculating a first index value group indicating similarities between image signals in respective positions in one medical image and image signals in respective positions in the other image; and   calculating a second index value indicating similarity between the two first index value groups calculated for two image pairs.
