Classification: CPC G | IPC G

Claim 10:
11. A medical information processing apparatus, comprising:
a storage configured to store therein, for each point of a first frequency space represented by a plurality of pieces of first frequency component data acquired by applying frequency conversion to data inside first regions of interest that are set to a same corresponding region of a plurality of respective medical images of a plurality of subjects, characteristic data representing a statistical characteristic of data values that appear at the point; and
processing circuitry configured to
acquire second frequency component data by applying the frequency conversion to data inside a second region of interest that is set in a medical image to be processed,
compare, for each point of a second frequency space represented by the second frequency component data, a data value at the point with a piece of the characteristic data for which the first region of interest is set to a same region as the second region of interest, and determine, with the statistical characteristic represented by the characteristic data based on an appearance frequency at which the data value appears, a similarity to the characteristic data, and
designate a target area in the second frequency space represented by the second frequency component data, based on a result of the determination.
