1. A medical information processing apparatus, comprising:
processing circuitry configured to
acquire a plurality of pieces of volume data obtained through image capturing of a region including a right cardiac ventricle of a subject for a predetermined duration;
set a plurality of first tracking points corresponding to an outline of the right cardiac ventricle in the plurality of pieces of volume data;
receive, from a user, four designated points including an annulus position on a septum side, an annulus position on a sidewall side, an annulus position on a lower wall side, and an annulus position on a supraventricular crest side, among the set plurality of first tracking points;
set a plurality of second tracking points, each corresponding to a position on an annulus having a saddle shape, by interpolating the received designated points through interpolation processing performed along the saddle shape;
estimate motion of tissue of the right cardiac ventricle by tracking positions of the plurality of second tracking points in the plurality of pieces of volume data;
calculate, based on the estimated motion, cardiac ventricle information indicating at least one of wall motion information and volume information related to the right cardiac ventricle;
calculate, based on the positions of the plurality of second tracking points, annulus information indicating a size or shape of an annulus position of a valve related to inflow or outflow of blood current at the right cardiac ventricle; and
output the cardiac ventricle information and the annulus information.
