Information processing apparatus and information processing method

摘要

This invention is directed to appropriately searching for case data similar in the process of a disease. A similar case search apparatus (100) according to this invention includes a disease progress model building function of building a disease progress model by extracting feature amounts from a plurality of medical images obtained by imaging the same object in different periods, a unit configured to read out case data, a unit configured to acquire inspection data, a similar case search function of interpolating, by using the model, feature amounts extracted from the plurality of medical images contained in the inspection data, and calculate a similarity between the inspection data and the case data by using the interpolated feature amounts, and a monitor (111) which displays case data selected based on the calculated similarity.

1. An information processing apparatus comprising:
an interpolation unit configured to interpolate, by using an interpolation model, at least either of first feature amounts extracted from a plurality of medical images contained in case data and second feature amounts extracted from a plurality of medical images contained in inspection data; a calculation unit configured to calculate similarities between the plurality of medical images contained in the inspection data and the plurality of medical images contained in the case data by comparing the first feature amounts with the second feature amounts on a display unit; an output unit configured to output case data selected based on the calculated similarities; and a display control unit configured to display an interpolated feature amount, the first feature amounts, and the second feature amounts, wherein the interpolation unit generates, by performing interpolation based on at least either of the first feature amounts and the second feature amounts obtained by an imaging process in actual imaging periods, feature amounts at imaging periods that differ from the actual imaging periods of the medical images, and wherein the display control unit displays the generated featured amounts, the first feature amounts, and the second feature amounts, which are aligned on a time axis on the display unit.
