Abstract

See full text

A computation apparatus that calculates information of a subject includes: a calculation unit configured to calculate a spatial distribution of a first first-order phase value, a spatial distribution of a second first-order phase value, and a spatial distribution of a first-order measurement target value, by using the subject data; a calculation unit configured to calculate an error correction function including the first first-order phase value and the second first-order phase value as variables, by using information of the spatial distribution of the first first-order phase value, information of the spatial distribution of the second first-order phase value, and information of the spatial distribution of the first-order measurement target value; and a calculation unit configured to calculate information of a spatial distribution of a second-order measurement target value, corresponding to a spatial distribution obtained by correcting the spatial distribution of the first-order measurement target value.
