1. A reconstruction apparatus, comprising:
processing circuitry configured to:
obtain acquired raw data that is acquired by a medical image diagnosis apparatus; and
reconstruct, based on the acquired raw data, a final data set that represents a measured physical quantity with a multi-dimensional space defined by a space axis, a time axis, and a component axis, wherein
the processing circuitry is further configured to perform:
reduction processing on first partial data relating to a partial area of an intermediate data set at a current number of iterations to generate noise-reduced second partial data:
error compensation processing to compensate errors in the intermediate data set at the current number of iterations with respect to the acquired raw data; and
optimization processing to reconstruct the final data set by repeating the reduction processing and the error compensation processing until predetermined criteria are met, while moving the partial area.
