Abstract
An information processing apparatus obtains a plurality of results by performing energy subtraction processing for each of a plurality of sets which are sets each formed from a plurality of radiation images corresponding to different radiation energies and in which combinations of radiation energies are different, and determines a value of a predetermined parameter used in the energy subtraction processing such that a dispersion between the plurality of results is reduced.
Claims17
An information processing apparatus comprising:
- at least one processor;
- and
- at least one memory storing instructions, which when executed by the processor, cause the information processing apparatus to:
- obtain a plurality of results by performing energy subtraction processing for each of a plurality of sets which are sets each formed from a plurality of radiation images corresponding to different radiation energies and in which combinations of radiation energies are different;
- and
- determine a value of a predetermined parameter used in the energy subtraction processing such that a dispersion between the plurality of results is reduced.
