Abstract
A processor is configured to acquire a plurality of CT images derived by reconstructing a plurality of pieces of projection data having different energy levels, which are acquired by imaging a subject at a plurality of timings, at a plurality of predetermined energy levels, derive visibility information related to visibility of a target region included in each of the plurality of CT images, and determine an image interpretation energy level for interpreting the CT image among the plurality of energy levels based on the visibility information.
Claims17
An information processing apparatus comprising:
- a processor,
- wherein the processor is configured to:
- acquire a plurality of CT images derived by reconstructing a plurality of pieces of projection data having different energy levels, which are acquired by imaging a subject at a plurality of timings, at a plurality of predetermined energy levels;
- derive visibility information related to visibility of a target region included in each of the plurality of CT images;
- and
- determine an image interpretation energy level for interpreting the CT image among the plurality of energy levels based on the visibility information.
An information processing method comprising:
- causing a computer to
- acquire a plurality of CT images derived by reconstructing a plurality of pieces of projection data having different energy levels, which are acquired by imaging a subject at a plurality of timings, at a plurality of predetermined energy levels,
- derive visibility information related to visibility of a target region included in each of the plurality of CT images, and
- determine an image interpretation energy level for interpreting the CT image among the plurality of energy levels based on the visibility information.
A non-transitory computer-readable storage medium that stores an information processing program causing a computer to execute:
- a procedure of acquiring a plurality of CT images derived by reconstructing a plurality of pieces of projection data having different energy levels, which are acquired by imaging a subject at a plurality of timings, at a plurality of predetermined energy levels;
- a procedure of deriving visibility information related to visibility of a target region included in each of the plurality of CT images;
- and
- a procedure of determining an image interpretation energy level for interpreting the CT image among the plurality of energy levels based on the visibility information.
