Interpretation support apparatus, operation method thereof, and non-transitory computer readable medium
A screen output control unit of an interpretation support server outputs a viewer screen on which a tissue distribution table is displayed. The tissue distribution table has a first axis, a second axis perpendicular to the first axis, and a first bar mark arranged in a region surrounded by the first axis and the second axis. On the first axis, a plurality of parts of the lung are arranged. On the second axis, a plurality of types of tissues are arranged. The first bar mark expresses the volume of the tissue with a length along the first axis.
