1. An information processing apparatus comprising: one or more processors; and a memory having stored thereon instructions that, when executed by the one or more processors, cause the information processing apparatus to: acquire a tomogram of an object; acquire a reference distance from a reference point to a region of interest in the object; calculate a corresponding distance based on the reference distance and an attribute of the object; specify a place in the tomogram which corresponds to a portion spaced apart from a position of the reference point by the corresponding distance; and generate a composite image by combining the tomogram with information indicating the place; and output the composite image.
