Abstract: An imaging device capable of acquiring images of an internal structure of a living body highly accurately in a wide range. An imaging device has a first housing to which a proximal portion of an outer sheath is fixed, with a drive shaft for driving a imaging unit and an inner sheath extending through the first housing, and a second housing to which a proximal portion of the inner sheath is fixed and which holds the drive shaft rotatably therein. The first housing has a first port held in fluid communication with an inner lumen of the outer sheath, and the second housing is movable toward and away from the first housing. The imaging device also includes a first gap between the inner sheath and the outer sheath and a second gap between the inner sheath and the drive shaft.

Abstract: An information processing method for assisting a user to be capable of smoothly ascertaining necessary information. An information processing method causes a computer to execute processing for acquiring classification data in which pixels constituting biomedical image data indicating an internal structure of a living body are classified into a plurality of regions including a living tissue region in which a luminal region exists, the luminal region, and an extraluminal region outside the living tissue region, and generating region contour data, in which a portion where a thickness from an inner surface of the living tissue region facing the luminal region exceeds a predetermined threshold is removed from the living tissue region, based on the classification data.
