Abstract:
An image display device includes: a display unit; an image extraction unit that extracts a main image group from an image group; an image association unit that associates sub images included in a sub image group not extracted from the image group with main images included in the main image group; and a display control unit that generates a display screen in which the main image group is arranged in a first area along a first direction and the sub images are aligned with each of the main images in a second area along a second direction, and causes the display unit to display the display screen. The display control unit changes the display screen in a mode in which the main image group is moved along the first direction and in a mode in which the main image group and the sub image group are moved along the second direction.
Abstract:
A lumen passability checking device checks whether a capsule medical device configured to be introduced into a gastrointestinal tract of a subject is allowed to pass through the gastrointestinal tract. The device includes: a main body dissolvable by a substance in the gastrointestinal tract; a first layer coating the main body, having an outer diameter substantially equivalent to an outer diameter in a minor axis of the capsule medical device, and being dissolvable by the substance in the gastrointestinal tract; and a second layer coating the first layer and being dissolvable by the substance in the gastrointestinal tract. The first and second layers contain different discriminating materials. The first layer has at least two regions extending along a circumference of a cross section of the first layer, the cross section intersecting with a long axis of the device, a part of each region being thinner than other parts.
