Abstract: A learning model provided in a segmentation device is a learning model which is generated using training data such that segmentation data of a feature region is output when at least one of projection data and reconfiguration data acquired by an imaging device or data derived from the at least one of projection data and reconfiguration data is input.

Abstract: An X-ray CT scanner generates CT imaging information on an imaging region, and has a revolution arm positioning an X-ray generator and an X-ray detector to face one another with a subject therebetween, directing the revolution arm to move so X-ray beam radiation is offset from the center of the imaging region. An axial direction changing mechanism changes an imaging target from a first imaging region to a second imaging region in an axial direction of the imaging central axis, and a controller controls offset CT imaging, and an X-ray imaging information generator to generate first and second CT imaging information based on projection data of the first and second imaging region and to generate a stitch imaging information comprising the first and second CT imaging information.

Abstract: A dental observation device by which, without displaying, in an overlapping manner, a visible light image of an image-capturing site in an oral cavity captured by a 3-D camera and 3-D image information on the image-capturing site in the oral cavity acquired in advance, an invisible portion in the visible light image is easily recognized.
An observation system includes a visible light 3-D camera; a relative position calculator; a 3-D information storage storing 3-D image information acquired in advance; an image display displaying, side by side, a 2-D captured image captured by the visible light 3-D camera and 2-D converted image based on the 3-D image information corresponding to the surgical operation target site; and a display direction adjuster displaying, in the image display, the 2-D converted image in a predetermined direction on the basis of the image-capturing direction detected by the relative position calculator.
