Provided are system, method, program, and recording medium for non-destructively inspecting baggage in which an inspection corresponding to an article to be inspected is performed even when the article overlaps various objects including similar materials, whereby the system, method, program, and recording medium are efficient and do not exhibit any oversight in inspection. The system comprising a belt conveyor by which baggage is transported, a radiation unit that irradiates the baggage with X-rays, an imaging unit that captures X-rays passing through the baggage, an analysis unit by which image information from the imaging unit is analyzed, a display unit by which an image analyzed by the analysis unit is displayed, and a controller that performs a control so that at least part of the article to be sensed is displayed as an object by the display unit when at least part of the article is analyzed.

System for non-destructively inspecting baggage, method for nondestructively inspecting baggage, program, and recording medium

Provided is an apparatus for measuring the thickness, roughness, and morphology index of the mandibular cortical bone using a dental panorama image to assist in the diagnosis of osteoporosis, wherein the thickness, roughness, and morphological index of the cortical bone is measured more accurately and the diagnosis of osteoporosis can be supported more accurately. An osteoporosis diagnostic support apparatus, wherein the apparatus has a contour extraction unit adapted to extract a mandibular contour from an image of a mandibular cortical bone photographed by a photographic apparatus adapted to photograph the mandibular cortical bone and surroundings thereof, a line segment extraction unit adapted to extract line segments from the image of the mandibular cortical bone photographed by the photographic apparatus; and a cortical bone thickness calculation unit adapted to calculate a thickness of the cortical bone based on the extracted mandibular contour and line segments.

Osteoporosis diagnostic support apparatus

Provided are: a device () and a system () for quantitatively calculating bone density by using an X-ray image of a bone pail, in particular, an alveolar bone; and an imaging assisting tool () for accurately and easily performing X-ray imaging of an alveolar bone. This bone density measurement device () comprises: an image display unit () for displaying X-ray images for an imaged bone part and a reference body on the same screen; a reference body density measurement unit () for measuring the density of the displayed X-ray image for the reference body; a bone part density measurement unit () for measuring the density of the displayed X-ray image for the bone part; and a bone density calculation unit () for calculating the hone density of the bone part by comparing the density of the X-ray image for the bone part with the density of the X-ray image for the reference body.

Bone density measurement device, bone density measurement system, and imaging assisting tool

A periodontal disease testing apparatus of the present invention includes: an X-ray CT scanner photographing a portion including a tooth, a gingiva, and alveolar bone within an oral cavity to generate volume data of the portion; region setting means setting a related region of a subject tooth based on the volume data; defining means defining a principal axis of the subject tooth; correcting means correcting the related region so as to align the principal axis of the subject tooth with a normal direction of a cross-section of an X-ray CT image; multi-planar reconstruction image generating means generating a multi-planar reconstruction image of the corrected related region; means for generating developed image and the like transforming a coordinate of the related region to generate a developed image and a rotated image; and navigating means indicating correspondences of a spatial coordinate among the multi-planar reconstruction image, the developed image, and the rotated image.

Periodontal disease testing apparatus and image processing program used therein

In a test for supporting diagnosis of periodontal disease, a test method, whose measurement result has reproducibility and can be an objective index, is achieved and the loss of a tooth is predicted by use of the obtained objective index. A periodontal disease diagnosis supporting device supports diagnosis of periodontal disease by use of a captured three-dimensional image of a tooth part. The device includes a tooth root adhesion degree measuring part for measuring a degree of adhesion between a tooth root and alveolar bone by use of the image. The device further includes a periodontal disease diagnosis supporting part for supporting diagnosis of periodontal disease by use of a measurement result of the measuring part.
