摘要： Placement of a marker is performed efficiently, when performing a plurality of radiation imaging operations of a subject with different imaging angles. An operator inputs a region of interest within a subject on a bed, via an operating section. The region of interest and a peripheral region thereof are set as an irradiation range, and the marker is placed in the peripheral region. A radiation source control section causes a radiation source to emit radiation toward the subject within the set irradiation range. Radiation which passes through the subject is obtained by a radiation image detector as a radiation image.

摘要： A region of interest information obtaining section obtains the size and position of a region of interest within a radiation image of a subject. A position calculating section calculates positions for a radiation source and a detecting panel that enable appropriate radiation imaging of the region of interest, employing the region of interest information. A moving section moves the radiation source and the detecting panel to the positions calculated by the position calculating section. Radiation images of the subject are obtained while rotating the radiation source and the detecting panel about a rotating axis that passes through a predetermined position at which the subject is placed.

摘要： A tomographic image generation apparatus for generating tomographic images appropriate for diagnosis from radiation images obtained by tomosynthesis imaging. Tomographic images of a subject are generated with a first slice interval by reconstructing a plurality of radiation images obtained by the tomosynthesis imaging. A region of interest is detected from the tomographic images generated with the first slice interval. Tomographic images are generated with a second slice interval, which is smaller than the first slice interval, adjacent to the slice position of a tomographic image from which a region of interest is detected.

摘要： When radiographic images are obtained by radiography using a tomographic image obtainment apparatus, the degree of overlap of anatomical structures of a subject is obtained. Further, a condition of exposure, such as angles θ of radiography, is changed based on the degree of overlap. The angles θ of radiography are angles at which a radiation irradiation unit performs radiography at a plurality of positions to obtain a plurality of radiographic images. The tomographic image obtainment apparatus produces a tomographic image by reconstructing the tomographic image from a plurality of radiographic images obtained by irradiating the subject with radiation from various directions.

The test piece has an insoluble support, through which the test body solution is developed, and a test region formed on the insoluble support, the test region reacting with an analyte in the test body solution and undergoing coloration. A washing liquid is fed to the test region and its neighboring regions at the time between a stage, at which the test body solution has been developed through the test region, and a stage, at which a liquid for amplifying the coloration state of the test region is fed to the test piece, such that the quantity of the washing liquid fed to the test region and its neighboring regions is set to be large as the detected viscosity becomes high.
