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： An imaging section includes a radiation source that emits radiation, a detecting panel for detecting the radiation, and a rotating section for integrally rotating the radiation source and the detecting panel about a rotating axis. The radiation source and the detecting panel face each other with the rotating axis that passes though a predetermined position interposed therebetween. The imaging section sequentially images a subject placed at the predetermined position while rotating the radiation source and the detecting panel about the rotating axis, and image signals are read out for each imaging operation. A control section refers to a necessary readout region set by a setting section and controls a readout switching means such that image signals recorded in detection pixels within the necessary readout region are read out by a normal readout section, and image signals recorded in other detection pixels are read out by a high speed readout section.

摘要： A motor controller determines a drive speed of a motor for driving a filter such that an area shifting cycle of the filter synchronizes with a cardiac cycle. The filter starts to rotate before radiation emission, and continues to rotate at a constant speed during two successive radiation emissions. An emission controller controls timing of two emissions in accordance with a phase of the filter. The area shifting cycle of the filter and the cardiac cycle are previously synchronized, and thus a high-performance filter switching device for switching or shifting the filter in synchronization with the emission timing becomes unnecessary. Adjusting the area shifting cycle of the filter in accordance with the cardiac cycle realizes two radiation emissions in two successive cardiac cycles. As a result, an exposure time is shortened.
