Abstract: A radiation image photographing system includes: a radiation generator installed on a round visit cart or a transportable radiation generator; and an FPD cassette including a plurality of radiation detecting elements arrayed two-dimensionally, wherein the radiation image photographing system performs videography by photographing a sequence of multiple radiation images using the FPD cassette, and the radiation image photographing system further includes: a calculation device configured to calculate remaining time before the photography of the sequence of multiple radiation images is finished; and a display device configured to display the calculated remaining time.

Abstract: An embodiment of an tomographic image generating system may include: an imaging member that includes a radiation source, a radiation detector and a subject table, and captures the projected image a predetermined number of times while changing a positional relationship between the radiation source and the radiation detector; a reconstructing member that generates a tomographic image of the subject from the projected image captured by the imaging member; an acquiring member that acquires a thickness of the subject and/or a two-dimensional shape of a surface of the subject, the surface of the subject being irradiated with radiation; and a controlling member that determines an imaging condition for the imaging member and/or a reconstructing condition for the reconstructing member generating the tomographic image of the subject, on the basis of the thickness and/or the two-dimensional shape of the subject acquired by the acquiring member.

Abstract: A radiation generator capable of projecting radiation includes a light projection apparatus configured to project visible light that indicates, during projection of radiation from the radiation generator, a range including and broader than an irradiation field of radiation projected from the radiation generator.
