  • Patent number: 10413269
    Abstract: A radiographic image photographing system includes: a radiation generating device configured to emit radiation; a radiographic image photographing device including a plurality of radiation detecting elements arranged in a two-dimensional pattern and configured to read signal values from the radiation detecting elements; a dose detecting unit arranged between the radiation generating device and the subject and configured to detect a dose of radiation emitted to the subject; and a control unit configured to control the radiation generating device such that the dose of the radiation emitted to the subject becomes a target dose, wherein the control unit sets a tube current or a mAs value of the radiation generating device such that the dose of the radiation becomes the target dose, and corrects and sets the tube current or the mAs value in a case where a difference occurs between the dose of the radiation detected and the target dose.

  • Publication number: 20170215832
    Abstract: A radiographic image capturing system includes: a medical cart including a radiation generating apparatus emitting radiation and a first chargeable built-in power supply; a portable radiographic image capturing apparatus including radiation detecting elements and a second chargeable built-in power supply; and a control device managing electric energy remaining in the first built-in power supply and in the second built-in power supply, determines availability of charge of the second built-in power supply in the portable radiographic image capturing apparatus with power from the first built-in power supply in the medical cart based on the electric energy remaining in the first built-in power supply, and performs control so as to allow the charge when the charge is determined to be available, and so as not to conduct the charge when the charge is determined to be unavailable.
