A radiation image detector includes a radiation-image-detector main body and a vacuum container. The radiation-image-detector main body generates charges by irradiation with an electromagnetic wave for recording that carries a radiation image and records the radiation image by accumulating the charges. The vacuum container is sealed to store the radiation-image-detector main body in a vacuum.

A radiation image detector includes a radiation image detector main-body having radiation detection devices for detecting radiation that are at least linearly arranged, a switching output unit having a multiplicity of switch devices, and a dummy circuit unit connected to a switch device that is switched last among the multiplicity of switch devices. The switching output unit sequentially switches columns of the radiation detection devices by the switch devices and sequentially outputs signals detected by the radiation detection devices line by line. Further, after signals are output from the radiation detection devices in a predetermined line, the dummy circuit unit outputs a signal having a magnitude that does not substantially influence signals that will be read out from the radiation detection devices in the following line of the predetermined line.

A breast image obtaining apparatus using a solid-sate detector, or stimulable phosphor panel capable of correctly obtaining image information up to the area closer to the chest wall of a subject. when picking up the image, the solid-state detector is moved to a place close to the side wall of the housing on the chest wall side by the moving means to pick up the image up to the area close to the chest wall, and when reading the image, it is moved to the opposite direction to secure the overrun zone between the side wall of the housing and end of the solid-state detector on the subject side. By completing acceleration or deceleration of the reading light exposure section within this zone, the scanning rate of the reading light exposure section is maintained constant across the entire region of the solid-state detector.

Deterioration of a photoconductive layer is prevented, by suppressing the application of heat during connection of a second electrode with an external terminal. A solid state detector is constituted by: an external terminal, which is electrically connected to a voltage source for applying a recording voltage to the second electrode when recording image information at a charge accumulating portion; and a connecting member formed by a conductive elastic material, of which a first end is fixed to the external terminal, and a second end contacts the second electrode by elastic force.

摘要:
An EL layer is located between a linear electrode and an opposite electrode, which stands facing the linear electrode, either one of the linear electrode and the opposite electrode being constituted of a light transmissive electrode. Electric power is supplied across the EL layer, which is located between the linear electrode and the opposite electrode, via the linear electrode and the opposite electrode. An optical intensity of light radiated out from the EL layer, across which the electric power has been supplied, is detected. The electric power, which is supplied across the EL layer, is controlled such that the thus detected optical intensity and a predetermined optical intensity, which has been set previously, become approximately identical with each other.

An image information detecting apparatus with an image information detecting unit that receives recording light representing image information, and records the image information by storing electric charges generated in the unit by the recording light. The apparatus further includes a wireless communication means operable for transmission to an external device; a wire communication means operable for transmission to the external device through a detachable communication cable; a wire transmission setting means for setting the wire communication means operable for transmission; and a wireless transmission prohibiting means. The wireless transmission prohibiting means prohibits wireless transmission from the wireless communication means when the wire communication means is set operable for transmission by the wire transmission setting means.
摘要:
A radiographic system includes: a first grating; a second grating having a period that substantially coincides with a pattern period of a radiological image formed by radiation having passed through the first grating; a radiological image detector that detects the radiological image masked by the second grating and outputs image data of the detected radiological image, and a control unit that performs a switching between a first mode in which a plurality of imaging is performed with the second grating being positioned at relative positions having different phases with regard to the radiological image and a second mode in which the radiological image detector is driven without radiation exposure. The control unit repeatedly drives the radiological image detector in the second mode until the radiological image detector is in a steady state and shifts to the first mode after the radiological image detector is in the steady state.
