摘要： A radiation image detector capable of producing an appropriate synchronization signal for reading out image signals from the detector with a simple structure. A synchronization signal generating electrode is provided in parallel with the striped electrode comprised of a plurality of linear electrodes for reading out the radiation image, which is formed such that a section greater than or equal to a threshold size and a section smaller than the threshold size in width in the direction substantially orthogonal to the longitudinal direction of the striped electrode are disposed alternately in the longitudinal direction of the striped electrode, and the sections greater than or equal to the threshold size are disposed in the longitudinal direction at a predetermined pitch. Charges that change cyclically in amount are read out from the radiation image recording section through the synchronization signal generating electrode to generate the synchronization signal.

摘要： In an energetic-beam detection apparatus having a selenium detector which includes a substrate and an energetic-beam absorber being formed on the substrate and containing selenium, a temperature detecting unit detects a temperature of the selenium detector, and a temperature control unit controls the temperature of the selenium detector so that the temperature is maintained in a predetermined range when the selenium detector is in operation. Alternatively, when the temperature of the selenium detector is outside a predetermined range, an operation suppressing unit suppresses the operation of the selenium detector, or a notification unit notifies a user of the deviation of the temperature of the selenium detector from the predetermined range.

摘要： Filmless photon imaging sensor plates and apparatus which are particularly effective in medical radiology and industrial applications including, but not limited to high resolution mammography. In combination, the sensor plates and apparatus provide rapid production of high resolution images which exhibit higher sensitivity and wider dynamic range than contemporary X-ray systems. Novel sensor plate structures provide images having attributes of increased sensitivity; dual plate design providing increased pixel read-out speed and differential dual energy image production; and electrically isolated segments by which a plurality of pixels are read concurrently to reduce overall image processing time. Generally, the plates employ a homogeneous photoconductive material such as amorphous selenium and are read by exposing each pixel sized area to a small diameter scanning light beam. Using light beam scanning, resulting plate design promises low cost manufacture of both sensor plates and associated apparatus. Novel application of electric fields during plate preparation, exposure and read-out provides improved sensor plate performance. A plurality of precisely-positioned light beams are scanned across the sensor through the use of a novel optical system employing an elongated light source disposed within a rotating drum, the drum being generally opaque with a helical transparent pattern which in combination with a series of lenses and a slit provides the plurality of precisely-positioned scanning light beams. By changing slit and beam widths, variable resolution operation is achieved.
