    摘要: A drive controller varies a bias voltage applied from a bias supply to a conversion layer based on the presence or absence of binning, that is, for a case of carrying out binning where switching elements are driven on the basis of a plurality of rows at a time by a gate drive circuit, and for a case of carrying out no binning where the switching elements are driven on a row-by-row basis by the gate drive circuit. Therefore, in the case of a fluoroscopic mode for acquiring images with binning, a lowering of a dynamic range can be suppressed. In the case of a radiographic mode with no binning, spatial resolution can be made high. That is, a high dynamic range and high spatial resolution can be optimized according to modes of operation.

    摘要: According to a radiation detector manufacturing method, a radiation detector and a radiographic apparatus of this invention, Cl-doped CdZnTe is employed for a conversion layer, with Cl concentration set to 1 ppm wt to 3 ppm wt inclusive, and Zn concentration set to 1 mol % to 5 mol % inclusive. This can form the conversion layer optimal for the radiation detector. Consequently, the radiation detector manufacturing method, the radiation detector and the radiographic apparatus can be provided which can protect the defect level of crystal grain boundaries by Cl doping in a proper concentration, and can further maintain integral sensitivity to radiation, while reducing leakage current, by Zn doping in a proper concentration.

    摘要: The radiation image pickup apparatus of this invention can obtain an accurate temperature characteristic of dark current noise, the dark current noise being caused by dark current flowing through an X-ray conversion layer, by obtaining dark image signals at varied times for accumulating in capacitors charge signals converted by an X-ray converting layer. Consequently, the noise due to the dark current can be removed with high accuracy by removing periodically acquired offset signals from X-ray detection signals acquired at a time of X-ray image pickup, and correcting variations of the dark current noise due to a difference in temperature between a time of offset signal acquisition and the time of X-ray image pickup, using the temperature characteristic of the dark current noise.
