    摘要: An X-ray imaging apparatus including a sensor unit with a sensor array configured to generate a signal corresponding to X-rays and a sound-production unit configured to make a notification by sound production causes the sound-production unit to execute sound production in response to detection of an event. If an event including a sound-production request occurs during a period including a period of reading out a signal from the sensor array, the X-ray imaging apparatus restricts execution of sound production by the sound-production unit.

    摘要: A radiation imaging apparatus comprising: a scintillator; a plurality of pixels configured to respectively detect light converted by the scintillator from radiation; and a corrector configured to perform a correction process on signal data based on signals output from the plurality of pixels is provided. The corrector is configured to perform a first correction process for acquiring a gain map for gain correction without placing an object, and a second correction process including gain correction using the gain map. Correction processes performed on dotted noise that occur at random both temporally and spatially are different for the first correction process and the second correction process.

    摘要: User-friendliness of a radiation imaging apparatus configured to reset a sensor array is improved. This invention is a radiation imaging apparatus including a two-dimensional sensor array. This apparatus includes a scan control signal generation circuit which controls the reset operation of the two-dimensional sensor array, a row number register which stores the row number of a line currently subjected to the reset operation at the time of detection of radiation irradiation, a scan control signal generation circuit which controls read operation after the completion of the radiation irradiation, and an image processing circuit which interpolates an image, of the image generated based on the signals read by the read operation, which corresponds to a line corresponding to the row number stored in the row number register, by using images of adjacent lines.

    摘要: A refresh control line GR (n) is selected while a read control line GT (n+1) or a read control line GT (n−1), which controls a read switch of a pixel of a semiconductor image sensor array is selected. This configuration allows the read and refresh operations or the refresh and read mode setting operations to be performed simultaneously, and reduces the period for scanning the semiconductor image sensor array.
