FIELD: physics.
SUBSTANCE: radiation imaging device for detecting the presence or absence of radiation irradiation and determining a dose of radiation comprises a sensor assembly including a pixel array configured to receive an image signal indicative of detected radiation and a plurality of detection elements arranged in a pixel array and configured to detect radiation; a circuit configured to read an image signal from the sensor assembly, wherein said circuitry processes a first signal for detecting the presence or absence of radiation irradiation, and a second signal for determining the radiation dose. The first signal corresponds to a combination of the signals of the first subset of the plurality of detection elements provided by a joint electrical connection to mentioned circuit and the second signal corresponds to a combination of signals of a second subset of the plurality of detection elements provided by a joint electrical connection to mentioned circuit and the number of discovery elements included in the first subset, greater than the number of detection elements included in the second subset.
EFFECT: increased spatial resolution of the resulting image.
