Abstract

A radiation imaging system comprising an imaging apparatus which includes a sensor and is capable of non-contact power reception, a power supplier capable of non-contact power supply to the imaging apparatus and a controller is provided. The imaging apparatus performs a first readout operation of reading out a signal accumulated in a period during which the sensor is irradiated with radiation and a second readout operation of reading out a signal accumulated in a period during which the sensor is not irradiated with radiation. In accordance with a temporal change in the power supplied from the power supplier to the imaging apparatus in a preceding operation of the first and second readout operations, the controller temporally changes the power supplied from the power supplier to the imaging apparatus in a succeeding operation of the first and second readout operations.

Dependent claims

A radiation imaging system comprising a radiation imaging apparatus, which includes a sensor unit for obtaining a radiation image and is capable of non-contact power reception, a power supply apparatus capable of non-contact power supply to the radiation imaging apparatus, and a controller, wherein

the radiation imaging apparatus is configured to perform a first readout operation of reading out, from the sensor unit, a signal accumulated in a period during which the sensor unit is irradiated with radiation, and a second readout operation of reading out, from the sensor unit, a signal accumulated in a period during which the sensor unit is not irradiated with radiation, and
in accordance with a temporal change in the power supplied from the power supply apparatus to the radiation imaging apparatus in a period of a preceding operation, which is the precedingly performed readout operation of the first readout operation and the second readout operation, the controller is configured to temporally change the power supplied from the power supply apparatus to the radiation imaging apparatus in a period of a succeeding operation, which is the succeedingly performed readout operation of the first readout operation and the second readout operation.
