Radiation imaging apparatus
First Claim
Patent Images
1. A radiation imaging apparatus, comprising:
- a radiation detecting section that generates electric charges when irradiated with radiation which has passed through a subject, to record a radiation image of the subject;
a readout section that reads out radiation image signals that represent the radiation image of the subject from the radiation detecting section;
a confirmation image signal generating section, for generating confirmation image signals that represent a confirmation image having a lower resolution than the radiation image represented by the radiation image signals; and
a wireless communicating section that outputs the radiation image signals and the confirmation image signals as wireless signals;
the wireless communicating section decreasing the signal strength of communications, without completely ceasing communications, during transmission of the confirmation image signals to be lower than the signal strength of communications during transmission of the radiation image signals.

Abstract
The signal strength of communications of a cassette transmitter/receiver is set to be lower during transmission of confirmation image signals, that is, during readout of image signals from a radiation detector, than the signal strength of communications of the cassette transmitter/receiver at times other than during readout of image signals. This suppresses adverse influence imparted onto the image signals by wireless communication, and reduces the amount of noise generated in the image signals.
