Control apparatus, control system, control method, medical imaging apparatus, medical imaging system, and imaging control method for switching imaging modes based on communication state

An imaging control method of a radiation imaging apparatus that includes:

• a radiation sensor, which has a plurality of pixels, for receiving radiation that has passed through an object and generating a digital data, one or more processors, and a memory having instructions stored thereon which when executed by the one or more processor, cause the radiation imaging apparatus to function as an interface for wireless communication with another apparatus and transmit image data based on the digital data read out from the radiation sensor, obtain state information indicating a communication state of the wireless communication, and control driving of the radiation sensor for reading out the digital data from the radiation sensor to generate the image data, the imaging control method comprising:
• obtaining state information indicating a communication state of the wireless communication from, which is information indicating quality of communication state of the wireless communication which is calculated based on at least one of reception intensity of radio receivable by the wireless communication, a communication rate which is an amount of data capable of being transmitted per unit time and is calculated at a time of transmission of data to a transmission destination, or an error rate;
• and
• controlling driving of the radiation sensor,
• wherein the driving of the radiation sensor is controlled so that the driving of the radiation sensor for a moving image capturing operation is started in a case that the state information is equal to or larger than a first threshold obtained by adding a variation range of the communication state to a second threshold corresponding to a communication rate necessary for the moving image capturing operation, and
• wherein the driving of the radiation sensor is controlled so that the driving of the radiation sensor for the moving image capturing operation is maintained in a case that the state information is equal to or larger than the first threshold, or the state information is smaller than the first threshold and the state information is equal to or larger than the second threshold during the moving image capturing operation.
