What changed

USPTO issued Patent US12594049B2 to Canon Kabushiki Kaisha for a radiographic imaging apparatus and control method. The invention enables the imaging device to detect incident radiation rays and acquire radiographic images, with a storage unit that retains imaging information when communication with the control apparatus is abnormal (first imaging state). Upon transition to a normal communication state (second imaging state), a communication control unit automatically transmits stored data to the control apparatus.

For medical imaging device manufacturers, this patent establishes Canon's intellectual property rights in radiographic imaging systems with fault-tolerant data transmission capabilities. Competitors developing similar communication-resilient radiographic imaging equipment should review their product designs for potential infringement exposure and consider licensing negotiations or design-around strategies.

Abstract

A radiographic imaging apparatus configured to be able to communicate with a control apparatus includes: a radiation detecting unit configured to detect incident radiation rays to acquire a radiographic image; a storage unit configured to, in a case where radiographic imaging is performed when in a first imaging state, in which a state of communication with the control apparatus is abnormal, store radiographic imaging information from the radiographic imaging; and a communication control unit configured to, upon a transition from the first imaging state to a second imaging state, in which the state of communication with the control apparatus is normal, transmit the radiographic imaging information stored in the storage unit to the control apparatus.
