Method for controlling multiple wireless self-triggering radiographic image sensors in a single exposure
A method for triggering image capture by a group of simultaneously X-ray exposed multiple wirelessly interlinked self-triggering direct radiography (DR) detector assemblies includes the steps of performing an initiation step to identify the group of participating DR detector assemblies prior to X-ray exposure, detecting the X-ray exposure by a first participating DR detector assembly, the first participating DR detector assembly performing a trigger step to signal all participating DR detector assemblies to start image capture.
1. A method for triggering image capture by a group of simultaneously X-ray exposed direct radiography detector assemblies, the method comprising the steps of:
performing an initiation step to identify a group of participating direct radiography detector assemblies that performs a simultaneous image capture prior to X-ray exposure; and
detecting the X-ray exposure by a first direct radiography detector assembly of the group of participating direct radiography detector assemblies; wherein
the first participating direct radiography detector assembly performs a trigger step to signal to all of the group of participating direct radiography detector assemblies to start image capture.
2. The method according to claim 1 , wherein the group of participating direct radiography detector assemblies are arranged in a partially overlapping tiled arrangement.
3. The method according to claim 1 , wherein the method is used in large field of view radiography applications.
4. The method according to claim 1 , wherein the method is used in full-leg full-spine radiography applications.
5. The method according to claim 1 , wherein the signal generated by the trigger step is sent wirelessly, optically, electrically, or acoustically.
6. The method according to claim 1 , further comprising the step of communicating exposure parameters to the group of participating direct radiography detector assemblies during the initiation step.
7. The method according to claim 1 , further comprising the step of alerting the group of participating direct radiography detector assemblies to their participation in a single exposure via a broadcast message.
8. A self-triggering direct radiography detector assembly comprising:
means for wirelessly receiving identification information of a group of participating direct radiography detector assemblies that perform a simultaneous image capture;
means for wirelessly sending a trigger signal to start the simultaneous image capture to the group of participating direct radiography detector assemblies;
means for wirelessly receiving a trigger signal from others of the group of participating direct radiography detector assemblies to start the simultaneous image capture by the direct radiography detector assembly; wherein
in a case that the direct radiography detector assembly detects a start of an X-ray exposure, the means for wirelessly sending the trigger signal to the group of participating direct radiography detector assemblies is activated; or
in a case that another of the group of participating direct radiography detector assemblies detects a start of an X-ray exposure, the means for wirelessly receiving the trigger signal initiates image acquisition by the direct radiography detector assembly.
9. The assembly according to claim 8 , further comprising:
means for wirelessly communicating exposure parameters to the group of participating direct radiography detector assemblies when wirelessly receiving the identification information of the group of participating direct radiography detector assemblies.
