Exposure control based on detector movement
A radiographic imaging system having a number of useable digital radiographic detectors selectively activates one of the detectors to capture a radiographic image. The DR detectors each include a movement detector configured to transmit a movement signal when a movement of the corresponding detector is sensed. A portion of the system is disabled in response to receiving a movement signal transmitted from a motion sensor in a detector other than the active detector.
1. A radiographic imaging system comprising:
an x-ray source; and
a plurality of digital radiographic detectors, the plurality of DR detectors each comprising a motion sensor, each motion sensor configured to transmit a movement signal when a corresponding detector is moved,
wherein the imaging system is configured to designate one of the plurality of DR detectors as an active detector, and wherein the imaging system is further configured to disable activation of the x-ray source in response to the imaging system receiving a movement signal transmitted from a motion sensor corresponding to a detector other than the active detector.
2. The system of claim 1 , wherein the imaging system is further configured to ignore a movement signal transmitted from a motion sensor corresponding to the active detector.
3. The system of claim 1 , wherein the imaging system is further configured to reenable activation of the x-ray source, after activation of the x-ray source is disabled by the imaging system, in response to receiving an operator input requesting that the x-ray source be reenabled.
4. A method of operating an x-ray imaging system, the method comprising:
providing a plurality of DR detectors for use with the x-ray imaging system, the plurality of DR detectors each having a corresponding motion sensor that transmits a movement signal when the motion sensor is moved;
designating only one of the plurality of DR detectors as an active detector; and
disabling the imaging system when a movement signal is received from a motion sensor corresponding to a detector that is not designated as the active detector.
5. The method of claim 4 , further comprising the imaging system ignoring a movement signal transmitted from a motion sensor corresponding to the designated active detector.
6. The method of claim 4 , further comprising reenabling the imaging system, after the imaging system is disabled, in response to receiving an operator input requesting that the imaging system be reenabled.
7. A radiographic imaging system comprising:
a plurality of digital radiographic detectors, the plurality of DR detectors each comprising a motion sensor, each motion sensor configured to transmit a movement signal when a corresponding detector is moved,
wherein the imaging system is configured to designate only one of the plurality of DR detectors as an active detector, and wherein the imaging system is further configured to disable activation of at least a portion of the in aging system in response to the imaging system receiving a movement signal transmitted from a motion sensor corresponding to a detector other than the active detector.
8. The system of claim 7 , wherein the imaging system is further configured to ignore a movement signal transmitted from a motion sensor corresponding to the active detector.
9. The system of claim 7 , wherein the imaging system is further configured to reenable said at least a portion of the imaging system, after said at least a portion of the imaging system is disabled, in response to receiving an operator input requesting that said at least a portion of the imaging system be reenabled.
