Portable digital radiography detector loss prevention
View Patent ↗A method for managing a portable x-ray detector for an x-ray imaging apparatus registers at least one portable detector with a processor that is associated with the x-ray imaging apparatus. A generated signal is indicative of the location of the registered portable x-ray detector relative to the x-ray imaging apparatus. An alert indication is provided when the generated signal indicates separation of the registered portable x-ray detector from the x-ray imaging apparatus beyond a predetermined distance.
1. A method for managing a portable x-ray detector for an x-ray imaging apparatus, the method comprising:
registering at least one portable detector with a processor that is associated with the x-ray imaging apparatus;
generating a signal that is indicative of the location of the registered portable x-ray detector relative to the x-ray imaging apparatus; and
providing an alert indication when the generated signal indicates separation of the registered portable x-ray detector from the x-ray imaging apparatus beyond a predetermined distance.
2. The method of claim 1 where the alert indication is an audible or visual indication.
3. The method of claim 1 wherein the distance is greater than 20 feet.
4. The method of claim 1 wherein the alert indication is provided by the registered portable x-ray detector or by an operator console.
5. The method of claim 1 where the alert indication is a message that displays at an operator console associated with the x-ray imaging apparatus.
6. The method of claim 1 wherein the x-ray imaging apparatus is a portable x-ray imaging apparatus.
7. The method of claim 6 , where the alert indication is configured to occur as the portable x-ray imaging apparatus moves away from the at least one portable detector or where the alert indication is configured to occur as the at least one portable detector moves away from the portable x-ray imaging apparatus.
8. A portable x-ray imaging apparatus comprising:
a moveable transport frame;
an adjustable support structure coupled to the movable transport frame;
an x-ray source mounted to the adjustable support structure;
at least one portable radiographic detector registered at the portable x-ray imaging apparatus and having an identifier that is coupled to the portable detector; and
an alert indicator at the portable x-ray imaging apparatus, where the alert indicator is configured to operate when the at least one registered portable radiographic detector is greater than a prescribed distance from the mobile x-ray imaging apparatus.
9. The apparatus of claim 8 wherein the alert indicator operates when a wireless communications signal strength drops below a prescribed threshold or when wireless communications from the portable x-ray imaging apparatus to the at least one registered portable radiographic detector is interrupted.
10. The apparatus of claim 8 wherein the alert indicator provides an audible or visual indication.
11. The apparatus of claim 8 wherein the alert indicator operates when the prescribed distance exceeds 20 feet.
12. The apparatus of claim 8 wherein the alert indicator is configured to also occur at the at least one registered portable radiographic detector.
13. An x-ray radiography apparatus comprising:
an x-ray imaging area enclosing at least one x-ray imaging system including an x-ray source;
at least one sensor positioned at an entrance to the x-ray imaging area;
at least one portable radiographic detector registered to the x-ray imaging area; and
an alert indication at the entrance to the x-ray imaging area or at the at least one portable radiographic detector or at an operator console, where the alert indication is configured to operate when the at least one registered portable radiographic detector accesses the entrance to the x-ray imaging area.
14. The apparatus of claim 13 wherein the alert indication is an audible or visual indication.
15. The apparatus of claim 13 wherein an unregistered detector does not trigger the alert.
16. The apparatus of claim 13 , wherein the operator console includes a processor to control operations at the x-ray apparatus and wherein the at least one registered portable radiographic detector is registered at the console.
17. The apparatus of claim 16 wherein the console provides an operator interface that allows an operator to register or to un-register the at least one registered portable radiographic detector.
18. The apparatus of claim 13 wherein the alert indication is not actuated when an authorized person accompanies the at least one portable radiographic detector in accessing the entrance to the x-ray imaging area.
19. A mobile x-ray imaging apparatus comprising:
a moveable transport frame;
an adjustable support structure coupled to the movable transport frame;
an x-ray source mounted to the adjustable support structure;
a sensor that provides a signal that is indicative of the presence or absence of a portable radiographic detector in a transport position on the mobile x-ray imaging apparatus; and
an alert indicator that is configured to operate when the portable radiographic detector is not in the transport position, according to the sensor signal.
20. The apparatus of claim 19 , wherein the portable detector is registered at the mobile x-ray imaging apparatus, the portable detector includes an identifier that is coupled thereto, and wherein the apparatus further comprises an alert indicator that is activated when a wireless communication signal strength between the portable detector and the mobile x-ray imaging apparatus drops below a preselected threshold.
