Abstract

A docking station for one or more x-ray detectors is disclosed and designed to secure an x-ray detector when not in use to limit exposure of an x-ray detector to drops, jars, and other potentially damaging incidents. The docking station may be equipped to regulate the temperature of a stored x-ray detector. Thermal regulation can be achieved passively or actively using convection, conduction, radiation, and other thermal transference principles. The docking station may also include an electronic interface that communicates with a stored x-ray detector such that thermal regulation may be achieved dynamically and responsively. The docking station may be free-standing or wall-mounted. The docking station may be remote from or integrated with an x-ray scanner. The docking station may also be equipped to charge/re-charge batteries of a stored x-ray detector.

Claims

1. An x-ray detector storage device comprising:

a storage bin sized to store at least one x-ray detector; and

a temperature regulator configured to adjust a temperature of a stored x-ray detector to a desired temperature.

2. The x-ray detector storage device of claim 1 wherein the storage bin is configured to store an x-ray detector that is detached form an x-ray scanner.

3. The x-ray detector storage device of claim 1 wherein the storage bin is remote from an x-ray scanner.

4. The x-ray detector storage device of claim 1 wherein the storage bin includes a data port to interface with a stored x-ray detector and route temperature data of the stored x-ray detector to the temperature regulator.

5. The x-ray detector storage device of claim 1 wherein the temperature regulator is configured to effectuate an increase or a decrease in the temperature of the stored x-ray detector to adjust the temperature of the x-ray detector to the desired temperature.

6. The x-ray detector storage device of claim 1 wherein the temperature regulator includes a controller configured to compare the temperature of the stored x-ray detector to the desired temperature and, from the comparison, determine a rate of temperature adjustment needed to bring the temperature of the stored x-ray detector to the desired temperature without placing thermal stress on internal components of the stored x-ray detector.

7. The x-ray detector storage device of claim 1 wherein the temperature regulator includes a thermo-electric cooling device to adjust the temperature of the stored x-ray detector.

8. The x-ray detector storage device of claim 7 wherein the thermo-electric cooling device is a Peltier device.

9. The x-ray detector storage device of claim 1 wherein the temperature regulator includes a compressor for passing compressed air about one or more outer surfaces of the stored x-ray detector.

10. The x-ray detector storage device of claim 1 wherein the temperature regulator includes a closed coolant circuit and a coolant source designed to circulate coolant about the stored x-ray detector.

11. The x-ray detector storage device of claim 1 wherein the temperature regulator includes one or more fans.

12. The x-ray detector storage device of claim 11 wherein the one or more fans is variable speed controllable.

13. The x-ray detector storage device of claim 1 wherein the temperature regulator includes a heat sink constructed to engage a heated surface of the stored x-ray detector.

14. The x-ray detector storage device of claim 1 wherein the storage bin is configured to store multiple x-ray detectors and wherein the temperature regulator is configured to independently adjust a temperature of the multiple x-ray detectors.

15. The x-ray detector storage device of claim 1 further comprising an LED constructed to provide a visual indication that a stored x-ray detector has a temperature substantially equivalent to the desired temperature.

16. An x-ray detector storage apparatus comprising:

a receptacle sized to receive an x-ray detector during non-use of the x-ray detector;

a temperature control interface connected to the receptacle and configured to provide feedback as to a temperature of an x-ray detector when the x-ray detector is disposed within the receptacle;

a thermal exchange system configured to regulate the temperature of an x-ray detector when the x-ray detector is disposed within the receptacle; and

a controller operationally connected to receive the feedback and control the thermal exchange system to reduce a difference between the temperature of an x-ray detector disposed in the receptacle and a desired temperature.

17. The apparatus of claim 16 wherein the thermal exchange system is configured to regulate thermal exchange with an x-ray detector using at least one of convection, conduction, and radiation.

18. The apparatus of claim 17 wherein the thermal exchange system includes one of a forced air exchange, a cold plate, a heat sink, and a thermo-electric cooling device.

19. The apparatus of claim 16 wherein the controller is further configured to control the thermal exchange system to transfer heat to the x-ray detector if the temperature of the x-ray detector is less than a desired temperature for data acquisition and remove heat from the x-ray detector if the temperature of the x-ray detector exceeds a desired temperature for data acquisition.

20. The apparatus of claim 16 configured to be remote from an x-ray scanner.
