Abstract

A portable imaging detector and a method for operating the portable imaging detector are provided. The portable imaging detector includes a docking connector having a plurality of docking connector contacts. The method includes measuring a voltage at a first docking connector contact, and determining whether the portable detector is (i) operating in a digital cassette mode or is (ii) installed in either a cassette holder or a charging bin using the measured voltage. A detector state monitoring system is also discussed.

Claims

1. A method of operating a portable imaging detector, the portable imaging detector including a docking connector having a first pair of docking connector contacts, said method comprising:

measuring a voltage across the first pair of docking connector contacts; and

determining whether the portable detector is (i) operating in a digital cassette mode or is (ii) installed in either a cassette holder or a charging bin using the measured voltage.

2. A method in accordance with claim 1 further comprising measuring a resistance across a second pair of docking connector contacts to determine if the portable detector is installed in either the cassette holder or the charging bin.

3. A method in accordance with claim 2 further comprising automatically placing the portable detector in a first mode when the portable detector is determined to be installed in the cassette holder.

4. A method in accordance with claim 2 further comprising automatically placing the portable detector in a second mode when the portable detector is determined to be installed in the charging bin.

5. A method in accordance with claim 2 further comprising:

configuring the portable detector in a first operational state when the measured resistance across the second pair of docking connector contacts is less than a threshold value, and

configuring the portable detector in a second different operational state when the measured resistance across the second pair of docking connector contacts is greater than a threshold value.

6. A method in accordance with claim 1 wherein the docking connector includes a plurality of power contacts, said method further comprising measuring a voltage across at least two of the plurality of power contacts.

7. A method in accordance with claim 1 further comprising transitioning the portable detector from a second mode to a third mode when the portable detector is removed from the charging bin.

8. A method in accordance with claim 1 further comprising transitioning the portable detector from a third mode to a first mode when the portable detector is placed in the cassette holder.

9. A detector state monitoring system comprising:

a docking connector coupled to a portable imaging detector, the docking connector having a first pair of docking connector contacts; and

a processor coupled to the docking connector, the processor programmed to;

determine when the portable detector is (i) operating in a digital cassette mode or is (ii) installed in either a cassette holder or a charging bin based on a voltage measured across the first pair of contacts.

10. A detector state monitoring system in accordance with claim 9 wherein the processor is further programmed to use the measured voltage to determine if the portable detector is being operated independently from its own battery while in the digital cassette mode.

11. A detector state monitoring system in accordance with claim 9 wherein the processor is further programmed to automatically place the portable detector in a second mode when the portable detector is determined to be installed in the charging bin.

12. A detector state monitoring system in accordance with claim 9 wherein the processor is further programmed automatically place the portable detector in a first mode when the portable detector is determined to be installed in the cassette holder.

13. A detector state monitoring system in accordance with claim 9 wherein the processor is further programmed to:

configure the portable detector in a first operational state when the measured resistance across a second pair of docking connector contacts is less than a threshold value, and

configure the portable detector in a second different operational state when the measured resistance across the second pair of docking connector contacts is greater than a threshold value.

14. A detector state monitoring system in accordance with claim 9 wherein the docking connector includes a plurality of power contacts, the detector state monitoring system further programmed to measure a voltage at the plurality of power contacts.

15. A detector state monitoring system in accordance with claim 9 wherein the processor is further programmed to:

transition the portable detector from a second mode to a third mode when the portable detector is removed from the charging bin; and

transition the portable detector from a third mode to a first mode when the portable detector is installed into the cassette holder.

16. A portable X-ray detector comprising:

a detector panel; and

a detector state monitoring system coupled to the detector panel, the detector state monitoring system including a docking connector having a first pair of docking connector contacts, and a processor coupled to the docking connector, the processor programmed to;

determine when the portable detector is (i) operating in a digital cassette mode or is (ii) installed in either a cassette holder or a charging bin based on a voltage measured across the first pair of contacts.

17. A portable X-ray detector in accordance with claim 16 wherein the detector state monitoring system is further configured to measure a resistance at a second docking connector contact to determine if the portable detector is installed in either the cassette holder or the charging bin.

18. A portable X-ray detector comprising:

a detector panel including a first pair of docking connector contacts; and

a processor coupled to the first pair of docking connector contacts, the detector panel wirelessly transmitting information to a remote location when the portable detector is operating in a portable state of operation, and transmitting information over a cable to a remote location when the portable detector is operating in a fixed state of operation, the processor programmed to determine when the portable detector is (i) operating in a digital cassette mode or is (ii) installed in either a cassette holder or a charging bin based on a voltage measured across the first pair of docking connector contacts.

19. A portable X-ray detector in accordance with claim 18 wherein the detector

transitions from a second mode to a third mode when the portable detector is removed from the charging bin, and

transitions from a third mode to a first mode when the portable detector is installed a cassette the cassette holder.
