Abstract

Technology is described for imaging device (e.g., x-ray detector) that includes a tag reader. In one example, the imaging device includes a imaging matrix of pixel detector elements, a wireless local area network (LAN) transceiver, a tag reader, and a controller. Each pixel detector element is configured to detect photon energy. The wireless LAN transceiver is configured to transmit imaging matrix data to at least one wireless access point (WAP). The tag reader is configured to read WAP configuration data from a close proximity tag. The controller is coupled to the imaging matrix, the wireless LAN transceiver, and the tag reader. The controller is configured to initialize the wireless LAN transceiver for communication with a specified WAP using the WAP configuration data. The at least one WAP includes the specified WAP.

a tag reader configured to read wireless access point (WAP) configuration data from a close proximity tag and to read a control function code from the close proximity tag or a second close proximity tag, wherein the control function code is selected from a group consisting of an image device setting, a reset to default settings command, and combinations thereof;

a controller coupled to the imaging matrix, a wireless local area network (LAN) transceiver, and the tag reader, and configured to initialize the wireless LAN transceiver for communication with a specified WAP using the WAP configuration data and perform a control function on the imaging device based on the control function code; and

the wireless local area network (LAN) transceiver configured to transmit imaging matrix data to the specified WAP after the control function is performed on the imaging device.

2. The imaging device of claim 1 , wherein the tag reader is selected from a group consisting of a near field communication (NFC) reader, a radio-frequency identification (RFID) reader, an optical reader, and a barcode reader.

3. The imaging device of claim 1 , wherein the WAP configuration data is selected from a group consisting of a service set identifier (SSID), an Internet Protocol address (IP address), a passphrase, a country code, a channel, and combinations thereof.

4. The imaging device of claim 1 , further comprising an energy storage component configured to provide power to the imaging device, wherein the energy storage component is selected from a group consisting of a battery and a capacitor.

5. The imaging device of claim 1 , further comprising an indicator configured to provide an indication that the specified WAP is configured for communication with the imaging device, wherein the indicator is selected from a group consisting of a speaker, a light, a light emitting diode (LED), a display, and combinations thereof.

6. The imaging device of claim 1 , wherein the wireless LAN transceiver is configured to communicate using at least one wireless communication standard selected from a group consisting of WiFi, Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, Bluetooth, and IEEE 802.15.

7. The imaging device of claim 1 , wherein the imaging device is a radiation detector, the imaging matrix is a radiation imaging matrix, and each pixel detector element is a radiation pixel detector element configured to detect radiation.

8. The imaging device of claim 7 , wherein the radiation imaging matrix includes a scintillator layer.

9. A method of configuring a portable imaging device for communication with a wireless access point (WAP) using a close proximity tag, the method comprising:

retrieving WAP configuration data from a first close proximity tag by a tag reader on an imaging device, wherein the tag reader on the imaging device is placed within a detectable range of the first close proximity tag;

configuring a wireless local area network (LAN) transceiver to communicate with a WAP associated with the WAP configuration data;

retrieving embedded control function code from one of the first close proximity tag or a second close proximity tag by the tag reader on the imaging device, wherein the tag reader on the imaging device is placed within a detectable range of one of the first close proximity tag or the second close proximity tag, and the embedded control function code is selected from a group consisting of an image device setting, a reset to default settings command, and combinations thereof; and
