Abstract

A portable radiation imaging system (10) includes a radiation source (11), a radiation detector (7), a remote trigger unit (17) that activates the radiation source (11) and the radiation detector (7) to initiate an imaging operation, a computing device (13) that receives and processes image data generated by the radiation detector (7), and a universal power box (UPB) (1) operatively connected to the radiation source, the radiation detector, the trigger unit and the computing device. A first wireless link (50) is established between the UPB (1) and the computing device (13), and a second wireless link (60) is established between the trigger unit (17) and the UPB (1). Under the control of the UPB (1), the trigger unit uses the second wireless link (50) to send a control signal to the radiation source (11) to initiate the radiation operation, and the computing device (13) uses the first wireless link (50) to receive image data from the radiation detector (7). The trigger unit (17) can remotely initiate the radiation operation.

Claims

1. A portable x-ray imaging system, comprising:

a x-ray source configured to irradiate an object with x-ray radiation;

a x-ray detector configured to detect the x-ray radiation passing through the object and to generate image data based on detected x-ray radiation;

a computing device configured to receive and process the image data-generated by the x-ray detector to produce an x-ray image;

a radio frequency (RF) trigger unit configured to emit a trigger signal to remotely initiate a x-ray imaging operation; and

a universal power box having a housing enclosure and configured to receive electric power from an alternate current (AC) power source and/or a direct current (DC) power source and configured to generate DC voltage to power at least one of a first power board, a second power board and a logical interface board disposed as floating boards within the housing enclosure,

wherein the logical interface board includes logical circuitry configured to (a) receive the trigger signal from the RF trigger unit via RF wireless communication, (b) transfer the trigger signal to the x-ray source and to the x-ray detector via wired or wireless communication, (c) receive the image data from the x-ray detector via wired or wireless communication, and (d) transfer the image data received from the x-ray detector to the computing device via digital wireless communication,

wherein, in response to receiving the trigger signal from the RF trigger unit, the logical data interface routes the trigger signal to the x-ray source and to the x-ray detector to initiate the imaging operation, and

wherein the x-ray source, the x-ray detector, the computing device, the universal power box, and the RF trigger unit are configured to be removably housed in a portable housing having the shape of a suitcase.

2. The portable x-ray imaging system according to claim 1, wherein the universal power box includes a first output port configured to supply the trigger signal to the x-ray source via a first cable, and a second output port configured to supply a DC voltage and the trigger signal to the x-ray detector via a second cable.

3. The portable x-ray imaging system according to claim 1, further comprising a wireless bridge operatively connected to the universal power box and a wireless transceiver operatively connected to the computing device,

wherein the logical interface board transfers the image data received from the x-ray detector to the computing device via wireless communication through a wireless communication link established between the wireless bridge and the wireless transceiver.

4. The portable x-ray imaging system according to claim 1, further comprising an RF transceiver operatively connected to the universal power box,

wherein the logical interface board receives the trigger signal from the RF trigger unit via RF wireless communication through an RF wireless link established between the RF transceiver and the RF trigger unit.

5. The portable x-ray imaging system according to claim 1, wherein the RF trigger unit includes a long-range, multi-channel, digitally encoded handheld RF switch.

6. The portable x-ray imaging system according to claim 1, wherein the RF trigger unit is configured to receive notification of a time when the x-ray detector is ready to start detecting the x-ray radiation.

7. The portable x-ray imaging system according to claim 6, wherein the RF trigger unit includes a two-position switch configured to activate the radiation source to emit x-ray radiation only after receiving the notification that the radiation detector is ready to detect radiation.

8. The portable x-ray imaging system according to claim 1, wherein the logical interface board includes logic circuitry configured to control the flow of data such that the trigger signal from the RF trigger unit is transferred to the x-ray source with higher priority than the image data transferred from the x-ray detector to the computing device.

9. The portable x-ray imaging system according to claim 1,

wherein the universal power box communicates with the x-ray source through a first wired link to transfer the trigger signal to the x-ray source via wired communication, and

wherein the universal power box communicates with the x-ray detector through a second wired link to transfer the trigger signal and to receive the image data from x-ray detector via wired communication.

10. The portable x-ray imaging system according to claim 1,

wherein the x-ray source is a battery-powered wireless x-ray generator and the x-ray detector is a battery-powered wireless x-ray detector,

wherein the universal power box communicates with the battery-powered wireless x-ray generator through a third wireless link to transfer the trigger signal thereto via wireless communication, and

wherein the universal power box communicates with the battery-powered wireless x-ray detector through a fourth wireless link to transfer the trigger signal and to receive the image data via wireless communication.

11. The portable x-ray imaging system according to claim 1, wherein the universal power box includes a first input port for connecting to the AC power source and a second input port for connecting to the DC power source, and a plurality of output ports for providing DC voltage to at least one of the x-ray source and the x-ray detector.

12. The portable x-ray imaging system according to claim 1, wherein the x-ray source, the x-ray detector, the computing device, the universal power box and the RF trigger unit are removable from the suitcase, and deployable such that the x-ray source and the x-ray detector are placed at a first location, the computing device is placed at a second location remote from the first location, and the RF trigger unit is operable by a user located remote from the first and second locations.
