Abstract

Systems and methods to provide an ultrasound scanner with a display interface are described. An ultrasound system includes an ultrasound scanner having an interface configured to display a visual representation, and a first transceiver configured to communicate over a communication link. The ultrasound system includes a display device having a reader configured to read the visual representation displayed by the ultrasound scanner, and a second transceiver configured to, responsive to the reader reading the visual representation, initiate communication with the first transceiver of the ultrasound scanner over the communication link to pair the ultrasound scanner and the display device.

First claim

What is claimed is:

1. An ultrasound system comprising:
a display device; and
an ultrasound probe having an interface configured to display a visual representation comprising a first light representing first data to initiate pairing with the display device that is separate from the ultrasound probe, and a first transceiver comprising a first processing circuitry that is configured to communicate over a communication link with the display device,
the display device having a reader that includes one or more sensors configured to sense the first light of the visual representation displayed by the ultrasound probe and a decoder configured to decode the first data from the first light, and a second transceiver comprising a second processing circuitry that is configured to initiate communication with the first processing circuitry to pair the ultrasound probe and the display device over the communication link based on the first data.

2. The ultrasound system as described in claim 1 , wherein the first light includes at least one of a quick response (QR) code, a bar code, an animation sequence, a pattern, and an image.

3. The ultrasound system as described in claim 1 , wherein the interface is sealed from an environment outside the ultrasound probe.

4. The ultrasound system as described in claim 3 , wherein the interface includes an array of light emitting diodes (LEDs) that are visibly hidden from the environment when the LEDs are inactive.

5. The ultrasound system as described in claim 1 , wherein the ultrasound probe is a first ultrasound probe that is implemented to communicate with an additional ultrasound probe over an additional communication link to indicate that the first ultrasound probe is in said communication with the display device and is not available for pairing with the additional ultrasound probe.

6. The ultrasound system as described in claim 1 , wherein the ultrasound probe includes a light source configured to project a second light onto a patient to indicate an insertion point for an interventional instrument.

7. The ultrasound system as described in claim 6 , wherein the light source is configured to project the second light onto the patient to indicate a shape of a blood vessel.

8. The ultrasound system as described in claim 6 , wherein the light source includes at least one of light emitting diodes (LEDs) of the display, a mini projector, and a MEMS device, and the light source is implemented to generate the second light with the at least one of the LEDs, the mini projector, and the MEMS device.

9. The ultrasound system as described in claim 1 , wherein the ultrasound probe includes:
a transducer system implemented to generate ultrasound data based on reflections of ultrasound signals transmitted by the transducer system at a patient-worn identifier; and
a processor implemented to determine patient identification data based on the ultrasound data;
wherein at least one of the interface and the display device is implemented to display the patient identification data.

10. The ultrasound system as described in claim 1 , wherein the ultrasound probe is configured to obtain an instruction to move the ultrasound probe, and the interface is configured to display an additional visual representation that indicates how to move the ultrasound probe based on the instruction.

11. The ultrasound system as described in claim 1 , wherein the ultrasound probe is configured to receive a removable head having a transducer array, and the interface is configured to display an identifier of the removable head.

12. The ultrasound system as described in claim 11 , wherein identifier indicates the transducer array as one of linear, planar, phased, and curved.

13. An ultrasound system comprising:
a display device; and
an ultrasound probe having at least one light source configured to emit a first light and a processor configured to encode first data into the first light to initiate pairing with the display device that is separate from the ultrasound probe, the
display device having a receiver including one or more sensors configured to sense the first light and a decoder configured to decode the first data from the first light, wherein:
the ultrasound probe includes a first transceiver comprising a first processing circuitry that is configured to communicate over a communication link;
the display device includes a second transceiver comprising a second processing circuitry that is configured to communicate over the communication link; and
the second processing circuitry is implemented to, based on the first data decoded from the first light, initiate communication with the first processing circuitry to pair the ultrasound probe and the display device over the communication link.

14. The ultrasound system as described in claim 13 , wherein the processor is implemented to encode the data into the first light by modulating at least one of a frequency of the first light, a phase of the first light, an amplitude of the first light, and a polarization of the first light.

15. The ultrasound system as described in claim 13 , wherein the at least one light source includes multiple light sources, and the processor is implemented to encode the data into the first light based on locations of the multiple light sources on the ultrasound probe.

16. The ultrasound system as described in claim 13 , wherein the light includes visible light having a wavelength between 380 nanometers and 740 nanometers.

17. The ultrasound system as described in claim 13 , wherein the at least one light source includes multiple light sources, and further comprising a registration system including:
one or more light sensors implemented to sense the first light emitted from the multiple light sources; and
a processor system implemented to determine an orientation of the ultrasound probe based on the first light sensed by the one or more light sensors.

18. The ultrasound system as described in claim 13 , wherein the data indicates at least one of an availability, a battery status, a cleanliness status, and a transducer configuration of the ultrasound probe.

19. An ultrasound probe comprising:
a display interface including an array of light emitting diodes (LEDs) configured to emit a first light pattern to sense by one or more sensors of a display device that is separate from the ultrasound probe, the first light pattern representing first data to initiate pairing with the display device over a communication link, wherein the LEDs are visibly hidden from an environment outside the ultrasound probe when the LEDs are inactive, the display interface being sealed from the environment; and
a first transceiver coupled to the display interface, the first transceiver comprising a first processing circuitry that is configured to communicate with the display device over the communication link, the display device comprising the one or more sensors configured to sense the first light pattern and a second processing circuitry coupled to the one or more sensors, wherein the first processing circuitry is configured to receive a communication from the second processing circuitry over the communication link to pair the ultrasound scanner and the display device in response to the one or more sensors sensing the first light pattern indicating the first data.
