Abstract

The present invention relates to a lightweight, high resolution portable ultrasound system using components and methods to improve connectivity and ease of use. A preferred embodiment includes an integrated system in which the beamformer control circuitry can be inserted into the host computer as a peripheral or within the processor housing.

Claims

1. An ultrasound imaging system including a mobile cart for a portable ultrasound display and processing device, the ultrasound imaging system comprising:

a handheld display and image processor housing having a first electrical connector;

a computer within the handheld display and image processor housing;

a touch screen graphical user interface operable on the display and image processor housing, the display being mounted within the handheld display and image processor housing over the computer such that a user can view and operate the display;

a virtual control panel to actuate an ultrasound imaging operation using the display within the handheld display and image processor housing;

a beamformer within the handheld display and image processor housing, the beamformer being connected to receive image signals from a transducer connector during an imaging procedure;

a memory and a battery within the handheld display and image processor housing;

a base assembly having a second electrical connector configured to electrically connect to the handheld display and image processor housing that can be detachably mounted onto the base assembly such that the handheld display and image processor housing is powered by the battery, the second electrical connector including an external network connection and wherein the base assembly supports a control panel that separately operates the handheld display and image processor housing;

a plurality of tranducer connection ports such that a plurality of transducers electrically connect to the ultrasound imaging system, wherein each transducer connection port comprises a transmit and receive integrated circuit; and

a cart on which the base assembly is mounted, the cart carrying a direct current (DC) source electrically connectable to the handheld display and image processor housing and further including a wheel assembly.

2. The system of claim 1, further comprising a cable-less interface configured to mate the handheld image processor housing to the cart assembly.

3. The system of claim 1, further comprising a plurality of control elements coupled to the cart configured to activate the display of image data on the display being mounted within the handheld display and image processor housing.

4. The system of claim 1, further comprising an operator console coupled to the cart assembly.

5. The system of claim 1, further comprising a control panel configured to receive a user command to control a plurality of control panel elements.

6. The system of claim 1, wherein the cart assembly further comprises a plurality of control elements to actuate the display.

7. The system of claim 1, wherein the display resolution further comprises:

a minimum display resolution of 1024×

8. The system of claim 1, further comprising a modular computer circuit board.

9. The system of claim 1, wherein the transducer connector further comprises:

a modular transducer connector.

10. The system of claim 1, further comprising a transducer array within a transducer probe that is connected to the transducer connector with a cable.

11. The system of claim 1, wherein the computer further comprises a processor configured to identify transducer data.

12. The system of claim 1, wherein the computer further comprises a processor configured to display data on the display.

13. The system of claim 1 further comprising a processor configured to receive data from a plurality of transducers during a ultrasound procedure.

14. The system of claim 1, wherein the control panel further comprises a keypad coupled to the base assembly to actuate an ultrasound imaging operation using the handheld display and image processor housing.

15. The system of claim 1, further comprising a switch to select between the plurality of transducer connectors.

16. The system of claim 1, further comprising a transducer connector having at least a 160 pin socket.

17. The system of claim 1, further comprising a transducer connector having a latching mechanism.

18. The system of claim 1, further comprising a transducer connection circuit having a one wire identification chip.

19. The system of claim 1, further comprising a transducer connector having a single wire connection.

20. The system of claim 1, further comprising a transducer connector configured for bidirectional transfer of data in series between the transducer connector and the handheld display and image processor housing.

21. The system of claim 1, further comprising a battery module for powering an electronic circuit.
