Abstract

A diagnostic medical imaging ultrasound system comprises a flat panel display device to provide ultrasound images to an operator. The flat panel display device produces an image with sufficient contrast ratio, response time, and angular fidelity to display high-quality ultrasound images. The display device is secured to an ultrasound system cart and can be positioned away from the cart. The display device can also be secured to a structure that is physically independent from an ultrasound image generator and can be ergonomically positioned with respect to a patient and operator for superior ergonomics.

Claims

1. A diagnostic medical imaging ultrasound system comprising:

an ultrasound system cart;

an ultrasound image generator integrated with the cart, the image generator comprising a transmit beamformer, a receive beamformer, and a signal processor responsive to the receive beamformer; and

a flat panel display device supported by the cart and responsive to the signal processor, the flat panel display device being operative to display an ultrasound image generated by the ultrasound image generator.

2. The invention of claim 1, wherein the ultrasound system is characterized by a center of gravity less than about 24 inches from a floor.

3. The invention of claim 1, wherein the ultrasound system cart is characterized by a front and rear wheel centerline, and wherein the ultrasound system is characterized by a center of gravity less than about 14 inches from the front and rear wheel centerlines.

4. The invention of claim 1, wherein the ultrasound system cart is characterized by a wheelbase length, and wherein the ultrasound system cart is characterized by a wheelbase length less than about 27 inches.

5. The invention of claim 1, wherein the ultrasound system cart is characterized by a track width, and wherein the ultrasound system cart is further characterized by a track width less than about 22 inches.

6. The invention of claim 1, further comprising means for adjustably positioning the flat panel display device with respect to the cart.

11. The invention of claim 1 or 7, wherein the flat panel display device is adapted to produce an image having a contrast ratio exceeding about 300:

1.

12. The invention of claim 1 or 7, the flat panel display device is adapted to produce an image having a response time of less than about 33 milliseconds.

13. The invention of claim 1 or 7, wherein the flat panel display device comprises a face, and is adapted to produce an image characterized by an angular fidelity of the properties of the rendered light with a ±

45 degree cone originating from and comprising an axis of symmetry upright to the face of the flat panel display.

14. The invention of claim 1 or 7, wherein the flat panel display device is adapted to provide an active image area larger than about 10 inches diagonal and a total number of color pixels greater than about 400,000.

15. The invention of claim 6 or 7, wherein the means for positioning comprises means for tilting the flat panel display device over a range greater than 90 degrees.

16. The invention of claim 6 or 7, wherein the means for positioning comprises means for swiveling the flat panel display device through a range greater than 90 degrees.

17. The invention of claim 6 or 7, wherein the flat panel display device is characterized by a horizontal position, and wherein the means for positioning comprises means for extending the horizontal position through a range greater than about 6 inches.

18. The invention of claim 6 or 7, wherein the ultrasound image generator comprises a perimeter, and wherein the means for positioning comprises means for extending the flat panel display device beyond the perimeter of the ultrasound image generator.

19. The invention of claim 6 or 7, wherein the flat panel display device is characterized by a height, and wherein the means for positioning comprises means for adjusting the height of the flat panel display device.

20. The invention of claim 6 or 7, wherein the means for positioning comprises:

at least one arm having a first end and a second end, the first end attaching to the flat panel display device; and

at least one hinge attaching to the second end for horizontally and vertically extending the flat panel display device.

21. The invention of claim 6 or 7, wherein the means for positioning comprises a swiveling hinge, articulation of the swiveling hinge tilting the flat panel display device about a horizontal axis and swiveling the flat panel display device about a vertical axis.

22. The invention of claim 6 or 7, wherein the means for positioning comprises a pivoting arm for horizontally extending the flat panel display device.

23. The invention of claim 6 or 7, wherein the means for positioning comprises a ball and socket, articulation of the ball and socket providing the flat panel display device with three axes of rotation.

24. The invention of claim 6 or 7, wherein the means for positioning comprises a swiveling yoke, articulation of the yoke tilting the flat panel display device about a horizontal axis, swiveling the flat panel display device about a vertical axis, and vertically and horizontally extending the flat panel display device.

25. The invention of claim 6 or 7, wherein the means for positioning comprises a swiveling bar-linkage device for tilting the flat panel display device about a horizontal axis, swiveling the flat panel display device about a vertical axis, and horizontally extending the flat panel display device.

26. The invention of claim 6 or 7, wherein the means for positioning comprises a telescopic slide for vertically extending the flat panel display device.

27. The invention of claim 6 or 7, wherein the means for positioning comprises:

a tongue; and

a sleeve attaching to the flat panel display device and slidable along the tongue to provide the flat panel display device with vertical extension along the tongue.

28. The invention of claim 6 or 7, wherein the means for positioning comprises a bar-linkage device for tilting the flat panel display device about a horizontal axis.

29. The invention of claim 6 or 7, wherein the means for positioning comprises a circular slide for vertically extending the flat panel display device.

7. A diagnostic medical imaging ultrasound system for forming an ultrasound image of a patient, the system comprising:

an ultrasound cart,
