Abstract

In an embodiment, there is an apparatus for facilitating ultrasound medical image acquisition. There is a guide to help guide an ultrasound probe during a scanning operation. The guide resists at least some undesired movement of the ultrasound probe. The at least some undesired movement is otherwise possible, without the guide, under freehand probing. In another embodiment, there is a method for facilitating ultrasound image acquisition. The method includes providing a guide; guiding an ultrasound probe during a scanning operation using the guide, including resisting at least some undesired movement of the ultrasound probe; wherein the at least some undesired movement is otherwise possible, without the guide, under freehand probing. The guide and guiding are especially beneficial for three-dimensional or panoramic ultrasound imaging.

Claims

1. An apparatus for facilitating ultrasound medical image acquisition, the apparatus comprising:

at least one member configured to help guide an ultrasound probe during a scanning operation, to resist at least some undesired movement of the ultrasound probe;

wherein the at least some undesired movement is otherwise possible, without the member, under freehand probing.

2. An apparatus according to claim 1, wherein the at least one member comprises a flat or curved rail defining a trajectory along a surface of skin, the rail being configured to resist movement of the ultrasound probe at least in a direction along the surface that is other than the defined trajectory.

3. An apparatus according to claim 2, wherein the rail is configured to be directly engaged by an ultrasound-probe housing, the ultrasound-probe housing being capable of sliding along the rail.

4. An apparatus according to claim 2, further comprising a slider configured to slideably engage the rail, the slider being configured to couple to an ultrasound probe unit.

5. An apparatus according to claim 2, wherein the apparatus includes a resistive element that resists, but does not prevent, some motion even along the defined trajectory, the resistive element thereby improving ergonomic ability to maintain evenness of movement.

6. An apparatus according to claim 1, further comprising a motor drive configured to move the ultrasound probe relative to skin during a scanning operation.

7. An apparatus according to claim 6, wherein the motor drive is configured to move the ultrasound probe according to predetermined target speed, the predetermined target speed being used to process imaging data from the scanning operation.

8. An apparatus according to claim 1, wherein the apparatus lacks a motor drive for driving the ultrasound probe, and wherein the apparatus is suitable for the ultrasound probe to be manually moved, with movement guidance being contributed by the apparatus.

9. An apparatus according to claim 1, further comprising at least one sensor, the at least one sensor being configured to detect at least a first and a second position of the ultrasound probe during a scanning operation, and to communicate detection of the first and second position of the ultrasound probe to an ultrasound information processing system.

10. The apparatus according to claim 9, wherein the first and second positions are indicative of, respectively, a start and a finish of a desired scanning operation.

11. The apparatus according to claim 9, further comprising a communication adaptor configured to communicate the detection of the first and second position of the ultrasound probe to the ultrasound information processing system via a foot-switch input of the conventional ultrasound information processing system.

12. The apparatus according to claim 1, wherein the member is configured to help guide the ultrasound probe, with the ultrasound probe oriented for at least one of a three-dimensional scanning operation or a panoramic scanning operation.

13. An apparatus according to claim 1, further comprising:

a medical ultrasound imaging system that includes a computer system, ultrasound image acquisition and processing software; and

the ultrasound probe.

14. A method for facilitating ultrasound image acquisition, comprising:

providing a guide;

guiding an ultrasound probe during a scanning operation using the guide, including resisting at least some undesired movement of the ultrasound probe;

wherein the at least some undesired movement is otherwise possible, without the guide, under freehand probing.

15. A method according to claim 14, wherein the guide comprises a flat or curved rail defining a trajectory along a surface of skin, and the at least some undesired movement includes movement of the ultrasound probe at least in a direction along the surface that is other than the defined trajectory.

16. A method according to claim 15, wherein the guide further comprising a slider configured to slideably engage the rail, the method further comprising accepting the ultrasound probe to be coupled to the slider.

17. A method according to claim 14, further comprising resisting, but not preventing, some motion even along the defined trajectory, thereby improving ergonomic ability to maintain evenness of movement.

18. A method according to claim 14, further comprising automatically driving the ultrasound probe relative to skin during a scanning operation.

19. A method according to claim 15, further comprising automatically indicating, for a medical ultrasound imaging system, a starting and a finishing of a desired scanning operation.

20. A method of ultrasound image acquisition according to claim 14, further comprising conducting an ultrasound scanning operation, including activating the ultrasound probe, moving the ultrasound probe, receiving signals from the ultrasound probe at a medical ultrasound imaging system to obtain a three dimensional or a panoramic ultrasound image.
