Abstract

A method and system for three dimensional scanning, imaging and/or therapy are provided. In accordance with one aspect, an exemplary method and system are configured to facilitate controlled scanning within one-degree of freedom. For example, an exemplary method and system can enable multiple two-dimensional image planes to be collected in a manner to provide an accurate and computationally efficient three-dimensional image reconstruction while providing the user with a user-friendly mechanism for acquiring three-dimensional images. In accordance with an exemplary embodiment, an exemplary scanning and imaging system comprises an imaging probe, a control system, a positioning system and a display system. In accordance with an exemplary embodiment, the positioning system comprises a guide assembly and a position sensing system. The guide assembly is configured to provide pure rectilinear or rotational motion of the probe during scanning operation while the position sensing system is configured to detect the direction and position of the probe during scanning.

Claims

1. A method for facilitating controlled scanning of an imaging probe relative to a region of interest, said method comprising:

holding an imaging probe in a hand;

scanning a region of interest with said imaging probe in said hand;

restricting movement of said imaging probe through use of a guide assembly to rotation around an axis which is substantially perpendicular to a surface of the region of interest; and

determining position of said imaging probe within said guide assembly through use of a position sensing system to facilitate three-dimensional reconstruction of images by a control system, wherein restricting movement comprises coupling a guide member to said imaging probe.

2. The method according to claim 1, wherein restricting movement comprises controlling movement in a rotational manner.

3. The method according to claim 1, further comprising collecting a plurality of two-dimensional image planes to facilitate said three-dimensional reconstruction of images by a control system.

4. The method according to claim 1, wherein said imaging probe comprises an ultrasound transducer configured with at least one of a single element, multiple element, or electronic array based transducer.

5. The method according to claim 1, wherein said imaging probe is a combined imaging/therapy probe.

6. The method according to claim 5, further comprising placing at least one therapeutic lesion with said combined imaging/therapy probe in said region of interest along said movement of said combined imaging/therapy probe through the use of the guide assembly.

7. The method according to claim 1, further comprising monitoring at least one tissue parameter and reporting to said control system.

8. The method according to claim 1, further comprising providing therapeutic treatment to said region of interest.

9. A method for facilitating controlled scanning of an imaging probe relative to a region of interest, said method comprising:

holding an imaging probe in a hand;

scanning a region of interest with said imaging probe in said hand;

restricting movement of said imaging probe within one-degree, of freedom through use of a guide assembly to rectilinear along a plane which is substantially parallel to a surface of the region of interest; and

determining position of said imaging probe within said guide assembly through use of a position sensing system to facilitate three-dimensional reconstruction of images by a control system.

10. The method according to claim 9, further comprising collecting a plurality of two-dimensional image planes to facilitate said three-dimensional reconstruction of images by a control system.

11. The method according to claim 9, further comprising coupling the guide member to said imaging probe.

13. The method according to claim 9, wherein said imaging probe is a combined imaging/therapy probe.

14. The method according to claim 13, further comprising placing at least one therapeutic lesion with said combined imaging/therapy probe in said region of interest along said movement of said probe through the use of the guide assembly.

15. The method according to claim 9, further comprising monitoring at least one tissue parameter and reporting to said control system.

16. The method according to claim 9, further comprising providing therapeutic treatment to said region of interest.

17. A method for facilitating controlled scanning of an imaging probe relative to a region of interest, said method comprising:

holding an imaging probe in a hand;

scanning a region of interest with said imaging probe in said hand;

restricting movement of said imaging probe within one-degree of freedom through use of a guide assembly to a prescribed path which is substantially parallel to a surface of the region of interest; and

determining position of said imaging probe within said guide assembly through use of a position sensing system to facilitate three-dimensional reconstruction of images by a control system.

18. The method according to claim 17, further comprising collecting a plurality of two-dimensional image planes to facilitate said three-dimensional reconstruction of images by a control system.

19. The method according to claim 17, further comprising coupling the guide member to said imaging probe.

20. The method according to claim 17, wherein said imaging probe comprises an ultrasound transducer configured with at least one of a single element, multiple element, or electronic array based transducer.

21. The method according to claim 17, wherein said imaging probe is a combined imaging/therapy probe.

22. The method according to claim 21, further comprising placing at least one therapeutic lesion with said combined imaging/therapy probe in said region of interest along said movement of said probe through the use of the guide assembly.
