Abstract

A positioning apparatus for adjusting the position of medical imaging instruments, such as ultrasound probes, is disclosed. The preferred implementation of the apparatus includes controls for translational movement along three axes; and controls for rotational movement around three axes. In certain implementations, the rotational movement is around a point coincident with the area of image capture.

Claims

1. An apparatus for adjusting the position of an imaging instrument, the apparatus comprising:

a) a manually controlled mechanism for providing translational movement along three axes; and

b) a manually controlled mechanism for providing rotational movement around three axes;

wherein the apparatus is configured for rotational movement around at least one axis that is proximate with the area of the instrument'"'"'s image field.

2. The apparatus according to claim 1, wherein the mechanism for providing translational movement is positioned above the mechanism for providing rotational movement.

3. The apparatus according to claim 1, wherein the mechanism for providing translational movement is positioned below the mechanism for providing rotational movement.

4. The apparatus according to claim 1, wherein the rotational movement around at least two axes is proximate with the area of the instrument'"'"'s image field.

5. The apparatus according to claim 1, wherein the mechanism for providing translational movement along three axes includes movement of a portion of the mechanism along a threaded rod.

6. The apparatus according to claim 1, wherein the mechanism for providing rotational movement around three axis includes a gear and a rack.

7. An apparatus for adjusting the position of a imaging instrument, the apparatus providing:

a) manually controlled translational adjustments along three axis; and

b) manually controlled rotational adjustments around three axis;

wherein the apparatus is configured such that when an imaging instrument is positioned on the apparatus, at least one axis of the axes of rotational adjustment is through the imaging field of the imaging instrument.

8. The apparatus according to claim 7, wherein the each of the translational adjustments and rotational adjustments may be made independent of one another.

9. An apparatus for adjusting the position of an imaging instrument, the apparatus comprising:

a manually controlled imaging instrument having an approximate imaging origin and an approximate instrument center;

wherein the apparatus permits the rotational movement of the imaging instrument around at least one axis proximate the imaging origin.

10. The apparatus according to claim 9, wherein the apparatus permits the rotational movement of the imaging instrument around at least two axes located proximate the imaging origin.

11. The apparatus according to claim 10 wherein the apparatus permits the rotational movement of the imaging instrument around three axes located proximate the imaging origin.

12. The apparatus according to claim 10, wherein the rotational movement around at least two axes is proximate with the area of the instrument'"'"'s image field.

13. The apparatus according to claim 10, wherein mechanism for providing translational movement along three axes includes movement of a portion of the mechanism along a threaded rod.

14. An apparatus for adjusting the position of an imaging instrument, the apparatus comprising:

an arrangement for retaining an imaging instrument such that the imaging instrument has an imaging origin and an apparatus origin;

wherein the apparatus permits the manually controlled rotational adjustment of the imaging instrument around at least two axis that are positioned intermediate the imaging origin and the apparatus origin.

15. The apparatus according to claim 14, wherein the each of the rotational adjustments may be made independent of one another.

16. The apparatus according to claim 14, wherein the apparatus permits the rotational adjustment of the imaging instrument around at least two axis that are positioned intermediate the imaging origin and the apparatus origin proximate the imaging origin.

17. The apparatus according to claim 14, wherein the arrangement for retaining an imaging instrument includes an integrally retained imaging instrument.

18. The apparatus according to claim 14, wherein the apparatus further permits translational adjustment of the imaging instrument along at least two axes.
