Abstract

A palmar surface may allow for ease of gripping an ultrasound transducer probe. By facing the palmar surface so that the users hand is directed downwards, towards the patient'"'"'s skin, during use, less wrist flexing may result. To allow for gripping, the cable extends from the transducer at a location other than the top of the transducer. Elastomer or other soft materials increase grip.

Claims

1. A method for ultrasound scanning with a transducer, the method comprising:

positioning an upper surface of the transducer in a palm of a user with the upper surface shaped to allow at least the thumb, a finger or thumb and finger of the user to extend off of the upper surface in a direction generally down towards an acoustic window of the transducer, the acoustic window of the transducer being a lower surface and the upper surface being substantially opposite the lower surface; and

moving the transducer in response, at least in part, to force applied by the palm of the user against the upper surface.

2. The method of claim 1 further comprising:

positioning an elastomer pad beneath the upper surface on a side surface in a position adjacent the thumb or finger.

3. The method of claim 1 wherein moving comprises pushing against the upper surface.

4. The method of claim 1 wherein moving comprises orienting the transducer with the palm of the user generally facing towards skin of a patient.

5. The method of claim 1 wherein moving comprises gripping the transducer around the upper surface of the transducer.

6. The method of claim 1 further comprising:

attaching a cable extending from the transducer at a location spaced away from an orthogonal to a center of the acoustic window.

7. The method of claim 1 further comprising:

positioning elastomer material at one or more locations on the upper surface.

8. The method of claim 1 wherein positioning the upper surface comprises positioning the upper surface with the upper surface being rounded generally in conformance with a palm shape.

9. A transducer housing for ultrasound imaging, the transducer housing comprising:

an acoustic window for positioning an array of transducing elements adjacent to skin of a patient;

a palmar surface substantially parallel with the acoustic window.

10. The transducer housing of claim 9 wherein the palmar surface is generally parallel with the skin for use of the transducing elements.

11. The transducer housing of claim 9 further comprising at least one finger grip between the acoustic window and the palmar surface.

12. The transducer housing of claim 9 further comprising an elastomer pad on the palmar surface, between the acoustic window and the palmar surface or both.

13. The transducer housing of claim 9 wherein the palmar surface is shaped to fit a palm of a user oriented with the palm of the user generally facing towards skin of a patient.

14. The transducer housing of claim 9 further comprising a lip along an edge of the palmar surface, the lip for gripping the transducer housing around the palmar surface.

15. The transducer housing of claim 9 further comprising:

a cable extending from the transducer housing at a location on or off of the palmar surface, the location spaced away from an orthogonal to a center of the acoustic window.

16. The transducer housing of claim 9 wherein the palmar surface is rounded generally in conformance with a palm shape.

17. A transducer housing for ultrasound imaging, the transducer housing comprising:

an acoustic window for positioning an array of transducing elements adjacent to skin of a patient;

a palmar surface having a maximum circumference in a first plane substantially parallel with the acoustic window, a cross sectional area being substantially aligned with the maximum circumference greater than any other cross sectional area in planes substantially parallel but different than the first plane.

18. The transducer housing of claim 17 wherein a surface area of the palmar surface greater than any other contiguous surface, the palmar surface and the contiguous surfaces defined by ridges.

19. A transducer housing for ultrasound imaging, the transducer housing comprising:

an acoustic window for positioning an array of transducing elements adjacent to skin of a patient, an orthogonal vector extending from a center of the acoustic window;

a palmar surface intersecting the orthogonal vector; and

a cable extending from the housing at a location spaced away from the orthogonal vector.

20. The transducer housing of claim 19 wherein the cable extends from the housing at an angle substantially perpendicular to the orthogonal vector.

21. The transducer housing of claim 19 wherein the location is on the palmar surface and the cable or a strain relief of the cable have an elongated cross-section.

22. The transducer housing of claim 19 wherein the location is between the palmar surface and the acoustic window, the palmar surface being an upper surface and the acoustic window being on an opposing lower surface.

23. The transducer housing of claim 19 further comprising:

a cable connector connecting the cable to the transducer housing, the cable connector being rotatable such that the cable may rotate relative to the transducer housing.
