Optical needle guide for ultrasound guided needle biopsy
First Claim
Patent Images
1. An optical guide for a biopsy needle comprising:
- a light projector for producing a line of light on a patient'"'"'s skin surface;
said light projector mounted on an ultrasound transducer exhibiting an ultrasound imaging plane; and
said light projector being aligned such that said line of light corresponds with an intersection of said ultrasound imaging plane with said skin surface so as to indicate a line of potential entry points for said biopsy needle located in said ultrasound imaging plane.

18. A method for optically guiding a biopsy needle comprising the steps of:
-
affixing a light projector for producing a line of light on a patient'"'"'s skin onto an ultrasound imaging device, such that said line of light coincides with an imaging plane of said ultrasound device;
ultrasound imaging said patient for a desired biopsy target; and
selecting a point from one of a plurality of potential entry points along the line of light for inserting said biopsy needle in a path toward said target. - View Dependent Claims (19)
aligning the biopsy needle with the line of light such that the biopsy needle is illuminated along its length by the light projector.
