Holographic augmented reality ultrasound needle guide for insertion for percutaneous surgical procedures
A holographic augmented reality ultrasound needle guide system and method includes an augmented reality display such as a headset wearable by a user. The augmented reality display is configured to depict a virtual ultrasound image. The augmented reality display is further configured to allow a user to select a desired reference point on the virtual ultrasound image. The system is configured to depict a holographic needle guide based on the selection of the desired reference point. The system is also configured to adjust a trajectory of the holographic needle guide to avoid intersecting undesired anatomical structures. The augmented reality display is further configured to stamp the holographic needle guide into a selectively locked trajectory and position.

8. The system of claim 1 , further comprising tracking means configured to provide enhanced visualization of at least one of an anatomy of the patient and the needle, the tracking means selected from a group consisting of an infrared marker, an electro-magnetic tracker, an optical tracker, and combinations thereof.
9. The system of claim 1 , wherein the augmented reality display is configured to depict a holographic error bar adjacent the holographic needle guide, the holographic error bar configured to alert the user of a deviation from a predetermined threshold of variance of a position of the needle in relation to a trajectory of the holographic needle guide.
10. The system of claim 1 , wherein an adjustment to the holographic needle guide depicts a physical length and a diameter of the needle.
11. The system of claim 1 , wherein the physical needle insertion guide includes a bar having a plurality of holes arranged in a linear row to depict possible insertion points.
12. The system of claim 1 , wherein the holographic needle guide is adjustable by one of the user or the remote user directly moving the holographic needle guide to a desired position.
13. The system of claim 12 , wherein after stamping the computer will not recognize movements of the user as instructions to adjust the position of the holographic needle guide.
14. A method for performing a surgical procedure, which includes percutaneous insertion of a needle by a user into a patient, the method comprising the steps of:
providing a system for guiding percutaneous insertion of a needle by a user into a patient including:
an augmented reality display configured to depict a virtual ultrasound image of a portion of the patient and configured to depict a holographic needle guide on the patient based upon selection of a reference point in the virtual ultrasound image,
