Augmented reality viewing and tagging for medical procedures
Technology is described for augmenting medical imaging for use in a medical procedure. The method can include the operation of receiving an image of patient anatomy captured by a visual image camera during the medical procedure. An acquired medical image associated with the patient anatomy can then be retrieved. Another operation can be associating the acquired medical image to the patient anatomy. An augmentation tag associated with a location in one layer of the acquired medical image can be retrieved. A further operation can be projecting the acquired medical image and the augmentation tag using an augmented reality headset to form a single graphical view as an overlay to the patient anatomy in either 2D, 3D or holographic form.

10. The non-transitory machine readable storage medium as in claim 8 , further comprising using a visually scannable symbol attached to a patient to retrieve an identity of a patient and to enable retrieval of the acquired 3D medical image associated with the visually scannable symbol.
11. The non-transitory machine readable storage medium as in claim 8 , further comprising using the image inversion prevention tag to ensure the acquired 3D medical image is not inverted with respect to the patient anatomy.
12. The non-transitory machine readable storage medium as in claim 8 , further comprising:
combining an endoscopic video feed with the acquired 3D medical image and the augmentation tag which is overlaid on the patient anatomy viewable by a medical professional through lenses of the augmented reality headset; and
using the augmentation tag to identify a size and shape of one or more 3D anatomical structures in the endoscopic video feed and to match where an endoscope is estimated to be located in the patient anatomy using the augmentation tag.
13. A system, comprising:
an augmented reality headset through which to view patient anatomy during a medical procedure;
a processor in the augmented reality headset configured to:
capturing morphometric measurements of the patient anatomy through the augmented reality headset;
identify a patient marker of the patient anatomy using the augmented reality headset, the patient marker comprising information identifying a patient in order to retrieve pre-measured morphometric measurements;
retrieving pre-measured morphometric measurements associated with the patient anatomy using the patient marker identified using the augmented reality headset;
determining whether the morphometric measurements of the patient anatomy match the pre-measured morphometric measurements;
retrieving an acquired 3D medical image associated with the patient anatomy as defined by the patient marker and matched morphometric measurements;
aligning the acquired 3D medical image to the patient using the augmented reality headset and the morphometric measurements; and
displaying the acquired 3D medical image and an augmentation tag identifying at least one anatomical structure within the acquired 3D medical image on a view of the patient anatomy using the augmented reality headset.
14. The system as in claim 13 , wherein the morphometric measurements are shape, width, height, depth and contour of an appendage or patient anatomy.
15. The system as in claim 13 , wherein the acquired 3D medical image is displayed using the augmented reality headset with the acquired 3D medical image projected on a semi-transparent optical imaging area.
16. The system as in claim 13 , further comprising matching a patient orientation marker with an image orientation tag in the acquired 3D medical image to enable correct orientation of the acquired 3D medical image with the patient anatomy.
17. The system as in claim 13 , wherein the patient marker is a scannable symbol including at least one of: a 1D (one dimensional) bar code, a 2D (two dimensional) bar code, a picture, a custom generated geometric shape, or a RFID (radio frequency ID) used to retrieve an identity of the patient and to retrieve the acquired 3D medical image.
