Abstract
Devices and methods for performing an interventional vascular procedure with visual guidance using one or more optical head mounted displays are disclosed. Devices and methods for compensating the display of an optical head mounted display for cardiac and/or respiratory motion are disclosed.
Claims29
A system for guiding a vascular procedure in a patient comprising:
- a stereoscopic optical head mounted display;
- one or more processors;
- and
- a vascular device,
- wherein the one or more processors are configured to receive two-dimensional (2D) intra-procedural angiographic image data from a first imaging study,
- wherein the 2D intra-procedural angiographic image data are registered in a coordinate system,
- wherein the one or more processors are configured to receive three-dimensional (3D) pre-procedural vascular image data from a second imaging study,
- wherein the one or more processors are configured to align at least one anatomic structure in the 3D pre-procedural vascular image data with a corresponding anatomic structure in the 2D intra-procedural angiographic image data in the coordinate system,
- wherein the at least one anatomic structure comprises a vascular structure, vascular landmark, vascular wall, vascular edge, vascular perimeter, vascular outline, vascular surface, vascular shape, vascular volume, vascular branch, vascular tree, take off of a vascular branch, or combination thereof,
- wherein the one or more processors are configured to track the vascular device comprising an electromagnetic sensor in real time in the coordinate system,
- wherein the one or more processors are configured to generate a 3D surface representation of at least a portion of the tracked vascular device, and wherein the one or more processors are configured to generate a 3D surface representation of at least a portion of the anatomic structure from the 3D pre-procedural vascular image data,
- wherein the one or more processors are configured to generate a 3D stereoscopic view comprising the 3D surface representation of the at least portion of the tracked vascular device, the 3D surface representation of the at least a portion of the anatomic structure and the 2D intra-procedural angiographic image data,
- wherein the stereoscopic optical head mounted display is configured to display the 3D stereoscopic view,
- wherein the one or more processors are configured to update the 3D stereoscopic view in real time for movement of the tracked vascular device.
