System and method for light based lung visualization
First Claim
1. A system for light-based interrogation comprising:
- a memory storing a pre-procedural three-dimensional (3D) model of a luminal network and a pathway plan illustrating a pathway in the pre-procedural 3D model to a target identified in the pre-procedural 3D model, wherein the pre-procedural 3D model is made of a plurality of two dimensional (2D) images, which are from computed tomography scanning, magnetic resonance imaging (MRI), fluoroscopic imaging, or X-ray imaging;
an electromagnetic (EM) board configured to generate an EM field;
an extended working channel (EWC) configured to navigate a luminal network of a patient toward the target in accordance with the pathway plan;
an EM sensor located at a distal portion of a medical device, which is extending distally from a distal end of the EWC, and configured to sense the EM field;
a light source located at the distal portion of the EWC and configured to emit light;
a light receptor located at the distal portion of the EWC and configured to sense light reflected from airway of the luminal network; and
a processor configured to convert the reflected light into light based data and identify one or more physiological features, generate a visible image, and generate an intra-procedural 3D model by replacing at least one of the plurality of 2D images of the pre-procedural 3D model at a location that corresponds to a detected location of the EM sensor with the visible image, the intra-procedural 3D model generated based on a predetermined offset between the EM sensor and the light receptor.

Abstract
A system for light based interrogation of a lung includes a memory, an electromagnetic (EM) board, an extended working channel (EWC), an EM sensor, a light source, a light receptor and a processor. The memory stores a 3D model and a pathway plan of a luminal network and the EM board generates an EM field. The EWC navigates a luminal network of a patient toward a target in accordance with the pathway plan and the EM sensor extends distally from a distal end of the EWC and is configured to sense the EM field. The light source is located at or around the EWC and emits light, and the light receptor is located at or around the EWC and is configured to sense reflected light from airway of the luminal network. The processor converts the reflected light into light based data and identifies a type or density of tissue.
