System and method for lung visualization using ultrasound
First Claim
1. A method for ultrasound (US) interrogation comprising:
- importing a three dimensional (3D) model of a luminal network and a pathway plan illustrating a pathway toward a target in the luminal network of the 3D model into a navigation system, wherein the 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;
generating an electromagnetic (EM) field about a luminal network;
inserting, by following the pathway plan, a first catheter, through which a second catheter is extended, to navigate the luminal network, wherein an EM sensor is positioned at a distal portion of one of the first catheter and the second catheter, and a US transducer is positioned at a distal portion of the other one of the first catheter and the second catheter;
sensing, at the EM sensor, the EM field;
synchronizing a location of the EM sensor in the EM field with the 3D model;
transmitting, at the US transducer, US waves;
receiving, at the US transducer, reflected US waves;
processing the reflected US waves to generate US images;
integrating the generated US images with the 3D model by replacing at least one of the plurality 2D images of the 3D model at a location of the US transducer, which corresponds to a location of the EM sensor, with the generated US images to create an intra-procedural 3D model; and
predicting based on the US images a type, density, disease state, or sufficiency of treatment of tissue reflecting the US waves.

Abstract
A system for ultrasound interrogation of a lung including a memory, an electromagnetic (EM) board, an extended working channel (EWC), an EM sensor, a US transducer, and a processor. The memory stores a three dimensional (3D) model and pathway plan for navigating a luminal network. The EM board generates an EM field. The EWC is configured to navigate the luminal network toward a target following the pathway plan. The EM sensor extends distally from a distal end of the EWC and is configured to sense the EM field. The US transducer extends distally from a distal end of the EWC, generates US waves, and receives US waves reflected from the luminal network. The processor processes the sensed EM field to synchronize a location of the EM sensor in the 3D model, to process the reflected US waves to generate images, or to integrate the generated images with the 3D model.
