Classification: CPC A  G | IPC A  G

Claim 0:
1. A non-transitory computer-readable storage medium storing instructions which, when executed by a computer, cause the computer to:
cause presentation of a 3D model of a luminal network;
cause generation of, by an electromagnetic (EM) field generator of a tracking system, an EM field about a patient's chest;
receive a detection a location of an EM sensor of the tracking system within the EM field;
determine a position of a tool within the patient's chest based on the location of the EM sensor detected;
cause display of an indication of the position of the tool on the 3D model;
provide guidance for positioning a cone beam computed tomography (CBCT) imaging device based on the location of the EM sensor detected;
actively track a location of the CBCT imaging device via a sensor included in the CBCT imaging device;
determine whether the CBCT imaging device is moved into the EM field based at least in part on data received by the tracking system from the sensor included in the CBCT imaging device;
compensate for distortion of the EM field caused by the CBCT imaging device being disposed within the EM field by adjusting the indication of the position of the tool displayed on the 3D model in response to determining that the CBCT imaging device is moved into the EM field;
cause the EM field generator to be disabled after providing guidance for positioning the CBCT imaging device based on the location of the EM sensor detected in response to determining that the CBCT imaging device is not moved into the EM field;
receive CBCT image data of the patient's chest from the CBCT imaging device while the EM field generator is disabled; and
cause the EM field generator to be enabled after receiving the CBCT image data of the patient's chest while the EM field generator is disabled.
