Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 18:
19. A non-transitory computer-readable storage medium storing instructions which, when executed by a computer, cause the computer to:
determine a position of a tool within a patient's chest based on a location of an electromagnetic (EM) sensor within an EM field generated by an EM field generator of a tracking system;
cause display of an indication of the position of the tool on a 3D model;
actively track a location of an imaging device via a sensor included in the imaging device;
determine whether the 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 imaging device;
compensate for distortion of the EM field caused by the 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 imaging device is moved into the EM field;
cause the EM field generator to be disabled after providing guidance for positioning the imaging device based on the location of the EM sensor detected in response to determining that the imaging device is not moved into the EM field;
receive image data of the patient's chest from the imaging device while the EM field generator is disabled; and
cause the EM field generator to be enabled after receiving the image data of the patient's chest while the EM field generator is disabled.
