A system for providing proximity awareness to an anatomical feature, the system comprising: an electromagnetic navigation system including: an electromagnetic field generator, a treatment tool configured to be inserted into a patient's chest, wherein the treatment tool is a microwave ablation tool, and an electromagnetic sensor disposed on the treatment tool; and a computing device including a processor and a memory storing instructions which, when executed by the processor, cause the computing device to: receive image data of the patient's chest; generate a three-dimensional model of the patient's chest based on the received image data; determine a location of the anatomical feature based on the received image data and the generated 3D model; track a position of the electromagnetic sensor; iteratively determine a position of the treatment tool inside the patient's chest based on the tracked position of the electromagnetic sensor; provide instructions to indicate a proximity of the treatment tool relative to the anatomical feature, based on the determined position of the treatment tool inside the patient's chest; wherein the instructions further cause the computing device to: receive ablation settings for microwave ablation; determine a projected ablation zone based on the ablation settings and a target location; determine whether the projected ablation zone encroaches on the location of the anatomical feature; and provide an alert when a determination is made that the projected ablation zone encroaches on the location of the anatomical feature. an electromagnetic navigation system including: an electromagnetic field generator, a treatment tool configured to be inserted into a patient's chest, wherein the treatment tool is a microwave ablation tool, and an electromagnetic sensor disposed on the treatment tool; and an electromagnetic field generator, a treatment tool configured to be inserted into a patient's chest, wherein the treatment tool is a microwave ablation tool, and an electromagnetic sensor disposed on the treatment tool; and a computing device including a processor and a memory storing instructions which, when executed by the processor, cause the computing device to: receive image data of the patient's chest; generate a three-dimensional model of the patient's chest based on the received image data; determine a location of the anatomical feature based on the received image data and the generated 3D model; track a position of the electromagnetic sensor; iteratively determine a position of the treatment tool inside the patient's chest based on the tracked position of the electromagnetic sensor; provide instructions to indicate a proximity of the treatment tool relative to the anatomical feature, based on the determined position of the treatment tool inside the patient's chest; receive image data of the patient's chest; generate a three-dimensional model of the patient's chest based on the received image data; determine a location of the anatomical feature based on the received image data and the generated 3D model; track a position of the electromagnetic sensor; iteratively determine a position of the treatment tool inside the patient's chest based on the tracked position of the electromagnetic sensor; provide instructions to indicate a proximity of the treatment tool relative to the anatomical feature, based on the determined position of the treatment tool inside the patient's chest; wherein the instructions further cause the computing device to: receive ablation settings for microwave ablation; determine a projected ablation zone based on the ablation settings and a target location; determine whether the projected ablation zone encroaches on the location of the anatomical feature; and provide an alert when a determination is made that the projected ablation zone encroaches on the location of the anatomical feature. receive ablation settings for microwave ablation; determine a projected ablation zone based on the ablation settings and a target location; determine whether the projected ablation zone encroaches on the location of the anatomical feature; and provide an alert when a determination is made that the projected ablation zone encroaches on the location of the anatomical feature.
