Identification and notification of tool displacement during medical procedure

A method comprising:

• detecting a position of a sensor within a luminal network of a patient as the sensor moves towards a target location;
• determining that the sensor is at a position within a first threshold distance from the target;
• monitoring the position of the sensor;
• determining that the sensor has moved from the determined position within the threshold distance from the target;
• determining whether movement from the determined position within the threshold distance from the target exceeds a second threshold distance;
• and
• providing guidance for on a user interface when the determined movement exceeds the second threshold distance.

A system for alerting a user of movement of a tool, the system comprising:

• a tool navigable through a luminal network, the tool including a sensor;
• a computing device including a processor and memory configured to receive outputs from the sensor and storing in the memory an application which when executed by the processor, causes the computing device to:
• detect a position of the tool within the luminal network as the sensor moves towards a pre-determined target location;
• determine that the tool is at a position within a first threshold distance from the pre-determined target;
• monitor the position of the tool;
• determine that the tool has moved from the determined position within the threshold distance from the target;
• and
• providing guidance on a user interface for repositioning of the tool when the movement from the determined position within the threshold distance from the target exceeds a second threshold distance.
