1. A system for monitoring an approach to a target, the system comprising:
a luminal device including a distal end and configured to be inserted into a patient, the distal end of the luminal device configured to be guided proximate the target and including a sensor;
a surgical instrument configured to be guided through the luminal device, the surgical instrument including one or more indicators having a detectable property located along at least a portion of the surgical instrument; and
a computing device operably coupled to the sensor and including a processor and a memory storing instructions which, when executed by the processor, cause the computing device to:
