1. A method of treating a target in a lung of a patient, comprising:

  • positioning a leadless marker in the lung of the patient relative to the target;

    collecting position data of the implanted marker with a localization system using a non-ionizing energy to track the implanted marker while the patient is in a treatment session;

    determining the location of the implanted marker in an external reference frame based on the collected position data;

    providing an objective output in the external reference frame that is (a) directly responsive to movement of the implanted marker and (b) provided at a periodicity that tracks the location of the target;

    wherein the position data is collected at a time tn, and wherein providing the objective output responsive to the location of the target comprises providing the objective output to at least one of a user interface, a memory device, a computer and a medical device within a latency period, wherein the position data is collected by the localization system; and

    wherein the latency period between the movement of the implanted marker and the objective output of the collected position data during application of therapeutic ionizing radiation is not greater than approximately 2 seconds of time tn and the objective output is provided at a periodicity not greater than approximately 2 seconds during the application of the therapeutic ionizing radiation.
