1. A system for confirming a match between a candidate region of interest of a body part of an individual patient and previously selected target region of interest of the body part of the individual patient, the system comprising:

  • (a) a receiver circuit configured to receive(i) a first medical image that includes the selected target region of interest and that includes a first landmark subsurface feature of a cavity or lumen of the body part, the first landmark subsurface feature of the cavity or lumen including a subsurface vessel, blood vessel, vascular structure, or a pattern presented by one or more blood vessel of the cavity or lumen of the body part, the first landmark subsurface feature of the cavity or lumen having a first spatial relationship with the selected target region of interest; and

    (ii) a second medical image that includes a candidate region of interest and that includes a second landmark feature of the cavity or lumen of the body part, the second landmark subsurface feature of the cavity or lumen including a subsurface vessel, blood vessel, vascular structure, or a pattern presented by one or more blood vessel of the cavity or lumen of the body part, the second landmark feature of the cavity or lumen having a second spatial relationship with the candidate region of interest;

    (b) a feature matching circuit configured to determine a substantial correspondence between the second landmark subsurface feature of the cavity or lumen and the first landmark subsurface feature of the cavity or lumen;

    (c) a reporting circuit configured to generate informational data indicating that the candidate region of interest in the second medical image includes at least a portion of the selected target region of interest, the informational data at least partially based on the determined substantial correspondence between the second landmark subsurface feature of the cavity or lumen and the first landmark subsurface feature of the cavity or lumen;

    (d) a comparative-analysis circuit configured to detect change in the target region of interest included in the candidate region of interest in the second image from the target region in the first image; and

    (e) a communication circuit configured to output the informational data.
