(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

Abstract
Described embodiments include a system, method, and computer program product. A described system includes a receiver circuit that receives a first medical image. The first medical image includes a selected target region of interest of an individual patient'"'"'s body part, and a landmark subsurface feature of the individual patient'"'"'s body part having a first spatial relationship with the selected target region. The receiver circuit receives a second medical image that includes a candidate region of interest of the individual patient'"'"'s body part, and a landmark feature of the individual'"'"'s patient body part having a second spatial relationship with the candidate region. A feature matching circuit determines a correspondence between the candidate landmark subsurface feature and the associated landmark subsurface feature. A reporting circuit generates informational data indicating the second medical image includes at least a portion of the selected target region of interest. A communication circuit outputs the informational data.
