摘要：
Described embodiments include a system, method, and computer program product. A described system includes a receiver circuit that receives a first reference image that includes an objective landmark subsurface feature of a mammalian body part, and receives a second reference image that includes a present-location landmark subsurface feature of the mammalian body part. The objective landmark subsurface feature has a first spatial relationship to a destination region of interest of the mammalian body part. The present-location landmark subsurface feature has a second spatial relationship to a distal end portion of a body-insertable device. The system includes a feature matching circuit that determines a substantial correspondence between the present-location landmark subsurface feature and the objective landmark subsurface feature. The system includes a proximity indicator circuit that generates informational data indicative of an operational proximity of the distal end portion of the body-insertable device to the destination region of interest.
