Abstract: Systems, devices, methods, and computer program products for identifying and mitigating image-to-body divergence are disclosed herein. In some embodiments, a method includes receiving sensor data from a medical device while the medical device is inserted within an anatomic region of a patient and after it has been registered to an anatomic model of the anatomic region, where the anatomic model is based on previously-obtained image data of the anatomic region and includes a virtual path extending throughout the anatomic model to an anatomic structure of interest, and where sensor data indicates a location of at least a portion of the medical device; comparing the sensor data to a corresponding portion of the virtual path; based at least in part on the comparison, producing a divergence classifier indicative of a divergence of the anatomic region from the anatomic model; and generating an alert when the divergence classifier exceeds a predetermined threshold.

Abstract: Disclosed is a process for removing contaminants from a contaminated area of the ground having a vadose zone and a water table which comprises providing a borehole in the contaminated area; placing in the borehole a perforated riser pipe inside of which is situated a vacuum extraction pipe with an opening situated near, at, or at any point below the water table within the perforated riser pipe; while introducing a gas into the riser pipe, applying a vacuum to the vacuum extraction pipe to draw gases and liquid from the soil into the perforated riser pipe and from the riser pipe into the vacuum extraction pipe and transport both the gases and the liquid to the surface as a common stream; forming from the common stream a stream which is primarily liquid and a stream which is primarily gaseous; and separately treating the separated liquid and gas streams. Also disclosed is an apparatus for carrying out the process.
