Multichannel radiography employing scattered radiation

摘要

A diagnostic imaging system and process permits construction of an image of an area of an interfacial surface within the body of a subject, such as the heart-lung interface. The imaging system includes radiation source means for generating a shaped beam of penetrating radiation for illuminating the interfacial surface. Radiation scattered from tissue at the interface is detected by a plurality of directional radiation detectors which can be automatically positioned and oriented so that their fields of view intersect the beam of radiation and the interfacial surface.
