Method and apparatus for measuring lung density by Compton backscattering

Patent · Fri Mar 11 00:00:00 EST 1988

OSTI ID:6148665

Loo, B. W.; Goulding, F. S.

The density of the lung of a patient suffering from pulmonary edema is monitored by irradiating the lung by a single collimated beam of monochromatic photons and measuring the energies of photons compton back-scattered from the lung by a single high-resolution, high-purity germanium detector. A compact system geometry and a unique data extraction scheme are utilized to minimize systematic errors due to the presence of the chestwall and multiple scattering. 11 figs., 1 tab.
