The ELITE system.
This report describes the technical limitations that affect the computation of thoraco-abdominal volume displacement and the characteristics that an ideal system should have. The elaboratore di immagini televisive (ELITE) system satisfies many of these characteristics. ELITE system is an optoelectronic device able to track the three-dimensional co-ordinates of a number of reflecting markers placed noninvasively on the skin of the subject. The simultaneous acquisition of kinematic signals with pleural and gastric pressures during a relaxation manoeuvre allows the representation of pressure-volume plots describing the mechanical characteristics of each compartment. The results of studies concerning chest-wall mechanics by applying the ELITE system are described.
