- // Executes a series of trials to test the effects of lung polyhedra with
- // varying conductivities. The first trial employs no lung polyhedra. The
- // second trial employs lung polyhedra with the same conductivity as the base
- // torso, and should produce results identical to the first trial.
- // Each successive trial employs a linearly decreased lung conductivity.
- //
- // Upon execution, the "channeling" effect described by Gulrajani and
- // Mailloux (see the document "CESLab Technical Specifications" for more
- // information) should be evident in anterior VCG viewers as an increase
- // in Y-axis oriented (vertical
- // in torso space) current dipoles in the later trials, and a corresponding
- // diminuition of
- // dipole along the other axes. This effect should become stronger as
- // lung conductivity decreases.
- //
- // In a superior VCG view, the lung channeling effect should be manifested
- // as decreases in left-right dipole, and corresponding increase in dipole
- // along the Z-axis.
