Abstract

BACKGROUND:

In recent years the visualization of biomagnetic measurement data by so-called pseudo current density maps or Hosaka-Cohen (HC) transformations became popular.

METHODS:

The physical basis of these intuitive maps is clarified by means of analytically solvable problems.

RESULTS:

Examples in magnetocardiography, magnetoencephalography and magnetoneurography demonstrate the usefulness of this method.

CONCLUSION:

Hardware realizations of the HC-transformation and some similar transformations are discussed which could advantageously support cross-platform comparability of biomagnetic measurements.
