e/Hosaka-Cohen Transformation

Information
has gloss	eng: Hosaka-Cohen Transformation (also called H-C transformation) is a mathematical method of converting a particular two-dimensional scalar magnetic field map to a particular two-dimensional vector map. The scalar field map is of the component of magnetic field which is normal to a two-dimensional surface of a volume conductor; this volume conductor contains the currents producing the magnetic field. The resulting vector map, sometimes called “an arrowmap” roughly mimics those currents under the surface which are parallel to the surface, which produced the field. Therefore, the purpose in performing the transformation is to allow a rough visualization of the underlying, parallel currents. The transformation was proposed by Cohen and Hosaka of the Biomagnetism group at MIT , then was used by Hosaka and Cohen to visualize the current sources of the magnetocardiogram .
