Abstract :
To use fetal magnetocardiography for diagnostic purposes, it is important to know the requirements for the instrument. One of the questions to be answered is how sensitive the fetal magnetocardiograph must be. In this paper the requirements are discussed and a highly sensitive magnetocardiograph, that is optimized for fetal magnetocardiography in a magnetically shielded room, is presented
