Results obtained by measurement of the weak magnetic fields associated with organs in the human body have significant potential for a number of areas in the health sciences. A substantial amount of recent research activity has therefore been directed toward the goal of making biomagnetic measurements of useful resolution in an ordinary laboratory environment. For certain simple types of measurements the major problems have been solved and systems developed to the point of clinical usefulness. In other important instances, e.g., measurement of fetal brain activity, the goal has been approached but not yet attained. This review discusses both general principles and practical considerations involved in the optimization of a measurement system. Particular attention is given to the new area of biomagnetic susceptometry which has attracted considerable clinical interest. Specific examples of state of the art biomagnetic measuring systems are discussed and the potential for further improvement assessed.
