11-Channel Multipurpose Biomagnetic System for Operation in Unshielded Environment
Progress toward the realization of a medium size multipurpose biomagnetic system is described. Eleven second-order gradiometers are coupled with as many dc-SQUIDs manifactured in our laboratory. The geometry of the detecting coils consists of seven sensors arranged in a straight line and four sensors placed around the center. By means of this configurationit is possible to scan the chest or the abdomen with the seven aligned sensors, to measure the head with the seven central sensors whereas the whole system can provide significant information for “single shot” cardiomagnetic measurements in clinical studies.
