 | Symko, Orest George | Discrete spatial filtering with SQUID gradiometers in biomagnetism | First-, second-, and third-order gradiometers used in detecting biomagnetic signals are analyzed as spatial niters. Their transfer functions independent of the source to be measured are presented and both the magnitude and phase characteristics of the transfer functions are analyzed. The distortion ... | Spatial filtering; SQUID gradiometers; Fourier transform | 1986 |

 | Symko, Orest George | Spatial Fourier transform method for evaluating SQUID gradiometers | A simple method of measuring the spatial transfer function of a gradiometer, consisting of a flux transformer coupled to a SQUID, is presented and it is compared with theoretical predictions. Based, on this approach, a new method of reporting a gradiometer's performance is proposed; the rejection fa... | Spatial Fourier transform; SQUID gradiometers; Evaluation; Spatial transfer function | 1987 |
