NON-CONTACT ANALYSIS OF MAGNETIC FIELDS OF BIOLOGICAL OBJECTS:
ALGORITHMS FOR DATA RECORDING AND PROCESSING

Abstract. Based on low-temperature SQUID sensors, an ultra-sensitive magnetometric system has been created for the analysis of nanoparticles in biological objects. The main features of the SQUID magnetometric system and information technology during registration and analysis of magnetic signals from organs of laboratory animals are considered. Experimental data on the operation of the magnetometric system and algorithms of data recording and processing in the study of physical models (small animals) with nanoparticles are presented.

Keywords: SQUID sensor, magnetometric system, information technology, inverse problem, biological objects, nanoparticles.
