Abstract
This article presents studies carried by laboratory of Biomedical and Nucleonic Computer Systems. Our research concerns improvement of quality of imaging in low-field MRI scanner with field strength of 0.23 T as well as development of techniques of proton-electron dual resonance imaging and hyperpolarization of noble gases. Achieved results may contribute to improvement of multiple techniques of medical diagnostics, in particular functional study of lungs and heart as well as brain perfusion.
