Russian researchers develop next gen cardiograph scanning

The Russian Quantum Center (RQC) is developing ultrasensitive sensors based on monocrystal garnet ferrite film to diagnose possible infarction developments in a patient, RQC  announced . 

Just recently, the Center began using a unique magnetic field free room with iron-nickel alloy walls that are said to be able to reduce penetrating magnetic fields by a factor of 1,000. The room is expected to enable researchers to calibrate and fine-tune their ultrasensitive sensors, a solution which the scientists want to bring to market to replace ultraconductive magnetic sensors physicians currently utilize in magnetic cardiograph scanning. The new room cost RQC a reported 275,000 euros. 

The effort led by a group of Dr. Vladimir Belotelov is said to have borne fruit already. The pioneering sensor samples are developed and need calibration for the product to be able to ‘ignore’ external magnetic fields. 

The researchers hope sensors like these will reach a sensitivity of about one femtotesla at a room temperature. The sensitivity would be enough to diagnose imminent infarction by pinpointing change in the heart’s magnetic fields. 

According to the Belotelov group’s estimates, the new magnetic modulation sensors will be about a hundred times easier on the pocket to make than any magnetic cardiograph scanning unit used today.
