MAGNETIC RESONANCE IMAGING MACHINE

摘要

The invention relates to the field of medical diagnostics and can be used in magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) for increasing the quality of diagnostics of the internal organs of humans and animals. By virtue of a metamaterial, which is used as an electromagnetic field amplifier, being made from a set of advantageously oriented conductors, it becomes possible to spatially rearrange magnetic and electric fields operated at radio frequencies. In particular, in the examined object area, the radio frequency magnetic field is resonantly amplified, which makes it possible to increase the signal/noise ratio in MRI and to obtain better quality images and/or to perform the MRI examinations more quickly as there is no need to accumulate the signal. The proposed design of the metamaterial makes it possible to distance the radio frequency electric field from the area where the examined object is located, therefore enhancing safety of MRI scanning.
