The first-in-Russia superconducting magnet resonance 1.5 Tesla imaging system for high-precision medical diagnostics

The first-in-Russia 1.5 MRI system for high precision medical diagnostics is developed and manufactured. It is based on own 1.5 T superconducting magnet with warm bore 90 cm built in cooperation between FIAN and Russian RTI company (Moscow). The field homogeneity is about 2 ppm in 40 cm sphere; the magnet field stability is 0.01 ppm/h which equals the standard value of the class MRI systems. MRI allows to obtain images of the layers in the 3 main planes - axial, sagittal and frontal - as well as on inclined planes with an inclination of up to 45°. The minimum thickness of the section plane in 2D mode is not more than 2 mm, in 3D mode - no more than 0.5 mm. Spatial resolution in the image plane at a thickness of 5 mm layer structure allows to distinguish with the linear dimensions no more than 0.4 mm. The technical documentation is ready for production.
