RECORDING DEVICE WITH PIEZOELECTRIC MOTOR USED FOR PLATEN DRIVE FOR ENVIRONMENTS WITH STRONG MAGNETIC FIELDS Russian patent published in 2016 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: printing device comprises a print head, piezoelectric motor configured to feed paper through the print head, primary and secondary control boards connected to each other and the piezoelectric motor. A magnetic resonance imaging system comprises a primary magnet, gradient coils, radio-frequency coils, a controller and printing device. A method for providing information printing in the magnetic field consists in controlling the patient's physiological data, printing the controlled physiological data on paper, generating control signals by means of a mechanical step motor and generating piezoelectric excitation signals. A method for controlling the magnetic resonance imaging system consists in generating a static magnetic field, applying gradient magnetic fields, exiting radio-frequency coils, collecting information and printing the information in the strong magnetic field.

EFFECT: using the invention enables to print information in a close proximity from the magnetic resonance system with introducing no channels or circuits from long connections.
