DIGITAL RECEIVER COIL WITH BUILT-IN PHASE NOISE RECEPTION INDICATOR Russian patent published in 2019 - IPC A61B5/55 G01R33/36 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, specifically to means of visualizing the internal organs of the body. Method of detecting phase noise when forming an image of magnetic resonance imaging comprises steps, receiving a reference signal from the imaging device by the magnetic resonance imaging (MRI) device, the MRI device using the wireless communication coils propagating image signals based on the digitizer clock generator to obtain image data, used by the imaging device for generating an MRI image, formed on the basis of a system clock generator, to which it is desirable to distribute image signals, separating the initial reference signal by the MRI device to the first and second reference signals, adjusting the phase shift of the second reference signal by the MRI device to form an orthogonal reference signal, the MRI device determines the product of the first reference signal with an orthogonal reference signal, and the MRI device determines an indication indicating the reliability of the image data based on the product. Magnetic resonance imaging (MRI) device comprises a digitizer clock generator, wireless communication coils propagating image signals based on a digitizer clock generator, to obtain image data, a receiver configured to receive an initial reference signal from a display device formed on the basis of the system clock generator, and a processor.

EFFECT: use of inventions makes it possible to synchronize a clock generator of a digitizer of a magnetic resonance imaging device (MRI) with a system clock generator of a visualization device, which provides more accurate scanning.
