FIELD: physics, navigation.
SUBSTANCE: usage: for transmitting or receiving antenna of the aircraft in the decimeter wavelength range. The invention is that the magnetic resonance scanner includes the main magnet, gradient coils and the gradient coils controller, one or more radio-frequency reactor, the RF transmitter, RF receiver and one or more processor. The main magnet generates the field B0. Gradient coils and the gradient coils controller form gardients through the field B0. One or more RF coils transmit impulses B1, receive magnetic resonance signals. The RF transmitter sends impulses B1 to the RF coils for exciting the resonance and to manipulate it. The RF receiver demodulates the received resonance signals in the data line. One or more processor is connected with the controller of the gradient coils, the RF transmitter and the RF receiver, and is programmed to control the RF transmitter and the controller of the gradient coils for implementing of interleaved multislice 2D sequences of imaging, that in each of the numerous repetitions (TR) generate the first and the second line of the navigation data and at least one line of the image data for each of the numerous sections. One or more processor is further programmed: to reconstruct the first navigation data lines of the numerous sections into the first projection navigation image, to reconstruct the second navigation data lines of the numerous sections into the second navigation image; and to compare successive projection navigation images for detection and correction of the 3D movement.
EFFECT: invention ensures the rapid motion detection and correction thereof.
