1. The system of magnetic resonance imaging, which contains an ultrasound system (118) for generating ultrasonic waves; wherein the ultrasound system includes an ultrasound window (130); and the ultrasonic window is adapted to receive the subject, while the magnetic resonance imaging system is configured (100) to detect a gas bubble (124, 148, 304, 306, 404, 406) within the imaging volume (108), while the system is magnetically -resonant imaging includes: - a magnet (102) adapted to generate a magnetic field for orienting the magnetic spins of the subject's nuclei (104) located within the visualization volume; - a radio-frequency system (110, 112) adapted to receive data (160, 164) magnetic re On the other hand, the radio-frequency system comprises a radio-frequency transmitter (112) and a radio-frequency coil (110); - a magnetic field gradient coil (114) adapted for spatial coding of the nuclear magnetic spins within the visualization volume; - a magnetic field gradient coil power source (116) adapted to provide coil current with a magnetic field gradient; and - a computer system (132) adapted to construct an image from magnetic resonance imaging data and to control the operation of the magnetic resonance imaging system, while the computer system is adapted to detect a gas bubble within the visualization volume using a magnetic resonance image (162, 166, 300, 400), constructed from magnetic resonance imaging data, and the ultrasound system is configured to
