Problems solved by technology

However, this patent uses a cylindrical magnetic resonance imaging, which limits the space of the object to be examined, so that it is impossible to arrange ultrasound treatment facilities more effectively (such as placing more than one transmitting probe), and it does not propose the use of high-energy focused ultrasound transmitters in a magnet environment more effective measures or improvements
