True or False: The magnetic field strength of an MRI system can be determined by its size.

The statement that the magnetic field strength of an MRI system can be determined by its size is false. The magnetic field strength of an MRI system is primarily determined by the design and engineering of the MRI machine, specifically the type of magnets used and how they are configured, rather than the physical dimensions of the machine itself.

While certain aspects of size might influence other factors, such as the type of magnet that can be incorporated or how the system is constructed, they do not dictate the magnetic field strength. For example, a smaller MRI machine can still utilize powerful magnets to achieve strong field strength, while a larger machine may have less potent magnets. Therefore, the concept that size directly correlates with magnetic field strength does not hold true in the context of MRI technology.
