Abstract
A magnetic resonance imaging apparatus according to an embodiment includes a main apparatus and a coil apparatus that is separate from the main apparatus. The main apparatus transmits a wireless signal acquired by frequency-modulating a binary signal based on a first clock signal generated from a first system clock. The coil apparatus generates a second clock signal by dividing the received wireless signal, and generates a second system clock from the generated second clock signal. Frequencies of the second system clock and the first system clock are the same.
