APPARATUS AND METHOD FOR SYNCHRONIZING CLOCKS BETWEEN DEVICES OF MAGNETIC RESONANCE IMAGING (MRI) SYSTEM
First Claim
1. A method of synchronizing clocks between a central controlling unit and a radio frequency (RF) coil which are connected to each other in a magnetic resonance imaging (MRI) system, the method comprising:
- receiving a first clock from the central controlling unit;
synchronizing a second clock of the RF coil with the received first clock; and
discontinuing the receiving of the first clock from the central controlling unit when the second clock is synchronized with the first clock.

Abstract
A method of synchronizing clocks between a central controlling unit and a radio frequency (RF) coil which are wirelessly connected to each other in a magnetic resonance imaging (MRI) system, which includes receiving a first clock from the central controlling unit, synchronizing a second clock of the RF coil with a received first clock, and discontinuing the receiving of the first clock from the central controlling unit when the second clock is synchronized with the first clock.
