10. A 'H spin is located 10 cm away from the iso-centre of a 1.0 T system in the x-direction, 15 cm in the y direction and 0 cm in the z-direction. The following gradients are applied simultaneously: G. = 10mT/m, Gy = 20 mT/m and G. = 35 mT/m. a. What is the precessional frequency v in MHz at this point? (Remember: * = = = 42.58 MHZ/T) (5 points) b. What is the offset from the precessional frequency without gradients? (5 points)
