- A Magnetic Field Gradient Of 20 Mt Mis Combined With A Static Magnetic Field Of 1 Tesla A Crafted Radio Frequency Pulse 1 (20.82 KiB) Viewed 52 times
A magnetic field gradient of 20 mt mis combined with a static magnetic field of 1 Tesla. A crafted radio frequency pulse with a centre frequency of 42,576 Hz excites a bandwidth of 1.7 kHz. (a) If the magnetic field gradient is turned on while the radio frequency is pulsed, what is the resulting slice thickness of the image? (b) If the central frequency (00/21) of the crafted pulse is changed to 40,000 Hz, how far will the selected slice be from isocentre? (c) Comments your calculations, (Let y/2x - 42.576 Hz ml)
