how do you calc Gradient slice selection
The actual timing diagram for a volume imaging pulse sequence looks like this. There is a volume selection RF pulse and gradient which rotates only those spins in the imaged volume of the object. This combination of pulses is equivalent to a slice selection combination except the slice thickness can be 10 or 20 cm.he timing diagram for an inversion recovery imaging sequence has entries for the RF pulses, the gradients in the magnetic field, and the signal. A slice selective 180 o RF pulse is applied in conjunction with a slice selection gradient.
