The time varying magnetic field is created by the:

A 1.5-3T scanner must have homogeneity of 100 ppm or better.

What is the main advantage of using superconductive magnets over resistive magnets in MRI?

What type of shimming uses small ferromagnetic plates?

What is the role of bucking coils in active shielding?

The polarity of a gradient is determined by the direction of the current flowing through the coil.

The RF used in MRI is often referred to as B1.

What shielding material is commonly used to prevent external radio source interference in an MRI room?

The pulse generator module component of the computer system sends instructions related to timing, amplitude and the shape of transmitted RF pulses.

Gradients coils are in a 3-terminal arrangement of A, B and C.
