What is an MRI quizlet?

MRI: Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body.

What are the three principal components of an MRI system quizlet?

What are the three subassemblies of the gantry of a superconducting MRI system? The patient couch, the primary electromagnet assembly, and the various secondary electromagnets.

What are the factors that influence MRI scanner noise quizlet?

Noise is affected by magnitude in scanner, and by the patient's size and anatomy. Noise is expressed randomly in space and time.

How many sets of paired physical gradients are present in an MRI scanner?

Three sets of gradient coils are used in nearly all MR systems: the x-, y-, and z-gradients. Each coil set is driven by an independent power amplifier and creates a gradient field whose z-component varies linearly along the x-, y-, and z-directions, respectively.
