2. Sensible Solutions for Refurbished Radiology
There are nearly 40 million MRI scans performed every year in the United States, making it a true
workhorse of medical imaging systems. They also account for well over $100 billion in revenue. With
so much at stake, it’s important to understand how MRIs work. Let’s take a look at the components
of MRI equipment.
3. Sensible Solutions for Refurbished Radiology
At the heart of every MRI system is a large magnet, producing a very strong magnetic field. To create
the image, the patient’s body is placed in that magnetic field during the imaging procedure. There
are two distinct effects that work together to create the image: Tissue Magnetization and Tissue
Resonance.
Tissue Magnetization: As the patient is placed in the magnetic field of an MRI, the tissue becomes
magnetized temporarily because of the alignment of the protons. This very low-level effect
disappears when the patient is removed from the MRI’s magnetic field.
The Magnet
4. Sensible Solutions for Refurbished Radiology
Because the normal and pathologic tissues become magnetized to different level or changes their
level of magnetization at different rates, the MRI can distinguish between the different types of
tissues.
Tissue Resonance: The MRI’s magnetic field causes tissue to “tune in” or resonate at a very specific
radio frequency. Which is why the procedures is called Magnetic Resonance Imaging. The nuclei,
typically protons within the tissue, resonate. In the presence of a strong magnetic field the tissue
resonates in the RF range, which causes tissue to function as a tuned radio receiver and transmitter
during the imaging process. Two-way radio communication between the tissue in the patient’s body
and the equipment results in the MRI image.
5. Sensible Solutions for Refurbished Radiology
At any point within a magnetic field, you’ll find two primary characteristics: field direction and field
strength.
Field Direction: On the surface of the earth, the direction of the earth’s magnetic field is specified
with reference to the north and south poles. However, this north-south designation is not usually
applied to magnetic fields used for imaging. Most electromagnets used for imaging produce a
magnetic field that runs through the bore of the magnet and parallel to the major patient axis.
The Magnetic Field
6. Sensible Solutions for Refurbished Radiology
As the magnetic field leaves the bore, it spreads out and encircles the magnet, which creates an
external fringe field. This can be a source of interference with other devices and is usually contained
by some form of shielding.
Field Strength: Each point within a magnetic field has a particular strength or intensity. It’s expressed
in either units of tesla (T) of gauss (G), with 1.0 T being equal to 10,000 G or 10 kG. At the earth’s
surface, the magnetic field is relatively weak and has a strength of less than 1 G. For imaging,
magnetic field strengths are the range of 0.15 T to 1.5 T.
7. Sensible Solutions for Refurbished Radiology
MRI requires a very uniform magnetic field with respect to strength. Field homogeneity is affected by
magnet design, adjustments and environmental.
conditions. Imaging usually requires a homogeneity (field uniformity) on the order of a few parts per
million (ppm) within an imaging area. High homogeneity is obtained by the process of shimming.
Homogeneity
8. Sensible Solutions for Refurbished Radiology
Several different types of magnets can be used to produce a magnetic field, each with its own
advantages and disadvantages
Magnets
Superconducting Magnets
Most MRI systems utilize superconducting magnets. A superconducting magnet is capable of
producing a much stronger and stable magnetic field than resistive fields and permanent fields.
9. Sensible Solutions for Refurbished Radiology
A superconducting magnetic is an electromagnet that operates in a superconducting state.
A superconductor is an electrical conductor (wire) that has no resistance to the flow of an electrical
current, which means that tiny superconducting wires can carry very large currents without
overheating. This is typical of more conventional conductors like copper. Strong magnetic fields are
made possible by the combined ability to construct a magnet with many loops or turns of small wire
and the use of large currents.
10. Sensible Solutions for Refurbished Radiology
To achieve super-conductivity, the conductor or wire must be fabricated from a special alloy and
then cooled to a very low temperature. The typical magnet consists of small niobium-titanium (Nb-Ti)
wires imbedded in copper, which has electrical resistance and functions as an insulator around the
Nb-Ti superconductors. The electrical current flows through the superconductor without dissipating
any energy or producing heat. If, however, the temperature of the conductor should ever rise above
the critical superconducting temperature, the current will begin to produce heat and the current will
be rapidly reduced, resulting in the collapse of the magnetic field. This undesirable event is known as
a quench.
11. Sensible Solutions for Refurbished Radiology
Superconducting magnets are cooled with liquid helium; however the coolant must be replenished
periodically. Most superconducting magnets are in the form of cylindrical or solenoid coils with the
strong field in the internal bore. Because of the relatively small diameter and the long bore, it can
produce claustrophobia in some patients. To reduce this concern, superconducting magnetic design
is evolving to more open patient environments.
12. Sensible Solutions for Refurbished Radiology
A resistive type magnet is made from a conventional electrical conductor like copper. The name
“resistive” refers to the inherent electrical resistance that is present in all materials except for
superconductors. When a current passes through a resistive conductor to produce a magnetic field, it
produces heat, which limits this type of magnet to relatively low field strengths.
Resistive
13. Sensible Solutions for Refurbished Radiology
MRI can be performed with a non-electrical permanent magnet, which doesn’t require electrical
power or coolants—but this type of magnet is limited to relatively low field strengths.
Both resistive and permanent magnets are designed to produce vertical magnetic fields that run
between the two magnetic poles. Possible advantages include a more open patient environment and
less external field than superconducting magnets.
Permanent
14. Sensible Solutions for Refurbished Radiology
When an MRI system is in a resting state and not producing an image, the magnetic field is uniform
or homogenous over the targeted region of a patient’s body. During the imaging process, the filed
must be distorted with gradients. Think of a gradient as a change in field strength from one point to
another in a patient’s body. These gradients are produced by a set of gradient coils contained within
the magnet assembly. The gradients are turned on and off many times during an imaging procedure,
which creates the noise that comes from a magnet.
Gradients
15. Sensible Solutions for Refurbished Radiology
Imaging magnets contain three separate sets of gradient coils. The coils are oriented so that
gradients can be produced in three orthogonal directions (x, y and z directions). Two or more of the
gradient coils can also be used together to produce a gradient in any desired direction.
Gradient Orientation
Gradient Functions
Gradients are used to perform a variety of different functions during an image acquisition process.
These gradients create the spatial characteristics by producing slices and voxels.
16. Sensible Solutions for Refurbished Radiology
All gradient echo imaging methods use a gradient to produce an echo events and signal. Gradients
are also used to produce a type of image contrast (phase contrast angiography) for vascular imaging.
They are also used as part of techniques to reduce image artifacts.
Gradient strength is expressed in terms of the change in field strength per unit of distance. These
typical units are millitesla per meter (mT/m). The maximum gradient strength that can be produced
is a design characteristic of a specific imaging system.
Gradient Strength
17. Sensible Solutions for Refurbished Radiology
he gradient has to be able to change rapidly for certain function. The time required for a gradient to
reach its maximum strength is called the risetime and the rate at which the gradient changes with
time is called the slew-rate.
Risetime and Slew-Rate
Eddy Currents
These are electrical currents that are induced or generated in metal structures or conducting
materials that are within a changing magnetic field.
18. Sensible Solutions for Refurbished Radiology
Eddy currents are produced in some metal components of the magnet assembly by strong, rapidly
changing magnetic fields. Because eddy currents create their own magnetic fields that interfere with
the imaging process they are undesirable. Gradients are designed to minimize eddy currents by using
special gradient shielding or electrical currents that control gradient currents in a way that can
compensate for the eddy current effects.
