Producing MRI Scans
The powerful computer
system of the MRI scanner converts the signal that it receives from the antenna
into understandable images and it does so in either 2-D or 3-D, depending on the
requirements of the observer. The computer system creates images and scans
using a specific mathematical formula known as the ‟Fourier Transformˮ, which
brings us to the ‟imagingˮ part of the device. The images show a layout of
various tissue types that have been scanned in a particular part of the body.
The MRI system uses dyes that alter the magnetic field in the tissue being
examined. Since normal and abnormal tissues respond differently to this
alteration, the different signals allow the doctors to identify exactly what
and where the problem is within the body. This process can be thought of as the
following: If Alteration = A, then Normal Cells = B; however, if Alteration =
A, then Abnormal Cells = other variety of results.
In addition, the MRI system
uses more than 250 shades of gray to depict and distinguish these abnormal
tissues. This allows doctors to examine and identify different kinds of
diseases much more efficiently than they could without the contrast.
Also, the
MRI scanner can create a variety of image types and angles. This device can
produce axial images, which gives you a view of the body in accordance to the
x-, y- plane, allowing the observer to have a general observation of the
certain body part from either the top or the bottom. It can also create sagitall
images, which allows you to examine the body part from the sides. MRI technology
can create coronal images as well, which is a 3-D observation of the different
layers of tissue all in relation to one another.

The best part about MRI scanning is that all these different kinds of
images and scans can be produced without the patient actually having to
move inside the tube in order for the observer to get the picture that he
requires. The observer can simply adjust the machines settings and be able
to record the very best image that he needs.
