CT Scan - Computed Tomography
Spiral computed tomography uses roentgen rays
(X-rays) to get detailed images of the inside of the human body like never
before.
As a result of advanced computer processing,
diagnostic images can be created for any part of a patient’s body. Enough data
can be collected in a CAT scan for the rendering of an advanced three-dimensional
reconstruction of the examined tissue or organ.An
X-ray lamp and detectors suspended on opposite sides of a perfectly round hoop
are the main components of a CAT scanner. Entering the CAT scan on a special
table, the patient is situated between the lamp and detectors. The X-ray lamp
generates radiation, which passes through the patient’s body and is picked up
by detectors. The fact that X-rays are differently impaired by individual
organs/tissues of the body forms the collection basis for the image. The
detectors are able to measure the level of this differential weakness and
create a digital image of the results. The amount of data attained during the
examination has grown due to the application of modern detectors, which has
given greater processing possibilities. This means that, after performing an
examination, even when the patient has already left the studio, we can use the
received data to get additional and alternative renderings of the examined
area. They are usually two and three dimensional images of examined structures,
and in the case of the cardiovascular system, the images are similar to
subtractive angiography. It is also possible to make three-dimensional images
of the interior of organs using the light/clearance system (such as: blood
vessels, stomach, intestines, trachea, bronchial tree, and even the inside of
the middle ear). Such reconstructions are called multi-surface, three-dimensional
or virtual endoscopy.CAT scan recommendations for orthopaedic patients:
