Computer tomography, also known as a CT scan, is an x-ray process wherein numerous views of an affected area are taken and sent electronically for computer generated analysis. Afterwards, a three-dimensional view of the affected area can be developed. The first prototypes of a CT scan were first developed in the United States during the 1960. Since then, this computer controlled x-ray apparatus has made significant technological advances.
The most modern CT machine in use is the multi-slice spiral computer tomography (MSCT) and one is in operation in our practice. With this machine, radiation exposure can be as little as 50 microseconds, resulting in a significant reduction in misdiagnosis that can occur if a patient moves during the examination process. The multi slice spiral computer tomography is so precise that it can accurately produce a picture of an affected area even when the exposure is a fraction of a millimetre off, for example, with a beating heart.
Using this method, the examine physician is able, using the CT scans, to make a proper diagnosis of a 'virtual patient'.
