Computed Tomography is a specialized X-ray imaging technique. It may be performed “plain” or after the injection of a “Contrast Agent”. CT creates the image by using an array of individual small X-Ray sensors and a computer. By spinning the X-Ray source and the sensor/detectors around the patient, data is collected from multiple angles.
A computer then processes this information to create an image on the video screen. These images are called “sections” or “cuts” because they appear to resemble cross-sections of the body. This technique eliminates the problem of conventional X-rays, where all the shadows overlap. Don’t worry though, the patient is not actually “cut”. Because it does use X-Rays to form the image, this computerized technique has some limitations that are similar to those for plain film radiographs.
Of course, this specialized imaging modality is tun by electricity, just like any other x-ray machines. Special electrical installations are required, thus special electric wirings, like twin & earth are installed. For more information, you can ask your electrical engineers regarding this.
