CT Scan in Description

Computed tomography (CT scan) is a method of non-destructive layered studies of object’s internal structure. It was offered in 1972 by Godfrey Hounsfield and Allan Cormack who were awarded with the Nobel Prize for the development of the method. The method is based on measuring and complex computer processing of the difference between the X-ray attenuation at different tissue density. Today, CT scan is major human tomography studies of internal organs using X-rays.

Modern CT scan is a sophisticated and complex software-hardware. Mechanical components and parts are made with the highest accuracy. Ultrasensitive detectors are used to register X-ray passed through the environment. Design and materials of detectors are constantly being improved. In the manufacture of CT scans, the most stringent requirements for the X-ray emitters are imposed. An integral part of the machine is an extensive software package that allows you to carry out the whole range of computer-tomography (CT studies) with optimal parameters, conduct post-processing and analysis of CT images. As a rule, the standard software package can be greatly expanded with the help of specialized programs tailored to the particular scope of each specific device.

From a mathematical point of view, the construction of the image is reduced to solving linear equations by the system. For example, to obtain the tomogram of the size of 200x200 pixels system includes 40,000 equations. There are specialized methods focused on parallel computing to solve such systems.

CT scan today is the leading method for the diagnosis of many diseases of the brain, spine, lungs and mediastinum, liver, kidney, pancreas, adrenal, aorta and pulmonary artery, heart, and other organs. CT scan can also be used as a method of primary diagnosis, and as a method of specifying when the preliminary diagnosis has already been diagnosed using ultrasound or clinical examination.

CT scan is a standardized method of diagnosis, so it is little affected by the physician conducting the study. All protocols of CT scan performance are carefully checked.

Ct scan is the best method for diagnosing diseases of the lungs and bones. With injecting the contrast agent CT scan allows to obtain high-quality three-dimensional images of the heart and blood vessels, including the coronary arteries and aortocoronary bypass grafts. Hospitalization and injection of catheter into the heart vessels are not required for these studies.

After special bowel preparation, virtual colonoscopy can be performed by CT scan (without introducing the endoscope intestine).
