CTS: – Computerised Tomography Scanner
“computed tomography scanners”( CTS), also called Computerized Axial Tomography (CAT), refers to a computerized x-ray imaging instrument from which a special beam of x-rays which is aimed at a patient, producing signals that are further processed by the machine’s computer to generate cross-sectional images—or “slices”—of the body. These tomographic images (slices) contain more detailed information than conventional x-rays. The slices are digitally “stacked” together to form a three-dimensional image of the patient after a number of successive slices are collected by the machine’s computer that allows for easier identification and location of basic structures as well as possible abnormalities or tumors.
The scanner was developed independently by and Dr. Alan Cormack and a British engineer Sir Godfrey Hounsfield. Nowadays, it has become a bastion for diagnosing medical diseases. Cormack and Hounsfield were jointly awarded the Nobel Prize in 1979. CT scan has commonly performed procedure in recent times and CTS have immensely improved patient comfort because a scan can be done quickly and painlessly. The non –invasive CTS have revolutionized medicine because of the higher-resolution images it delivers, which assist the doctor in making accurate diagnosis. CTS are found not only in hospital X-ray departments, but also in outpatient offices.
