Introduction to Computed Tomography

Abstract

A non-invasive imaging method called computed tomography (CT) uses X-rays to produce precise cross-sectional images of the body. In order to see interior structures, find anomalies, and direct interventions, it is frequently employed in medical diagnostics. When evaluating disorders including tumours, fractures, and vascular diseases, as well as imaging intricate anatomical regions, CT scans are especially useful. By offering precise cross-sectional images of the body, Computed Tomography (CT) is a crucial diagnostic imaging method that has transformed medical imaging. A thorough introduction to CT is given in this chapter, which also covers its technological underpinnings, historical evolution, and several medical diagnostics uses. Additionally, the chapter highlights the value of CT in a number of clinical settings, such as cardiology, neurology, oncology, and trauma care. CT has emerged as a vital tool in contemporary medicine due to its capacity to deliver comprehensive anatomical information and support accurate diagnosis. In summary, this chapter provides an overview of computed tomography's function in clinical practice and provides an awareness of its technical aspects as well as ongoing advancements.
