Transmission Computed Tomography (CT) is a medical imaging technique that involves capturing detailed cross-sectional images of the human body using X-ray radiation. It utilizes a specialized X-ray machine that rotates around the patient, capturing a series of X-ray images from various angles. These images are then processed by a computer to generate highly detailed cross-sectional images of the body, providing valuable diagnostic information.
In Transmission CT, X-rays are transmitted through the body, and the intensity of the transmitted X-rays is measured by detectors positioned on the opposite side. The X-ray attenuation, or reduction in intensity, caused by different tissues and structures within the body provides information about the composition, density, and shape of these structures.
The computer processes the acquired data and constructs detailed 2D or 3D images, called tomographic slices, which can be viewed from various angles. These images allow healthcare professionals, such as radiologists and physicians, to visualize internal organs, tissues, and abnormalities with high precision.
Transmission CT is widely utilized in the field of medical imaging for diagnosing and monitoring a variety of conditions, including fractures, tumors, organ abnormalities, and cardiovascular diseases. It provides valuable information regarding the location, size, shape, and composition of abnormal structures, aiding in the formulation of treatment plans and surgical interventions.
The accuracy, non-invasiveness, and versatility of Transmission CT make it an essential tool in modern medical practice, enabling early detection and accurate diagnosis of numerous medical conditions.
