Computed Tomography (CT) is a widely used medical imaging modality that generates cross-sectional images of the human body using X-rays and advanced computer algorithms. The CT generation process involves the acquisition of multiple X-ray projections from different angles, followed by image reconstruction techniques such as filtered back projection (FBP) or iterative reconstruction (IR) to produce high-resolution images. Technological advancements have led to the development of multi-detector CT (MDCT) and dual-energy CT (DECT), improving spatial resolution, image contrast, and diagnostic accuracy while reducing radiation exposure. The continuous evolution of CT imaging plays a crucial role in disease diagnosis, treatment planning, and interventional procedures across various medical specialties.
