Cone-beam spiral computed tomography (CT) is a medical imaging technology that has impacted healthcare since its development in the early 1990s.
[1][2] This technology offers advancements over traditional fan-beam CT, including faster scanning speed, higher image quality, and the ability to generate true three-dimensional volumes, even with contrast-enhancement.
It is estimated that the majority of the approximately 300 million CT scans performed annually worldwide use spiral cone-beam technology.
The concept of cone-beam spiral CT was first proposed by Ge Wang in 1991,[3] who also introduced algorithms for approximate image reconstruction.
The cone-shaped X-ray beam captures a large volume of data in a single pass, enabling the reconstruction of high-resolution volumetric and dynamic images.
