The introduction of computed tomography (CT) in 1972 was among the most significant development in medical imaging since the discovery of X-rays in 1895. In addition, the innovation of computationally reconstructing tomographic images from projection data significantly influenced the development of other medical imaging modalities, such as magnetic resonance imaging and single photon and positron emission tomography. With the advent of helical and multi-detector-row CT (MDCT) scanners in the 1990s and 2000s along with innovations in cone-beam CT (CBCT) in many forms, CT gained unmatched speed and adaptability for volumetric imaging, leading to widespread use for diagnostic imaging, emergency examination, image-guided interventions, treatment planning, and monitoring of therapeutic response.
