computed tomography,dual energy CT,ultra high-resolution
Clinical X-ray computed tomography (CT) has undergone remarkable technological advances. In addition to providing high-resolution three-dimensional anatomical information, CT has enabled cardiac imaging through gantry rotation times of less than 0.3 s. Functional and quantitative imaging has also progressed with dual-energy scanning for material discriminations and photon-counting detectors, representing the most advanced form of X-ray detection. These developments have established CT as a leading modality in diagnostic imaging, offering both morphological and functional information. This lecture will provide an overview of the technological evolution of CT and introduce an ultra-high-resolution extremity CT system with a spatial resolution of 0.08 mm. Developed through the increasing specialization of CT technology, this scanner enables unprecedented visualization of fine anatomical structures in the extremities.
