WebApr 7, 2024 · Dynamic imaging addresses the recovery of a time-varying 2D or 3D object at each time instant using its undersampled measurements. In particular, in the case of dynamic tomography, only a single projection at a single view angle may be available at a time, making the problem severely ill-posed. In this work, we propose an approach, RED … WebSince its inception in 1971, the dramatic evolution of Computed Tomography (CT) has led to the steady growth of CT’s role in patient care. Canon Medical has pioneered many of the technological innovations defining the clinical expansion of CT, such as Area Detectors, Ultra-High Resolution, and Deep Learning Reconstruction.
