WebMar 23, 2024 · This same phenomenon is exploited in radiography and CT, by use of metal filters in order to "pre-harden" the x-ray spectrum and minimize low energy photons (see filters) 2. In CT, beam hardening from a very dense target (e.g. bone or iodinated contrast) may result in characteristic artifacts. WebMar 23, 2024 · The attenuated x-rays are detected on the opposite side by an x-ray detector, which has multiple dexels in the x and y-axis 2. Volume acquisition can thus be acquired with fewer rotations of the x-ray tube gantry. This differs from fan-beam CT, which uses a 2D fan-shaped x-ray beam in helical progression to acquire image data. list of ccs paneled providers

WebJan 22, 2024 · Dual-source CT contains two sets of x-ray tube and detector arrays, which are arranged in a single gantry perpendicular (90 degrees) to each other in the x-y plane ( Figure 7-1, A ). Dual-source CT has three main advantages over the single-source scanners, depending on the mode of scan acquisition. WebMar 23, 2024 · Tube arcing occurs when there is a short-circuit within the tube, typically from the cathode to the tube envelope. The result is a temporary loss of x-ray output and a localized artifact. A small amount of tube arching is not uncommon and modern scanners have automated processes to remove the artifact from the final images 1,2 .
