Dual source CT is an advanced scanner with a two X-ray tube detector system, unlike conventional single tube systems. [15] [16] These two detector systems are mounted on a single gantry at 90° in the same plane. [17] Dual Source CT scanners allow fast scanning with higher temporal resolution by acquiring a full CT slice in only half a rotation.
The new dual-source CT scanner is an intrinsic part of that mission. For patients with troubling symptoms of chest pain and/or abnormal EKGs we now have an amazing tool to render quick and ...
Dual-energy imaging, i.e. imaging at two energy levels, is a special case of spectral imaging and is still the most widely used terminology, but the terms "spectral imaging" and "spectral CT" have been coined to acknowledge the fact that photon-counting detectors have the potential for measurements at a larger number of energy levels. [2] [3]
As an example, each mm 2 of a CT detector may receive several hundred million photon interactions per second during a scan. [4] To avoid saturation in areas where little material is present between the X-ray source and the detector, the pulse resolving time must be small compared to the average time between photon interactions in a pixel.
X-ray computed tomography operates by using an X-ray generator that rotates around the object; X-ray detectors are positioned on the opposite side of the circle from the X-ray source. A sinogram (left) and an image sample (right). [1] Picture of a CT scout (scanogram or topogram) as used for planning every scan slice.
Though CT uses a higher amount of ionizing x-radiation than diagnostic x-rays (both utilising X-ray radiation), with advances in technology, levels of CT radiation dose and scan times have reduced. [9] CT exams are generally short, most lasting only as long as a breath-hold, Contrast agents are also often used, depending on the tissues needing ...
Electron beam computed tomography (EBCT) is a fifth generation computed tomography (CT) scanner in which the X-ray tube is not mechanically spun in order to rotate the source of X-ray photons. This different design was explicitly developed to better image heart structures that never stop moving, performing a complete cycle of movement with each ...
