The lease with General Electric for a GoldSeal Revolution EVO EX scanner is for seven years and will cost the district about $871,300. The new scanner will be delivered in time to be installed in ...
This technology is the fastest generation of CT scanner to date. Third-generation spiral CT designs, especially those with 64 detector rows, 3×360°/sec rotation speeds, and designed for cardiac imaging, are largely replacing the EBT design from a commercial and medical perspective. However, electron beam CT still offers sweep speeds of ...
Mar. 26—By TARA WYATT Bluefield Daily Telegraph PRINCETON — A new and affordable CT scanner is now available for coronary CTA examination to those wanting reassurance with their cardiac health ...
Several methods that can reduce the exposure to ionizing radiation during a CT scan exist. [120] New software technology can significantly reduce the required radiation dose. New iterative tomographic reconstruction algorithms (e.g., iterative Sparse Asymptotic Minimum Variance) could offer super-resolution without requiring higher radiation ...
Compared to most other diagnostic imaging procedures, CT scans result in relatively high radiation exposure. This exposure may be associated with a very small increase in cancer risk. The question is whether that risk is outweighed by the benefits of diagnosis and therapy [8] The procedure has a low rate of finding disease.
This has the potential reduce the amount of X-ray dose from a contrast scan by removing the need for a reference scan before contrast injection. Although spectral CT is already clinically available in the form of dual-energy scanners, photon-counting CT offers a number of advantages.
A medical radiographic exposure is always initiated by a human operator but an AEC detector system may be used to terminate the exposure when a predetermined amount of radiation has been received. [1] The intention of AEC is to provide consistent x-ray image exposure, whether to film, a digital detector or a CT scanner.
Most radiation therapy is planned using the results of a 3D CT scan. A 3D scan largely presents a snapshot of the body at a particular point in time, however due to the time of the acquisition, in which the patient is likely to have moved in some way (even if only breathing), there will be an element of blurring or averaging in the 3D scan.
