The Scenaria SE 64/128 CT is available as a 64 or 128 slice model, with available on site upgrade from 64 to 128-slice capabilities. Scenaria SE provides enhanced workflow speed and ease of use to meet the needs of busy CT facilities. Greater patient access and comfort are achieved by combining a wider 75cm aperture, wide 48cm tabletop, 88cm The resulting maximum scan speed for 128-slice DSCT is 458 mm/s and even 737 mm/s for 192-slice DSCT. At the maximum pitch, this scan mode delivers a temporal resolution of ~rotation time/4 since no redundant data are acquired. Lowering the pitch also lowers the temporal resolution. CT or CAT scan is performed in a radiology center. As the scan machine uses radiations and magnetic fields to capture pictures, ensure that you do not wear any metallic accessories around your body. Metallic accessories can interfere with the working of the machine and can also affect images that need to be generated.

Research shows that this kind of radiation may damage your DNA and lead to cancer. But the risk is very small – your chances of developing P <1.0: there is x-ray beam overlap; i.e. a volume of tissue is irradiated more than once per scan; Thus a pitch >1.0 results in decreased patient dose but also decreased image quality (fewer projections are obtained, resulting in lower SNR). A pitch of <1.0 results in better image quality, but a higher patient dose. Multislice CT (MSCT) Materials and methods: Two consecutive cohorts of fifty patients underwent CCTA by high-pitch spiral scan mode using 128 or 192-slice DSCT. The 192-slice DSCT system has a more powerful roentgen tube (2 × 120 kW) that allows CCTA acquisition at lower tube voltages, wider longitudinal coverage for faster table speed (732 m/s), and the use of 64 and FineRecon 128 slice Slice thickness: 0.625 –10mm FOV: 20 – 500mm, by 1mm steps Matrix: 512 x 512 Immediate preview recon Image reconstruction time: up to 30 images/second (depending on recon parameters) Immediate image review CT number range: -128,768 to +128,767 Image Display and Analysis The integrated SPECT-CT acquisition console employs a Graphic User Interface for exam scheduling, scan acquisition, CT reconstruction and scan QC as well as utilities for protocol editing, routine quality control and analysis and networking, including: • Universal connectivity via DICOM 3.0 (as per DICOM conformance 3.2 Conventional 64-slice CT scanners Multi-slice CT scanners combine the use of X-rays with computerised analysis of series of 2D X-ray images to create 3D images. The technology has been rapidly advancing, with 4-slice CT scanners first appearing in 1998, 16-slice scanners in 2001 and 64-slice scanners at the end of 2004. Multi-slice CTCA mMDcC.
