Methods: The scanners investigated were a newly installed Siemens Biograph mCT PET with 64-slice SOMATOM Definition AS CT using sinogram affirmed iterative reconstruction (SAFIRE) and two GE Discovery 710 PET scanners with 128-slice Optima 660 CT using adaptive statistical reconstruction (ASiR). Following exploratory phantom work, 33 adult
Benefits. 128-slice imaging capability: The Definition Edge 128 is capable of capturing up to 128 slices per rotation, which means it can provide high-resolution images of the body in a shorter amount of time than CT scanners with fewer slices. Dual Energy Imaging: This advanced technology allows for differentiation of structures with similar
Coronary artery calcium (CAC) is a marker of overall coronary atherosclerotic burden in an individual. As such, it is an important tool in cardiovascular risk stratification and preventive treatment of asymptomatic patients with unclear cardiovascular disease risk. Several guidelines have recommended the use of CAC testing in shared decision making between the clinician and patient. With
P 1.0 results in decreased patient dose but also decreased image quality (fewer projections are obtained, resulting in lower SNR). A pitch of
The hospital has replaced its 64-slice CT scanner with a 128-slice CT scanner, the GE Revolution CT ES. “Slice” refers to the number of rows of detectors the scanner has. The more detectors, the bigger the volume coverage and faster scanning times. With the new scanner, the Radiology team can also perform 256-slice reconstruction.
Background A significant proportion of the radiation dose from a PET-CT examination is dependent on the CT protocol, which should be optimised for clinical purposes. Matching protocols on different scanners within an imaging centre is important for the consistency of image quality and dose. This paper describes our experience translating low-dose CT protocols between scanner models utilising
Computed Tomography. Introducing groundbreaking CT products and technologies for decades, we are known as the innovation leader in this field. Our portfolio shows unique arguments with regards to artificial intelligence, low dose, workflow optimization and image quality. With this, we enable you to increase value and be at the forefront in CT.

Siemens Definition Overview. The Siemens Definition is a reliable and versatile imaging device that delivers high-quality images with minimal radiation exposure. With its unique Dual Energy mode and fast scanning times, this scanner can differentiate between different organs in the body, producing images with excellent spatial resolution and
The Siemens Definition DS 128 offers more definition of detail, resolution, and clinical information. Siemens z-Sharp tube technology uses a flying focal spot to create two x-ray beams simultaneously hitting a 32-row detector, effectively producing 64-slice scans. The Definition DS is one of the quickest 64-slice systems available along with temporal resolution of 83 msec […]
