Siemens adds to CT presence at British hospital
The 850-bed Royal Liverpool University Hospital in Liverpool, England, has installed two Somatom Definition AS and AS+ CT scanners from Siemens Healthcare, joining a Somatom Sensation 16 already on site.

The Somatom Definition AS has been installed into the radiology department for outpatient, cardiac and colonography cases, the company said. The AS+ version has been installed into the accident and emergency department for use in trauma, emergency intervention and brain perfusion imaging.

Siemens said that its Somatom Definition AS+ is an adaptive scanner, designed for neurological and cardiac imaging, obtaining fast coverage with 128 slices per rotation. With a temporal resolution of 150 ms, images are free from movement artifacts and show the fine anatomical details to assist with diagnosis and treatment planning. The Adaptive 4D Spiral capabilities of the Definition AS+ gives whole organ coverage in 4D for tumour perfusion, allowing clinicians to see an entire picture instead of preselecting a narrow section to evaluate for perfusion defects.

The Somatom Definition AS is adaptable, speeding up exams for patients such as children, the obese and those suffering from claustrophobia. It also combines components, such as the Adaptive Dose Shield, which block radiation.
