Mayo Clinic and Siemens install first SOMATOM Sensation Open CT system with 40 slices

Malvern 14 June 2005Mayo Clinic in Rochester, Minnesota, is the first medical facility to install the SOMATOM Sensation Open computed tomography (CT) system with 40-slice technology. An optional high-capacity patient table, developed as part of the CT Clinical Innovation Center partnership between Mayo Clinic and Siemens Medical Solutions, was installed to offer advanced CT imaging capabilities for bariatric patients. The SOMATOM Sensation Open will be used for image-guided interventional procedures, and cancer and routine diagnostic CT imaging.

With an 82-centimeter large gantry bore and 82-centimeter extended field of view, the SOMATOM Sensation Open increases accessibility and simplifies scanning of large patients while allowing visualization of the entire anatomy, improving interventional CT, radiation therapy planning, and routine diagnostic examinations. Additionally, the new high-capacity patient table allows the scanning of patients weighing up to 615 pounds, compared to 440 pounds for conventional patient tables.

"With these features, the SOMATOM Sensation Open is ideally suited for our very heavy patients and our Bariatric Surgery Programme", stated Cynthia McCollough, Ph.D., associate professor of radiological physics, Mayo Clinic College of Medicine. "The system is a high performance CT scanner that provides a large gantry opening and large reconstruction field of view with a high-capacity patient table. In addition, the STRATON tube provides the X-ray output needed for high-quality images in very large patients. These are exactly the clinical and technical attributes we were seeking especially for bariatric care and image guided interventions."

The SOMATOM Sensation Open's optional CARE Vision CT software automatically reduces radiation dose to both physician and patient in CT-guided interventions such as drainages, biopsies, or pain therapy. Included in the CARE Vision package, HandCARE automatically switches off the X-ray beam at user-selectable scan projections, thus minimizing direct radiation exposure of the surgeon or radiologist's hand during intervention. CARE View software facilitates the simultaneous display of three contiguous slices directly at the patient table, allowing the physician to see the travel path of a needle or probe in real time.

Experts from Mayo Clinic will participate in the final clinical assessments, essential for a successful launch of the new 40-slice feature and the high-capacity patient table. The installation of the SOMATOM Sensation Open is part of an agreement between the Mayo Clinic and Siemens for the delivery of eight high-end CT systems, including seven SOMATOM Sensation 64 scanners.

"Siemens SOMATOM Sensation Open represents a huge advancement in CT by providing medical professionals with easy access to patients during interventional procedures in addition to advanced speed and image quality", stated Bappa Choudhury, vice president, CT Division, Siemens Medical Solutions. "This technology represents Siemens' dedication to our customers' need for faster, more accurate and efficient CT technologies."

Based on the latest Siemens CT technology, the SOMATOM Sensation Open is the first large bore 40-slice CT system, featuring a 0,5 second gantry rotation speed and Siemens' proprietary z-Sharp Technology. An electron beam is accurately and rapidly deflected, creating two alternating and overlapping X-ray projections reaching each detector element. This doubles the scan information without a corresponding increase in dose, resulting in substantially enhanced spatial resolution and image quality. z-Sharp Technology firmly established a new benchmark for diagnostic excellence, enabling sub-millimeter acquisitions with 40 slices per rotation, the virtual elimination of spiral artifacts, and the industry's highest level of isotropic resolution of below 0,4 millimeters.

The SOMATOM Sensation Open delivers a new level of diagnostic support for the care of cancer patients, radiation therapy planning, CT-based trauma examinations, interventional procedures and imaging of bariatric patients with excellent performance in routine and advanced CT examinations. First introduced as a 16-slice system at the Radiology Society of North America (RSNA) 2003, worldwide shipment of the new 40-slice SOMATOM Sensation Open system, and the high-capacity patient table, will start in July 2005.
