Siemens to dramatically improve Magnetic Resonance imaging using total imaging matrix technology

Malvern 25 November 2003Siemens Medical Solutions introduces a new technology that will dramatically change and improve Magnetic Resonance (MR) imaging. Total imaging matrix technology, dubbed Tim, is the first seamless, whole body surface coil design that combines 76 seamlessly integrated coil elements with up to 32 RF channels, opening the door to the most advanced clinical applications available today. MAGNETOM Avanto, the first MR system based on Tim technology, will be unveiled at the 89th Scientific Assembly and Annual Meeting of the Radiological Society of North America (RSNA), November 30 - December 5 in Chicago, Illinois.


Tim provides significantly improved work flow by virtually eliminating the need for patient repositioning and manual coil changes, while providing significantly enhanced image quality. Tim's surface coil design makes true 205 cm (6'9") whole body imaging possible in a single exam, while other systems require the radiologist to change coils and reposition the patient three times for a whole body MR imaging procedure. As a result, image quality is increased by up to 100 percent signal-to-noise ratio (SNR), and acquisition times are shortened.

"Innovation of this caliber is a trademark of Siemens", stated Dr. Erich R. Reinhardt, president and chief executive officer of Siemens Medical Solutions. "We were the first to introduce Integrated Panoramic Array (IPA) to the MR market in 1998, many years ahead of our competition. Now in 2003, we are again making a significant contribution to the medical community that only Siemens can offer."

Tim has 76 integrated coil elements, up to 32 channels (76x32), and its integrated coil weighs less than two pounds. It also features Siemens' unique integrated Parallel Acquisition Technique (iPAT), which offers fast image acquisition with parallel imaging in all dimensions, including head to toe, front to back, and side to side.

Tim allows radiologists to select exams, not coils, and provides the highest acquisition speed without image artifacts or restrictions in coverage, giving radiologists the opportunity to conduct advanced applications, such as metastasis evaluation. "Tim is to MR what multi-slice technology was to CT, so the impact on work flow and application options will really be quite substantial", stated Heinrich Kolem, president of the MR Division of Siemens Medical Solutions. "The introduction of Tim sets Siemens Medical Solutions two generations ahead in MR imaging."

The Tim Application Suite includes a comprehensive set of clinical applications, including Neuro, Angio, Cardiac, Body, Oncology, Orthopaedic, and Paediatric. These suites are optimized for Tim and contained in the basic configuration of any Tim system. The first Tim installation is currently in progress at New York University Medical Center. The facility will complete installation of the MAGNETOM Avanto later this month.

The MAGNETOM Avanto, Siemens newest high-end 1.5 Tesla MR system, incorporates Tim, the first seamless, whole body surface coil design and RF technology. The Avanto offers many advantages over other systems, such as 97 percent acoustic noise reduction, without compromising image quality. The system also provides seamless metastasis evaluation, whole CNS imaging and visualization of vascular diseases, and less stressful procedures due to shorter times and feet-first exams.

In addition, the Avanto also features work flow automation tools such as Phoenix software that allows clinicians to transfer protocol for medical images from a CD, making it possible to initiate a scan directly from the image. Clinicians always have a reference available so they can duplicate a protocol or follow a patient over time by performing an identical study without having to re-enter protocol parameters.
