Philips Healthcare has placed the first Achieva 3.0T TX magnetic resonance imaging (MRI) system into several hospitals around the world. The scanner, featuring Philips' MultiTransmit technology that automatically adjusts the RF signal to a specific patient's anatomy, has recently been installed at Tokai University in Tokyo, Japan, Bonn University in Bonn, Germany and Fletcher Allen in Burlington, Vermont. These sites will utilize the Achieva 3.0T TX for procedures including breast MR, spine imaging and abdominal cases.

"MultiTransmit enables 3T MRI spine exams to be done approximately 30-40 percent faster," said Dr. W.A. Willinek, Bonn University Hospital. "MultiTransmit technology provides consistent results in all anatomies since challenges of imaging at high field are now addressed at the source. Even in patients with ascites, MultiTransmit provides us with excellent signal uniformity."

Unveiled at RSNA 2008, the Achieva 3.0T TX enhances image quality, provides greater scanning speed and helps ensure fewer retakes through increased image uniformity. Capturing the correct information on the first scan in a shorter amount of time delivers more convenience to the patient and increases patient throughput potential for healthcare providers. The scanner also provides consistent results across a broad range of clinical applications and patient sizes.

In the past, 3.0T imaging has been challenging for certain clinical procedures due to dielectric shading effects and local specific absorption rates (SAR). Philips' new, proprietary, MultiTransmit technology addresses these issues at the source with multiple RF transmission signals that automatically adapt to each patient's unique anatomy. As a result, the Achieva 3.0T TX delivers superb diagnostic images for even the most demanding high field applications, such as breast and liver imaging.

Additionally, Bonn University Hospital will present papers on the MultiTransmit technology at this week's International Society for Magnetic Resonance in Medicine (ISMRM) annual meeting (April 18-24, 2009).
