From Toshiba America Medical Systems Inc.;
http://www.medical.toshiba.com/clinical/radiology/vantage.htm 'With its high-field strength, the Vantage™ delivers the clinical capabilities and image quality expected by cardiologists, while simultaneously offering patients a more comfortable and non-invasive option,' said Dane Peshe, director, MRI Business Unit, Toshiba America Medical Systems. 'Vantage™ supports a full complement of cardiovascular imaging studies, ranging from stroke evaluation to peripheral vascular imaging. Additionally, the ultra short bore design offers patients a greater feeling of openness that reduces claustrophobic sensations, while Toshiba's exclusive, patented Pianissimo™ technology reduces scan noise by as much as 90 percent for a more pleasant experience.'
