EXCELART MRI system with revolutionary level of noise reduction

摘要

A magnetic resonance imaging (MRI) system is a medical imaging diagnostic device that noninvasively provides high diagnostic capability without subjecting the patient to the damaging effects of radiation. A disadvantage of such systems has beenthat the noise during scanning is uncomfortable and possibly distressing to the patient. Furthermore, many fast imaging techniques have been developed recently in order to shorten the acquisition time, but this increase in speed tends to be accompanied by an even greater amount of noise.This was the motivation for Toshiba to develop Pianissimo{sub}(tm) noise-elimination technology to drastically reduce the noise level during scanning. The application of this technology has made possible the development of a 1.5 T MRI system calledEXCELART{sub}(tm), which simultaneously achieves the previously incompatible goals of fast imaging and noise reduction.
