Title:
MAGNETIC RESONANCE IMAGING APPARATUS AND METHOD OF DECIDING EXECUTION ORDER
Document Type and Number:
WIPO Patent Application WO/2010/001747
Kind Code:
A1
Abstract:
An object is to minimize reduction in test efficiency caused by limited SAR (Specific Absorption Rate) in a test of consecutively executing a plurality of imaging sequences including different imaging sequences. In consideration of a time-dependent change in time-average SAR value in the entire test, the order of executing imaging sequences is determined to set the SAR values in a predetermined time within a predetermined range and minimize the standby time between imaging sequences. The determination is made by calculating the standby time in every conceivable execution order and selecting the minimum standby time.
