METHOD FOR HIGH RESOLUTION MAGNETIC RESONANCE ANALYSIS USING MAGIC ANGLE TECHNIQUE

摘要

A method of performing a magnetic resonance analysis of a biological object, i.e. an object that includes cellular matter, that includes placing the object in a main magnetic field (that has a static field direction) and in a radio frequency field; rotating the object at a frequency of less than about 100 Hz around an axis positioned at an angle of about 54 DEG 44' relative to the main magnetic static field direction; pulsing the radio frequency to provide a sequence that includes a magic angle turning pulse segment; and collecting data generated by the pulsed radio frequency. The object may be reoriented about the magic angle axis between three predetermined positions that are related to each other by 120 DEG . The main magnetic field may be rotated mechanically or electronically. Methods for magnetic resonance imaging of the object are also described.
