MAGNETIC RESONANCE APPARATUS AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To reduce an impact of a side lobe on a respiratory signal in belly imaging using a respiration synchronization method by a magnetic resonance apparatus.SOLUTION: Navigator sequences NS1 and NS2 set so as to satisfy |W'(K')|S'(K')=|W(K)|S(K) and θ'=-θ are performed (ST1). Navigator data is acquired from an echo collected by the navigator sequence NS1, and navigator data is acquired from an echo acquired by the navigator sequence NS2. The navigator data are added (ST2), and an edge position of the liver is detected based on the added navigator data (ST3).SELECTED DRAWING: Figure 11
