MAGNETIC RESONANCE IMAGING METHOD FOR HEART USING MULTIPLE SLABS AND MULTIPLE WINDOWS

摘要

PROBLEM TO BE SOLVED: To enable to obtain a 3D MRI data collection in a short time by setting multiple respiration gate windows, performing a pilot scanning defining corresponding multiple slabs, and combining the obtained 3D MRI data to form a single 3D MRI data collection indicating an interesting area. SOLUTION: This system is controlled by an operator console 100 connected to a computer 107 via a link 116, and the computer 107 is connected to a system control part 122 containing a pulse generation module 121 via a high-speed serial link 115. To obtain a 3D MRI data collection, multiple respiration gate windows (hereinafter, designated as G.W) are set, and a 3D interesting area is divided into multiple 3D slabs corresponding to multiple G.Ws. When detected respiration points are in the range of multiple windows of the G.Ws, a MRI data is obtained from the corresponding 3D slabs.
