摘要:
AbstractImprovements in the echo‐volumar imaging (EVI) technique and its application in whole‐body studies are described. Using an in‐house built 0.5 T echo‐planar imaging system, complete modulus three‐dimensional image data are acquired in 102 ms with real‐time display. Hardware limitations have restricted the maximum array size achievable to 64 × 32 × 8 voxels. Representative voxel dimensions areX= 6.0 mm;y= 4.0 mm, and z = 10.0 mm. Results on human volunteers are presented, showing cardiac, liver, and bladder images. Also shown are the first EVI gastric filling and emp
