本文介绍了回波容积成像（EVI）技术的改进及其在全身研究中的应用。使用自制的0.5 T回波平面成像系统，在102 ms内采集完整的模数三维图像数据，并实时显示。硬件限制已将可实现的最大阵列大小限制为64 x 32 x 8体素。代表性的体素尺寸为x = 6.0 mm; y = 4.0 mm，z = 10.0 mm。给出了人类志愿者的结果，显示了心脏、肝脏和膀胱图像。还示出了第一EVI胃充盈和排空结果。
Improvements 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 x 32 x 8 voxels. Representative voxel dimensions are x = 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 emptying results.
