Spin warp NMR imaging and applications to human whole-body imaging.

摘要: Describes a new nuclear magnetic resonance (NMR) imaging technique which the authors call 'spin warp imaging' and gives examples of its application to human whole-body imaging. The apparatus is based on four-coil, air cored magnet (made by Oxford Instrument Company) capable accepting whole body. produces static field 0.04 T giving proton NMR frequency 1.7 MHz. maximum inhomogeneity about 6*10-4 at radius 0.23 m, approximately twice amount theoretically attainable with this configuration. pulse sequence used shown.
