Biomedical Prospects for Ultrasound Holography

摘要: The basic problems associated with ultrasonic imaging by holographic methods are presented and the implications relative to possible diagnostic application discussed. Several techniques for recording magnitude phase of sonic fields analyzed recent results obtained a mechanical scanning system presented. distortion aberration reconstructed images which wavelength scaling present technological obstacle be overcome. nature image presentation that has been used in reconstruction visible neither entire information contained hologram nor achieved desirable geometry. An intermediate processing scheme may provide useful approach toward solution these problems. propagation ultrasound biologic tissue resulting an field emanating from such subject have yet fully understood or analyzed. There is little doubt, however, given suitably rapid detection system, very considerable can this method.
