Abstract

Clinical observations revealed that duplication artifacts in B-mode-ultrasound depend on rib cartilage in the sound field. The in-vivo conditions were imitated by watertank experiments with an acrylic glass magnifier which has the properties of an acoustic dispersing lens. With this the duplication artifacts proved to be caused by acoustic dispersing lenses, in-vivo due to rib cartilage, for example.

摘要

临床观察发现，B 型超声中的重复伪像取决于声场中的肋软骨。通过使用具有声散射透镜特性的丙烯酸玻璃放大镜进行水槽实验来模拟体内条件。由此证明，重复伪像例如在体内是由声散射透镜引起的，是由于肋软骨造成的。
