数十年来,医生们为 X 光的限制所挫折。X 光能透过软组织而显露骨头和其他硬块的图象。但是,假使医生要看到软组织——腱、血管和在皮肤表面下的其他东西,不用精心细作的组织染色技术,X 光通常是无能为力的。但是,研究工作者发现,声学全息照相能够做到这一点。 For decades, doctors have been frustrated by the limitations of X-rays. X-rays reveal the image of bones and other lumps through soft tissue. However, if the doctor wants to see soft tissue - tendons, blood vessels and other things under the surface of the skin, X-rays are often powerless without elaborate tissue-staining techniques. However, researchers found that acoustical holography can do this.
