Because the part of the globe in direct contact with the transducer cannot be visualised and focussed transducers have poor imaging qualities at a distance less than 5-8 mm from their surface, diagnostic ultrasound of the anterior eye segment has been treated in a stepmotherly way. With a simplified immersion technique we can visualize quite accurately a variety of pathologic conditions of the cornea, anterior chamber, iris, lens and ciliary body. The B-mode information is superior to the A-mode in this part of the eye.
由于与换能器直接接触的眼球部分无法可视化,而且聚焦换能器在距离其表面小于5 - 8毫米时成像质量较差,眼前节的诊断超声一直未得到充分利用。通过一种简化的浸没技术,我们可以相当准确地观察到角膜、前房、虹膜、晶状体和睫状体的各种病理状况。在眼部的这一部分,B型信息优于A型信息。
