Some investigation has been made in recent years of radiation dose to the eye during radiological procedures. A comparative survey has been made of eye dose during petrous bone tomography in different departments on different tomographic units and during different types of examination. Doses of up to 4 rad per exposure have been recorded and various methods of reducing the dose have been investigated, the most successful being the use of 1 mm lead eyeshields or examining the patient in the posteroanterior position.
近年来，已经对放射学检查过程中眼睛所受的辐射剂量进行了一些研究。针对不同科室、不同断层扫描设备以及不同类型检查的岩骨断层扫描期间的眼部剂量进行了一项比较调查。记录到每次照射的剂量高达4拉德，并且已经研究了各种降低剂量的方法，其中最成功的方法是使用1毫米铅制眼罩或采用后前位对患者进行检查。
