[Radiation dose to patients and informativeness of the images obtained during eye examinations using x-ray computed tomography].
Reducing the scanning time and the X-ray tube anode current to 80-100 mA is the main way of reducing the radiation dose without noticeably lowering the tomogram image quality in examination of the eye area using the USA QUAD-1 X-ray computer tomograph of the fourth generation. The optimum tube voltage is 140 kW. Narrowing the collimator slit and reducing the number of sections can also lower the total radiation dose, but these measures are less universal for they are determined by clinical situation.
