▼a Fluoroscopically-guided neuro-interventional procedures are increasingly used in the treatment of various vascular lesions. They provide important benefits to public health, but the use of ionizing radiation usually require a long time and patie |

▼a We have successfully produced a library of lens dose values based on a series of Monte Carlo simulation to quickly determine the lens dose for a given set of conditions. Also, organ and effective dose for long interventional procedures can be ro |

▼a To evaluate the effect of patient head size on radiation dose to radiosensitive organs, such as the eye lens, brain and spinal cord, X-ray projections from different angles, CBCT scans, and neuro-interventional procedures were simulated on a com |

▼a Several patient dose reduction techniques were developed and the effect of them were also evaluated. To reduce the dose to the patient while maintaining visualization of the entire field of view, a Cu attenuator with a circular aperture for the |
