dc.description.abstractBalloon dacryocystoplasty (fluoroscopically guided transluminal balloon dilatation of the lacrimal drainage system), a minimally invasive interventional radiological procedure, is a significant alternative to the surgical treatment of obstructive epiphora. The procedure, however, has a risk of radiation exposure, since radiosensitive organs such as the eyes remain in the field of the primary X-ray beam and thyroid remain in the field of secondary X-ray beam. [1-3] To properly evaluate the risk/benefit ratio of this interventional radiological treatment, accurate knowledge of the ionizing radiation dose to these organs is necessary. However, assessing the dose from fluoroscopy is difficult, primarily due to the range of many parameters (kilovoltage, milliampere, field site and size, number of exposures, and fluoroscopy time). Since the Monte Carlo Technique eliminates these instrumental parameters, it can be used for dose calculation. In this work, the radiation dose received by the thyroid at the patient suffering “obstructive epiphora” desease during diagnosis and treatment has been measured experimentally on a physical phantom and calculated theoretically by the Monte Carlo Method using a mathematical phantom. Then Tissue Skin Ratio being the ratio of the thyroid-to-entrance skin dose has been determined experimentally and theoretically and related table has been obtained. The methods used are faund to be consistant with each other.tr_TR
