摘要: Dose specification in intraluminal brachytherapy varies considerably the literature. A terminology is proposed, inspired from Paris System of interstitial brachytherapy, to define some dosimetric guidelines. The dose specified central plane which a perpendicular source and passing through its centre. reference rate calculated this plane. treated volume encompassed by isodose. hyperdose sleeve receiving equal or greater than twice dose. study distribution along linear iridium-192 was undertaken. Results obtained, also valid for caesium-137 cobalt-60, show that radius relatively independent length source. It approximately 0.6 times distance between axis point when active 3 20 cm. Reporting not only dose, but thickness tissue covered isodose included sleeve, recommended assist evaluation results treatment facilitate exchange clinical information brachytherapy. Practical examples are given.
