OBJECTIVE The aim of the present study was to acquire information on brachytherapy resources in Korea through a national survey of radiation oncologists. METHODS Between October 2014 and January 2015, a questionnaire on the current status of brachytherapy was distributed to all 86 radiation oncology departments in Korea. The questionnaire was divided into sections querying general information...

Brachytherapy using (198)Au grains is minimally invasive and the only curative treatment for early tongue cancer in patients of advanced age or poor performance status available in our institution. From March 1993 to February 2008, (198)Au grains were used to treat a group of 96 Stage I-II tongue cancer patients who could not undergo surgery or brachytherapy using (192)Ir pins because of an adv...

AIM The purpose of this study is to calculate radiation dose around a brachytherapy source in a water phantom for different seed locations or rotation the sources by the matrix summation method. BACKGROUND Monte Carlo based codes like MCNP are widely used for performing radiation transport calculations and dose evaluation in brachytherapy. But for complicated situations, like using more than ...

PURPOSE To investigate the use of optically stimulated luminescent dosimeters (OSLDs) for high dose rate (HDR) Ir-192 brachytherapy. While common in megavoltage radiotherapy applications, the performance of OSLDs using kilovoltage energies, high dose gradient and high dose rate regions ubiquitous to HDR has not been demonstrated. METHODS Commercially available nanoDotTM (Landauer, Glenwood, I...

Abstract The k 0 values of 6 non-1/ v nuclides ( 152 Eu, 152m 154 177 Lu, 192 Ir and 194 Ir) were determined using the extended Høgdahl formalism at research reactor FRM II with very high f values. Standards irradiated in 4 channels different local temperatures between 40 °C 55 measured temperature sensitive irreversible labels. A good agreement recommended was found for Eu Lu original g T n ) ...
