“…The whole planning procedure, including needle implantation and preparation of treatment plan, was based on transrectal ultrasound (TRUS) images [8,12,16,17]. A microSelectron HDR (Nucletron B.V., Veenendaal, the Netherlands) device with iridium-192 source was used to deliver the dose [1,3,4,18]. Implantation of needles, treatment planning procedure and irradiation were carried out under extradural or general anaesthesia in the HDR treatment room [14,19].…”

“…Uniyal et al . [43] have used Gafchromic EBT2 radiochromic film and thermoluminescent dosimeters (TLD) to assess the dose rate constant and radial dose function for the Nucletron microSelectron Ir-192 source. Radiochromic film was chosen for its higher resolution compared to other experimental methods and validated against TLD results, finding agreement within 3.9% for dose rate constant and 2.8% for radial dose function.…”

This study provides a review of recent publications on the physics-aspects of dosimetric accuracy in high dose rate (HDR) brachytherapy. The discussion of accuracy is primarily concerned with uncertainties, but methods to improve dose conformation to the prescribed intended dose distribution are also noted. The main aim of the paper is to review current practical techniques and methods employed for HDR brachytherapy dosimetry. This includes work on the determination of dose rate fields around brachytherapy sources, the capability of treatment planning systems, the performance of treatment units and methods to verify dose delivery. This work highlights the determinants of accuracy in HDR dosimetry and treatment delivery and presents a selection of papers, focusing on articles from the last five years, to reflect active areas of research and development. Apart from Monte Carlo modelling of source dosimetry, there is no clear consensus on the optimum techniques to be used to assure dosimetric accuracy through all the processes involved in HDR brachytherapy treatment. With the exception of the ESTRO mailed dosimetry service, there is little dosimetric audit activity reported in the literature, when compared with external beam radiotherapy verification.

“…Recent studies evaluated the efficacy of dose measurement by radiochromic films in brachytherapy [15][16][17]. Brown et al reported the weak energy dependence of EBT3 film, which indicates that it would be a suitable dosimeter for Ir-192 radiation sources [18].…”
