Investigation of a source model for a new electronic brachytherapy tandem by film measurement

Abstract: PurposeTo investigate the accuracy of a vendor‐supplied source model for a new Xoft Axxent 0‐degree titanium tandem by film measurement.MethodsWe measured the anisotropy factors at varying distances and angles from the tandem in water using radiochromic film (Gafchromic EBT3) and an Epson Perfection v750 desktop flatbed scanner (US Epson, Long Beach, CA). A 0‐degree tandem was placed vertically in a water phantom. Four pieces of film, each at varying depths, were positioned orthogonal to the longitudinal axis … Show more

“…External beam RT (EBRT) usually imposes a considerable amount of radiation to healthy organs increasing the complications after RT in the organ at risks (OAR) along with the risk of secondary cancers [3]. In addition to the new approaches in EBRT like intensity modulated RT [4], there is a good and easily available opportunity in delivering the dose more wisely and precisely to the cancer tissue by means of brachytherapy [5], especially for prostate, cervix, and vaginal cases [6]. Due to the low time duration of treatments, High Dose Rate (HDR) brachytherapy with dose rates more than 12 Gy per hour has become more common recently for treating patients [7].…”
