High-Dose-Rate 192Ir Brachytherapy Dose Verification: A Phantom Study
BACKGROUND The high-dose-rate (HDR) brachytherapy might be an effective tool for palliation of dysphagia. Because of some concerns about adverse effects due to absorbed radiation dose, it is important to estimate absorbed dose in risky organs during this treatment. OBJECTIVES This study aimed to measure the absorbed dose in the parotid, thyroid, and submandibular gland, eye, trachea, spinal c...
متن کاملIndependent assessment of source transit time for the BEBIG SagiNova® high dose rate brachytherapy afterloader
Introduction: The dwell time and transit time components contribute to the overall delivered dose to patients in high dose rate (HDR) brachytherapy treatments. The transit time results from source entry and exit as well as source movements between dwell positions. It depends on various parameters such as the source speed profile, source indexer distance to dwell position, and ...
متن کاملMeasurement verification of dose distributions in pulsed-dose rate brachytherapy in breast cancer.
AIM The aim of the study was to verify the dose distribution optimisation method in pulsed brachytherapy. BACKGROUND The pulsed-dose rate brachytherapy is a very important method of breast tumour treatment using a standard brachytheraphy equipment. The appropriate dose distribution round an implant is an important issue in treatment planning. Advanced computer systems of treatment planning ar...
متن کاملA dwell position verification method for high dose rate brachytherapy
Misplacement of dwell positions is a potential source of misadministration in high dose rate brachytherapy. In this work we present a dwell position verification method using fluoroscopic images. A mobile C-arm fluoroscopic machine is used to take a snapshot of the treatment machine's check cable as it reaches the most distal dwell position. This fluoroscopic image is displayed side-by-side wit...
متن کاملA dose verification method for high-dose-rate brachytherapy treatment plans.
AIM To evolve a fast dose verification method for high-dose-rate (HDR) brachytherapy treatment plans and to demonstrate its applicability in different clinical cases. MATERIALS AND METHODS We developed a software tool in VC++ for the Varisource HDR unit for HDR dosimetry plan verification using TG-43 parameters. HDR treatment dosimetry of a number clinical cases using Varisource was verified ...
