A dose verification method for high-dose-rate brachytherapy treatment plans

A 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 ...

A 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...

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...

Fractionated High-Dose-Rate Brachytherapy

Purpose: A growing body of data suggests that local control in nasopharyngeal cancer (NPC) is related to the radiation dose administered. We conducted a singleinstitution study of high-dose radiotherapy (RT), which incorporated high-dose-rate (HDR) brachytherapy (BT). These results were analyzed together with data obtained from controls who did not receive BT. Patients and Methods: The BT group...
