Background and purpose: Dose calculations in trachea HDR brachytherapy treatment planning systems are greatly based on TG-43 protocol in which, all materials including air inside trachea are treated the same as water. The aim of this study was to survey the effect of air on dose calculations of Flexiplan treatment planning system in trachea HDR brachytherapy. Materials and methods: To ev...
Introduction: Brachytherapy is one type of internal radiation therapy where radiation sources, which are usually encapsulated, are placed as close as possible to the tumor site or inside the patient's body. In this technique, it is important to determine dose distribution around the brachytherapy capsule to create optimal treatment plant. In this way, dosimetric parameters are...
Gynecological care is vital to women's health but utilization of gynecological care has been seldom addressed. We applied the population-based "ecology model" to demonstrate the utilization of gynecological care of women, with examples from Taiwan. We analyzed the claims data from the cohort datasets within the National Health Insurance Research Database in Taiwan. Women's utilization of gyneco...
Traditional brachytherapy refers to the placement of radioactive sources on or inside the cancer tissues. Based on the type of sources, brachytherapy can be classified as radionuclide and electronic brachytherapy. Electronic brachytherapy uses miniaturized X-ray sources instead of radionuclides to deliver high doses of radiation. The advantages of electronic brachytherapy include low dose to or...
This investigation studies the use of volumetric-modulated arc therapy (VMAT) to deliver the following conceptual gynecological brachytherapy (BT) dose distributions: Type 1, traditional pear-shaped dose distribution with substantial dose gradients; Type 2, homogeneous dose distribution throughout PTV (BT prescription volume); and Type 3, increased dose to PTV without organ-at-risk (OAR) overdo...
The theme of the conference was " Brachytherapy – an Immortal Art ". The pre-conference workshop (26 th August 2016) was conducted at Cancer Institute (WIA), Adyar, Chennai. The workshop included live hands-on demonstration of interstitial brachyther-apy procedures for oropharyngeal cancer (base of tongue), and intra-operative brachytherapy for soft tissue sarcoma of gluteal region. The procedu...
