42. General introduction to 3D radiotherapy

Nguyễn Hữu Nghĩa .

Nowadays, when the complexity and severity of cancer is increasing, comformal radiotherapy has proven to be one of the most effective methods to reduce the impact of cancer on patients. In my presentation, I will present to everyone an overview of 3D radiotherapy, through the main sections, such as: What is radiation therapy? 3D radiotherapy and its application cases; Steps to have a 3D...

43. Image-Guided Radiation Therapy (IGRT)

Image-Guided Radiation Therapy (IGRT) is a method that uses X-rays and images of the body to guide individual treatment. X-rays and images will show the size, shape and site of the cancer. The radiotherapy regimen wil be created to allow a high dose of radiation therapy to be delivered directly to the cancer site. The dose of radiation given to the surrounding normal tissues is kept as low as...

44. Robustness evaluation of Intensity Modulated Proton Therapy plans using Dose Volume Population Histogram

Nguyễn Thị Cẩm Thu .

Purpose: Under geometrical uncertainties, different plan evaluation methods have been suggested but the dose distribution at a specified confidence level being highly desirable is lacking. In this work, we used the DVPH (Dose Volume Population Histogram) tool to evaluate the dose distribution of CTVs and OARs (Organs at Risk) and validate the PTV concept at a certain confidence...

45. Tumor Growth Trajectory Estimation of Non-small Cell Lung Cancer Patients during Molecularly Targeted Therapy

Trương Gia Huy .

Purpose: Our study aims for investigating mathematical models to predict the tumor growth trajectories (TGTs) during the Tyrosine kinase inhibitors (TKI) therapy for the epidermal growth factor receptor (EGFR)-mutated NSCLC patients, using tumor volumes derived from CT images.
Methods: Patient data was selected by TKI treatment duration. Region of interest (ROI) segmentation then was...

46. Skin dose enhancement from the application of skin-care creams using FF and FFF photon beams in radiotherapy: A Monte Carlo phantom evaluation

Trịnh Thị Minh Anh .

07/09/2022, 12:00

Skin-care cream is commonly applied to relieve skin redness in radiotherapy. However, using cream on the patient under the photon field would increase the skin dose in delivery. The aim of this study is to evaluate the dependences of skin dose enhancement on different beam and cream variables using Monte Carlo simulation. The dose enhancement factor (DEF) defined as the ratio of the skin dose...

62. Overview of the benchmark for 3D pre-treatment QA: ArcCHECK

Lê Văn Phương .

ArcCHECK is the only true 4D array specifically designed for QA of today’s modern rotational deliveries and is recommended by AAPM Task Group 218 for 3D measurement requirements. SunCHECK™ simplifies and standardizes how hey balance it all – with full
integration and independence intact.
