Planning study of flattening filter free beams for volumetric modulated arc therapy in squamous cell carcinoma of the scalp. [PDF]

PLoS ONE, 2014
Flattening filter free (FFF) beams show the potential for a higher dose rate and lower peripheral dose. We investigated the planning study of FFF beams with their role for volumetric modulated arc therapy (VMAT) in squamous cell carcinoma of the scalp ...

Dosimetric Comparison between High Dose Rate Brachytherapy Boost and Volumetric Arc Therapy Boost in Locally Advanced Cancer Cervix

Asian Journal of Oncology, 2021
Concurrent chemoradiotherapy is considered the standard treatment for the locally advanced cancer cervix (LACC). Radiotherapy is commonly administered by a three-dimensional conformal radiotherapy (3DCRT) approach followed by brachytherapy (BT).

Dosimetric Comparison of Hypofractionated Regimen in Breast Cancer Using Two Different Techniques: Intensity-Modulated Radiation Therapy (IMRT) and Volumetric-Modulated Arc Therapy (VMAT)

Cureus, 2023
Introduction: Breast cancer treated with adjuvant hypofractionation radiotherapy with two different techniques, i.e., volumetric-modulated arc therapy (VMAT) and intensity-modulated radiation therapy (IMRT) and their effects in terms of loco-regional ...

The Spinning Manny Indexed Overlay System for VMAT total body irradiation. [PDF]

J Appl Clin Med Phys
Abstract Purpose While modern intensity‐modulated techniques for total body irradiation (TBI) offer superior organ sparing and improved dose coverage compared to conventional TBI, their complexity has limited widespread adoption. Specifically, when treating individuals with Volumetric Modulated Arc Therapy (VMAT‐TBI), a transition between the head ...

A Dosimetric Study Comparing 3D-CRT vs. IMRT vs. VMAT in Left-Sided Breast Cancer Patients After Mastectomy at a Tertiary Care Centre in Eastern India

Cureus, 2022
Introduction Post-mastectomy radiation in left-sided breast cancer in women continues to pose a significant risk to the underlying lungs and heart. This study analyzed the difference in planning target volume (PTV) coverage and dose to the organs at risk
