Objective: To analyze whether deep inspiratory breath hold (DIBH) would be dosimetrically beneficial irrespective of radiotherapy planning techniques for patients with left breast cancers requiring adjuvant radiotherapy. Methods: Planning CT scans were taken in free-breathing (FB) as well as deep-inspiration breath hold (DIBH) for patients requi...

Introduction: The anatomy of the chest wall is curved which makes it quite complicated to plan radiation therapy for breast cancer. There are different techniques for delivering external beam radiation therapy. Therefore, it is essential to know the technique by which we can render a better treatment. Aim: To compare and analyse three different pla...

Objectives: To document the dose received by brachial plexus (BP) in patients treated with intensity-modulated radiotherapy (IMRT) for head-and-neck squamous cell carcinoma (HNSCC) and report the incidence of brachial plexopathy. Methods: Newly diagnosed patients of HNSCC treated with radical or adjuvant IMRT were included in this retrospective stu...

The three dimensional conformal radiotherapy (3DCRT) is developed to give good dose conformity to the target volume. The dose distributions in 3DCRT can be quantified using dose volume histograms which graphically summaries 3D dose distribution data in a single curve for each structure. With the availability of treatment planning systems various pl...
