Clinical symptoms and volumetric radiological responses of acoustic neuroma patients, treated with hypo-fractionated image guided radiotherapy (IGRT) at Groote Schuur hospital between 2013 and 2016
… patients treated with fractionated stereotactic radiotherapy (SRT) using photons. We describe clinical and radiological outcomes of AN patients treated with SRT at an academic centre in Cape Town, South Africa. Objectives: To describe patient demographics, tumour characteristics and patients’ …

Image quality and dose of an accelerator-integrated kV CBCT systems
… about tumor position is critical in the radiotherapy process. As image-guided radiotherapy (IGRT) becomes more popular in radiation treatment, its overall quality and performance, such as the image quality and amount of dose delivered, need to be assessed. The research described in this …

Evaluation of Deformable Image Registration For Improved 4D Ct-Derived Ventilation For Image Guided Radiotherapy
… studies have demonstrated the use of physiologic images in radiation therapy treatment planning to identify regions for functional avoidance. This image-guided radiotherapy (IGRT) strategy may reduce the injury and/or functional loss following thoracic radiotherapy. 4D computed tomography (CT), …

Modelling geometric uncertainties in prostate radiotherapy
Image guided radiotherapy (IGRT) presents a range of techniques to enhance thegeometric accuracy of radiotherapy treatment. A full evaluation of such techniques,against increased cost, workload, or unnecessary radiation dose, would require theincorporation of geometric errors into existing methods …

Applications of cone beam computed tomography in radiotherapy treatment planning.
In recent years Image-Guided Radiotherapy (IGRT) has experienced many technical advances. One of the most significant has been the widespread implementation of kilovoltage imagers attached to the gantry of linear accelerators (LINACs); these units are capable of 2D planar imaging, fluoroscopy and …
