title: The role of endoscopic ultrasound (EUS) in planning radiotherapy target volumes for oesophageal cancer.
abstract: Computed tomography (CT) scanning is the main imaging modality utilised for planning radical oesophageal radiotherapy. Endoscopic ultrasound allows accurate localisation and local staging of oesophageal tumours. A method of incorporating this information into the CT planning process is described. Gross tumour volume position changes that occur when using this technique are presented.
