August 28, 2009 - More than 40 presentations at the 10th Biennial ESTRO Conference on Physics and Radiation Technology for Clinical Radiotherapy that explore use of the TomoTherapy treatment system.
The TomoTherapy system – a CT scanner-based device that integrates image guidance and helical radiation therapy delivery for enhanced tumor targeting – is used in cancer centers around the world. The papers cover a breadth of advantages related to the TomoTherapy system, including the importance of daily imaging for precise patient positioning and adaptive therapy purposes, fundamental advancements in treatment planning and improvements in treatment quality for the patient.
The ESTRO Conference will take place August 30 to September 3, 2009, in Maastricht, The Netherlands.
At booth 140, TomoTherapy will highlight how its radiotherapy platform is reshaping radiation therapy, with exhibits and presentations on topics such as the evolution and future of the TomoTherapy platform, user case studies, use of TomoDirect technology to increase system versatility and throughput, and the new TQA™ quality assurance tool.
The conference will feature more than multipl TomoTherapy-related papers, on a range of topics, including:
Clinically Applied Imaging
Adaptive Radiotherapy to Treatment Response – UCL-Cliniques Universitaires Saint Luc, Brussels, Belgium. This study explores how recent advancements in imaging, computational and technological fields may enable clinicians to achieve high precision radiation dose delivery. Initial results show that use of the TomoTherapy system’s adaptive planning capabilities allows for a significant reduction in the volume of tissue irradiated to high dose and may assist in responding to dosimetric variations caused by anatomical changes during treatment, providing the opportunity to employ dose escalation strategies.
Evaluation of Megavolt CT (MVCT) Imaging Protocols in the Treatment of Head and Neck Cancer with Helical TomoTherapy – ZNA Middelheim-UZA, Antwerp, Belgium. This study was designed to evaluate several imaging protocols based on the results of an extended evaluation of TomoTherapy MVCT images, acquired on a daily basis, for head and neck cancer patients. Researchers concluded that the TomoTherapy system enables quick and easy daily imaging and reduces margins that account for set-up uncertainties, which therefore reduces the amount of healthy tissue that is irradiated during treatment.
Validation of an Elastic Registration Method to Parotid Shrinkage as Assessed by MVCT Scans during TomoTherapy –Scientific Institute San Raffaele, Milan, Italy; IBFM-CNR and Scientific Institute San Raffaele, Milan, Italy; and IBNM-CNR and Politecnico, Milan, Italy. This paper evaluated the use of MVCT images during TomoTherapySM treatments to address changes in the parotid gland as a way to reduce common side effects of radiotherapy during treatment of head and neck cancer. The study concludes that daily MVCT scans enabled clinicians to evaluate the three-dimensional behavior of tissues during the course of radiotherapy, with a detailed analysis of position, volume and shape, and calculate an accurate dose received by the parotids during the course of treatment.
