Radiation therapy system provider TomoTherapy is showcasing its CTrue imaging technology designed to provide image guidance for the delivery of IMRT (intensity modulated radiotherapy) at the American Society for Therapeutic Radiology and Oncology (ASTRO) meeting in Philadelphia. The technology is based on an integration of CT imaging – such as is already available as part of the company’s TomoTherapy Hi-Art System radiation therapy system. True CT imaging can be used with every patient, every day, for a range of purposes that combine to bring greater accuracy to the delivery of radiation therapy, the company said.

“CTrue technology proves that image guidance is about more than just accuracy in daily set-up,” said Thomas “Rock” Mackie, MD, TomoTherapy Inc. co-founder. “The key is what a clinician is able to do with the images acquired during the course of treatment.”

Beyond the accuracy afforded by CTrue imaging, the Hi·Art System leverages its ring gantry design for the highly-precise delivery of helical IMRT. Together, the system’s distinctive attributes are literally reshaping radiation therapy. To date, nearly 250,000 patient treatment fractions have been delivered worldwide on the TomoTherapy Hi·Art System.
