Advances in Radiation Therapy Treatment Systems

While radiation therapy as a discipline is well into maturity, new technology advances continue to drive the field forward. The following is a roundup of some of the most significant products to launch or be introduced in the last 12 months.

Image-guided radiation therapy (IGRT) offers a more precise and accurate form of treatment than standard photon radiotherapy, incorporating imaging during treatment delivery to more closely assess tumor response. One imaging modality in particular that has shown promise in this application is magnetic resonance imaging (MRI) for its ability to provide real-time anatomical and functional information without giving added radiation dose to the patient.

UF startup Viewray was the first to market with a commercial MRI-guided radiotherapy system in the U.S., earning U.S. Food and Drug Administration (FDA) approval for the MRIdian system in 2012. In February of this year, Viewray earned FDA approval for new soft tissue visualization capabilities on MRIdian, including:
