AlignRT Treatment For Breast Cancer

Align RT (www.visionrt.com) is a sophisticated, video-based image-guided radiation therapy (IGRT) approach which provides the ability to perform real-time tracking of the 3-dimensional (3D) surface of a patient for both setup and real-time monitoring.

The system consists of 2 ceiling mounted 3D cameras focused on the patient on the treatment table.  The cameras and a patterned light are used to reconstruct the 3D surface of the patient.

During treatment planning, a reference image is obtained with the patient in the optimal (ideal) position.  When the patient is ready to be treated, a new image is obtained each day and matched to the reference image.

Computer software compares the two images and quantitatively calculates any differences.  The Radiation Therapists then use this information to accurately re-position the patient into the optimal position for treatment.

Align RT System

The system provides continuous monitoring of the patient during treatment to ensure accurate positioning throughout the fraction. Moreover, it is a video-based system, thus patients are not exposed to additional radiation.  Patients feel nothing and may at most notice a flash or a light shining from the cameras.
