On-Board Imager – Flexibility in tumor targeting

The Varian® On-Board Imager® (OBI), makes Dynamic Targeting image-guided radiation therapy (IGRT) more efficient and convenient.

Whether clinicians want to image the patient daily or weekly, the Varian OBI provides flexible imaging protocols that meet every need.

The OBI kV imaging system delivers improved tumor targeting using high resolution, low dose digital imaging in the treatment room. Users can confidently manage patients and target movement—both before and during treatments. A choice of imaging modalities is available on the system, including 2D radiographic, fluoroscopic, or 3D cone-beam CT imaging. The use of kV imaging can result in lower patient dose and better image quality than megavoltage imaging.

Clinicians need the best possible image information to make fast accurate decisions when comparing reference images to set-up images prior to treatment. This information is the basis for key decision making: whether to continue treatment as is or change course.
