addressing interfraction movement of the bony anatomy

Elekta Synergy® PlanarView™ provides similar functionality to existing orthogonal MV portal images for initial patient set-up. However, the X-rays of PlanarView™ in the kV energy range produce high quality images at very low doses (0.2cGy).

Where MotionView™ is useful for uncertainties relating to intrafraction movement, PlanarView more specifically addresses interfraction movement of the bony anatomy.

The key visualization advantages offered by PlanarView imaging at the time of treatment include:

• quick, low-dose, snapshot images showing dense features
• lung tumors (high contrast to air)
• bony landmarks
• implanted markers in soft tissue targets
• allows for a derived 3D localization through stereoscopic (orthogonal) imaging
