The PerfectPitch™ therapy table with 6 degrees of freedom

PerfectPitch™ 6 degrees of freedom couch

Technical solutions


Varian designs the PerfectPitch 6 degrees of freedom couch for state-of-the-art, high-dose radiotherapy techniques where precise patient positioning is critical:

• Intensity Modulated Radiation Therapy (IMRT)
• Stereotactic Radiosurgery (SRS)
• Stereotactic body radiotherapy (SBRT)

A robotic couch with 6 degrees of freedom, used in conjunction with the imaging of the  TrueBeam® radiotherapy system, avoids patients positioning mistakes and improves target placement. In addition, two extra axes of rotation, pitch, and bank are available - the couch is continuously adjustable in six axes, providing isocentric displacement.

Steps that can be performed from the control room:

CBCT imaging targeting
isocenter position correction
treatment review
treatment delivery
axis registration


• Improved accuracy for the most complex cases
• Robotic positioning
• Isocentric rotation
• Fully integrated with Edge® radiosurgery system and optionally with TrueBeam
• Sub-millimeter accuracy
• Load capacity up to 200 kg
• Remote positioning based on images

Thanks for the application!
