In some clinical cases respiratory motion correlates with tumor motion. The RPM Respiratory Gating System (RPM system) allows you to track respiratory motion and synchronize it with beam exposure during image acquisition and treatment delivery.

The system uses a block with reflective markers that is placed on the patient’s chest, and a camera that tracks the movement of the markers. This movement is used as a surrogate for movement of the tumor during respiration.

You can use RPM system to:

• Acquire respiratory-gated images and reference data.
• Plan a respiratory-gated radiation treatment.
• Perform pretreatment verification and deliver respiratory-gated radiation treatment.

• Respiration-synchronized treatment
  Infrared tracking camera measures respiration to help set gating thresholds.
• 3D real-time patient position monitoring
  Detecting unexpected motion offers confidence in precise treatment delivery
• Patient-friendly
  Gating system improves patient comfort and eliminates the need for breath holding
• Highly versatile
  Interfaces with On-Board Imager® kV imaging system, and PortalVision™ MV imaging systems.
• Pretreatment fluoroscopic verification of gating
  Save time and improve throughput by assessing gating thresholds before setting up patients for treatment.
• Supports all standard breathing protocols
  Expand your range of planning options, including free breathing
