CNERGY Total Body Irradiation (TBI)

Total Body Irradiation (TBI) can be a complex treatment and may take up to an hour. Patient movements or positioning difficulties can double the time required. That is why the CNERGY TBI  can help you significantly improve Total Body Irradiation treatment setup procedures and outcomes. This mobile stand-alone imager is part of the integrated CNERGY product suite and the only commercially available TBI product of its kind today. Instead of simply producing a single image, the solution relies on Intrafraction Monitoring in the form of live video capture to provide high-quality megavoltage (MV) images. Video captures can be stopped and restarted to accommodate for changes in the patient’s position – so there’s no risk of needing to repeat the entire patient setup procedure. This will deliver significantly greater efficiency, faster results and improved treatment quality.¹

Key features:

  • Verification with (sub)-millimeter precision2
  • Real-time (intrafraction) monitoring during entire total body irradiation treatment
  • Large TBI imaging area of 75 x 46 cm
  • Dicom RT support to import treatment plan information to use as reference
  • Clinical audio alarm when difference in color coded image exceeds predefined treshold


  • Improved patient setup¹
  • Reduce overall total body irradiation treatment times¹
  • Patient setup verification software specially designed for TBI workflow
  • Patient position is continuously monitored
  • Mobile unit

CNERGY Total Body Irradiation: Focus on accuracy, efficiency and safety

During treatment, you need to ensure your patient is positioned correctly and that the dose given is in line with the treatment plan. CNERGY setup verification software helps to automatically set up and correct the positioning of a patient or compensator/ blocker. Matching tools constantly monitor patient anatomy for movement readouts with sub-millimeter precision.2

Throughout the entire total body irradiation treatment process, Intrafraction Monitoring is active and a live video feed is provided. Images are acquired every second during treatment to verify patient position and compensator/blocker position. A color-coded image shows differences between the patient’s current position and the position at the outset. This comparison is supported by a clinical audio alarm, audible whenever the difference exceeds a predefined threshold. Treatment can be manually stopped and continued, based on real-time (software) feedback.
