TBI STEP for Total Body Irradiation
Radiotherapy
Orfit
The TBI STEP system is a rotatable tabletop designed for Volumetric Modulated Arc Therapy (VMAT) in Total Body Irradiation (TBI). It allows clinicians to overcome the limitations of standard linear accelerator couch shifts by enabling a seamless 180° rotation of the patient—from head-first supine (HFS) to feet-first supine (FFS)—within seconds and without the need for patient repositioning. The rotatable tabletop consists completely of carbon fiber, including the ball bearing within the base plate of the rotation unit. The system attaches directly to the original Linac couch top, making setup fast and straightforward. VMAT-TBI techniques typically require patients to be repositioned due to the Linac’s limited cranial-caudal couch shift range. With TBI STEP, patient rotation becomes effortless, allowing clinicians to use standard positioning devices while achieving consistent, reproducible alignment and optimal dose delivery across the full treatment volume.
Benefits
Total Body Irradiation: Achieve homogeneous dose distribution and protect healthy tissue and OARs.
Distant Metastases: Swift HFS-to-FFS rotation improves patient comfort while reducing workflow inefficiencies.
Palliative Patients: On-table rotation enhances patient comfort, optimizes workflow, and improves staff efficiency.
This rotating couch top system is designed to protect both patients and clinicians by eliminating the need for manual lifting, tilting, or physically rotating. By enabling smooth, controlled (re)positioning with minimal physical effort, the system reduces risk, safeguards staff wellbeing, and ensures patients are treated with maximum comfort and safety.
Key Benefits
Enhanced safety for everybody involved — reducing manual handling, eliminating lifting and tilting, and protecting both patients and clinical staff throughout the entire treatment process
Homogeneous dose distribution over the entire PTV using VMAT-technology
Excellent protection of healthy tissue and OARs without the use of external shields
No active participation of the patient from HFS to FFS needed
Simple rotation of the TBI STEP in a few seconds by means of hand grips
Minimization of unexpected patient movement through use of conventional positioning devices
Precise and reproducible positioning of the patient
Elimination of incorrect isocenter shifts
Avoidance of gantry-couch collision by using permitted isocentric coordinates
