Clinical implementation of DIBH benefits patients

AccuTrak clinical application Advantage

• Advantages at CT Simulation Side:

  Real-time Feedback for Breath-hold Monitoring: Provides immediate visual guidance during CT simulation, enabling precise definition of the respiratory baseline and accurate setting of the gating window. Effective Respiratory Coaching & Patient Selection: Facilitates structured breathing training prior to simulation, ensuring patient compliance and the ability to reproduce a stable, coached breath-hold. This helps screen out patients unsuitable for breath-hold techniques, preventing uncoordinated ("blind") breath-holds. Enhanced Reproducibility: Establishes a patient-specific, quantifiable breath-hold baseline during CT scanning, forming the critical reference for subsequent treatment.
• Advantages at treatment Side:

  Automated Synchronization & Beam Gating: Automatically synchronizes with the pre-defined respiratory baseline and gating window established from CT simulation. This enables real-time beam gating or triggering, ensuring radiation delivery only occurs when the patient's breath-hold position precisely matches the planned position. High-Precision Reproducibility: Allows patients to accurately replicate their coached breath-hold state achieved during simulation, significantly reducing intra-fractional motion uncertainties and enhancing targeting accuracy. Non-invasive, Continuous Monitoring: Offers frameless, continuous surface tracking without additional ionizing radiation exposure, improving patient comfort and workflow efficiency throughout treatment.
• Expanded Workflow Integration & Clinical Impact:

  Seamless Data Continuity: Creates a closed-loop feedback system from simulation to treatment. The respiratory pattern and gating parameters defined during CT simulation are seamlessly transferred to the linac, ensuring a consistent and standardized approach. Proactive Quality Assurance: By identifying patients who cannot consistently reproduce the breath-hold during the CT session, potential treatment inaccuracies are mitigated proactively, optimizing resource allocation and patient safety. Adaptive Therapy Potential: The continuous surface data stream can be logged and analyzed for each fraction, providing valuable information for adaptive therapy strategies and treatment response assessment related to anatomical changes
