Why Motion Control Matters in Surface-Guided Radiotherapy

Accurate, markerless motion tracking defines success in frameless stereotactic and adaptive radiotherapy. Even subtle patient movement during treatment can alter dose accuracy or require reimaging. The following challenges show why advanced motion management is essential for consistent outcomes.

Undetected Intrafraction Motion

Without real-time surface tracking, minor shifts during irradiation can cause dose deviation and target miss in sensitive treatment regions.

Invasive or Outdated Tracking Methods

Tattoo-based or fiducial tracking introduces patient discomfort and delays setup. SGRT eliminates these limitations through non-invasive optical monitoring.

Lack of Integration with Positioning Systems

Many surface tracking systems operate separately from patient tables, reducing correction speed and clinical efficiency.

Workflow Interruptions During Verification

Conventional verification requires imaging pauses or repositioning, increasing treatment time and cumulative exposure.

Advantages and Benefits

The RPS SGRT enhances stereotactic and image-guided workflows by combining real-time surface tracking with integrated 6DoF motion correction. It ensures safe, reproducible, and fully non-invasive patient positioning for frameless radiotherapy.

How You Benefit

Real-time motion management

Continuously monitors and corrects patient positioning throughout the entire radiation session using an interface to surface-guided tracking - no need for invasive markers.

Higher precision in stereotactic radiotherapy

Enhances reproducibility and dose accuracy for hypofractionated treatments, reducing cumulative positioning errors and improving clinical outcomes.

Gain precision with 6DoF

Thanks to the smart connecting plate of the RPS SGRT, your existing immobilization devices and indexing systems remain fully compatible. This enables seamless integration of surface-guided workflows with submillimeter positioning precision - without replacing your accessory setup.

    Frequently Asked Questions

    What specific clinical workflows and treatment types benefit most from the RPS SGRT motion management system?
    The RPS SGRT is specifically engineered for frameless stereotactic, adaptive, and hypofractionated radiotherapy workflows where precise intrafraction motion management is critical. By continuously tracking patient anatomy without invasive markers or tattoos, it prevents undetected shifts during irradiation that could cause dose deviations or target misses. The platform ensures exceptional targeting accuracy and reproducibility across all fractionated sessions, making it highly valuable for motion-sensitive treatment regions. Its real-time correction capabilities eliminate the need for imaging pauses or workflow interruptions, optimizing overall clinical efficiency and dose accuracy.
    Unlike isolated positioning systems, the RPS SGRT features an open API architecture designed for deep integration with LINAC and SGRT OEM platforms. It is highly adjustable and fully compatible with all major optical surface tracking scanners on the market to enable real-time, synchronized data exchange. This open control interface allows system developers to link live surface tracking data directly to the table’s 6DoF motion logic for immediate intrafractional corrections. Consequently, OEMs can bundle this couch into diverse, multi-vendor configurations without experiencing software or communication bottlenecks.
    The RPS SGRT platform delivers exceptional submillimeter positioning precision with a verified accuracy of 0.2 mm. To correct rotational and translational deviations instantly during the radiation session, it provides a +/-5° angular correction range across all axes. Structurally, the robust mechanical design easily supports a high patient weight capacity of up to 200 kg while maintaining maximum stability. Furthermore, it offers three distinct board options to perfectly accommodate various modular OEM setups and specific treatment environments.
    Yes, the RPS SGRT features a smart connecting plate that ensures full mechanical compatibility with industry-standard indexing systems and carbon baseplates. This allows clinics and OEMs to seamlessly adopt surface-guided workflows without replacing their entire legacy inventory of thermoplastic masks or vacuum bags. By supporting existing immobilization hardware from leading brands, it minimizes transition costs and reduces cumulative positioning errors. It effectively combines non-invasive optical monitoring with your established clinical accessory ecosystem for enhanced workflow precision.
    The RPS SGRT provides continuous markerless motion tracking and real time position correction throughout the entire radiation session. By interfacing directly with optical surface scanners, the platform immediately detects subtle patient shifts that could cause dose deviations or target misses. The integrated 6DoF mechanism then executes submillimeter adjustments to maintain perfect isocenter alignment without interrupting the clinical workflow. This non-invasive motion management drastically enhances targeting accuracy and patient safety during highly sensitive frameless stereotactic therapies.
