gKteso - Model RPS Head -Head Enables Precise Angular Correction System for Head and Neck
The RPS Head enables precise angular correction for head and neck radiotherapy and cranial SRS. It allows submillimeter adjustments in pitch, roll, and yaw to ensure exact beam alignment and reproducible positioning. This add-on module enhances treatment precision and supports accurate surface-guided radiotherapy without interrupting workflow.
The Limits of Conventional Mask Fixation
Precise alignment is critical in cranial and head-and-neck radiotherapy. Yet even small deviations in patient positioning can significantly impact beam accuracy and treatment quality. The following challenges illustrate why immobilization alone is not enough:
Angular Deviations
Even slight misalignments in pitch, roll, or yaw can shift the radiation field and reduce dose accuracy.
Limited Adjustability
Conventional immobilization systems hold the patient securely but cannot correct angles once the thermoplastic mask is fixed.
Movement inside the mask
Conventional immobilization systems hold the patient securely but cannot correct angles once the thermoplastic mask is fixed.
Inconsistent Geometry
Without correction capabilities, geometry varies between fractions, affecting reproducibility in stereotactic and fractionated radiotherapy.
The RPS Head eliminates these limitations by allowing manual angle correction up to ±4° without removing the mask or interrupting workflow. This ensures consistent targeting, minimizes additional imaging, and maintains geometry across all fractions.
- Sub-degree correction for precise beam alignment
- Compatibility with all thermoplastic mask systems and indexing boards
- Dose conformity through reproducible geometry
- SGRT support for accurate surface-guided workflows
- Retrofit-ready design for fast integration without new hardware
Cost-efficient angular correction
RPS Head enables precise beam alignment through manual angle correction for Head and neck radiotherapy and cranial SRS, without requiring additional hardware - ideal for head and neck and stereotactic applications.
Enhance advanced systems
Augment modern ring-mounted or helical radiotherapy platforms like Halcyon® or TomoTherapy® with 6DoF alignment for reproducible treatment outcomes.
Streamline clinical workflows
RPS Head works with all standard thermoplastic mask systems and indexing boards, eliminating the need for custom integration or rework through compatibility.
Accurate imaging is crucial in stereotactic brain radiosurgery or Head & neck radiotherapy to protect healthy tissue and reduce side effects. Systems such as Varian Halcyon® deliver high precision and comfort, while the RPS Head adds direct angular correction at the treatment table for exact alignment and shorter setup times.
- Manual angle correction at the table
- Compatible with standard radiotherapy masks
- Consistent geometry for every fraction
