Stereotactic radiation therapy immobilizer RPS Head

stereotactic radiosurgerySRTSRS

Overview
The RPS Head is a retrofit angular correction add-on designed for precise patient alignment in head & neck radiotherapy and cranial stereotactic radiosurgery (SRS). It provides manual 6DoF adjustments (pitch, roll, yaw) with sub-degree angular accuracy and submillimeter positional reproducibility, enabling integration with surface‑guided radiotherapy (SGRT) workflows without removing thermoplastic masks or interrupting the treatment sequence.

Key Features

• Manual 6DoF angular correction at the treatment table (pitch, roll, yaw)
• Sub-degree angular accuracy and submillimeter positional reproducibility
• Compatibility with single- and two-piece thermoplastic mask systems and standard indexing boards
• Retrofit-ready design for installation on existing indexing plates
• Supports SGRT-based workflows for surface tracking and alignment

Product Highlights

• Model: RPS Head (angular correction add-on)
• Mass: 4 kg
• Angular correction range: ±4° per rotational axis (clinical range; mechanical limits depend on configuration)
• Patient weight capacity: up to 200 kg
• Mask compatibility: supports 5+ mask types (examples: Orfit, Qfix, CQ Medical, 3C, IT‑V, Macromedics)

Advantages and clinical benefits
The RPS Head enables controlled angular corrections after mask fixation, preserving mask-based immobilization while improving beam alignment and reproducibility across fractions. This reduces the need for additional imaging and supports improved dose conformity in stereotactic and fractionated treatments.

• Improved beam alignment through sub-degree angular correction
• Maintains reproducible geometry across treatment fractions
• Facilitates SGRT-guided setup verification and correction
• Retrofit integration minimizes disruption to existing clinical hardware

How you benefit
Provides cost‑efficient, manual 6DoF alignment for ring-mounted and helical platforms (e.g., Halcyon®, TomoTherapy®) and conventional photon systems. The plug‑and‑play retrofit approach streamlines clinical adoption and preserves current mask workflows while improving targeting accuracy and treatment reproducibility.

Applications

• Stereotactic radiotherapy (SRT / SRS)
• Surface‑guided radiotherapy (SGRT) workflows
• TomoTherapy® and other ring/helical photon platforms
• Head & neck radiotherapy with thermoplastic masks
• Fractionated brain radiotherapy and metastasis treatments

FAQ / Technical notes

• The RPS Head uses a precision 6DoF mechanism to permit fine angular adjustments after mask fixation, enabling submillimeter and sub-degree corrections without mask removal.
• System-independence: compatible with common mask systems and standard indexing boards; many setups require no additional adapters.
• Angular correction per axis: clinically relevant ±4° range with sub-degree accuracy; see technical datasheet for exact mechanical limits by configuration.
• Designed and manufactured under ISO 13485 processes; MDR-compliant and FDA cleared where applicable.
