Why Immobilization Alone Is Not Enough in High-Precision Radiotherapy

In cranial and head & neck radiotherapy, achieving submillimeter accuracy requires more than reliable immobilization. While thermoplastic masks and fixation systems provide essential stability, they often reach their limits when it comes to correcting subtle angular deviations.

For OEM platforms aiming at high-precision treatment delivery, angular correction becomes a critical factor. Even small misalignments in pitch, roll, or yaw can impact dose distribution – especially in sensitive regions close to critical structures.

This is where solutions like the RPS Head close the gap. By enabling precise angular adjustments directly at the mask interface, it extends the capabilities of conventional immobilization systems without disrupting established workflows. The result is improved alignment accuracy, reduced need for repositioning, and enhanced reproducibility in daily clinical practice.

In modern radiotherapy, precision is not a single step – it’s a continuous process that combines fixation, correction, and intelligent system integration.
