The VacFix® SBS system is a dedicated radiotherapy immobilisation system engineered to improve precision, reproducibility, and comfort during patient setup. Unlike standalone vacuum cushions, the SBS integrates a shaped support structure that stabilises the vacuum cushion in place, ensuring consistent geometry across multiple fractions of treatment and supporting consistent clinical outcomes across patient populations.
This Shape Body Support device is designed to reduce setup errors, streamline workflows, and improve patient throughput in busy radiotherapy centres. The modular design makes it suitable for a range of applications, including thoracic, abdominal, and pelvic treatments. By combining adaptability with rigid support, the SBS helps radiation therapists achieve both immobilisation accuracy and clinical efficiency while maintaining patient comfort throughout longer treatment sessions.
The VacFix® SBS has been developed to work in conjunction with the full VacFix® Cushion range, offering clinics flexibility in immobilisation strategies. Cushions can be moulded to individual patient anatomy, locked into the patient support frame, and re-used across sessions to ensure reproducibility. This integration minimises the risk of patient movement while supporting comfort, a key factor in maintaining compliance during lengthy treatment sessions.
Thoracic immobilisation – stabilises the chest for reproducible lung and mediastinum treatments
Pelvic immobilisation – secures lower body positioning to minimise rotational and translational errors
Abdominal immobilisation – supports precise setup for upper GI and liver radiotherapy
Combined use with VacFix® Cushions – creates a robust immobilisation platform adaptable to patient anatomy
The SBS system is provided as a structured support unit designed to integrate directly with VacFix® Cushions. Specific catalogue sizing for the SBS system is standardised (not as variable as the cushions), meaning it is offered in one main configuration adaptable to different cushion types.

For departments seeking to combine flexibility with reproducibility, the VacFix® SBS radiotherapy immobilisation system provides the ideal balance. It allows radiotherapy teams to use adaptable vacuum cushions while maintaining a stable, consistent setup geometry supported by a rigid patient support frame. This integration reduces inter-fraction variation, improves patient comfort, and saves valuable clinical time.
The SBS system is used worldwide as a proven Shape Body Support device, helping clinicians deliver highly accurate radiotherapy with confidence in patient safety and comfort.
