San adopts advanced G-Arm imaging technology

Last month, the San became the first hospital in New South Wales, and just the second nationally, to adopt new advanced G-Arm imaging technology. The technology was used for the first time at the San during a surgery performed by Head of Neurosurgery, ClinProf. Brian Owler.

The G-Arm replaces one of the hospital’s ageing O-Arm imaging systems and is fully integrated with the existing ExcelsiusGPS robotic navigation ecosystem. Compared with the previous system, the G-Arm has a smaller footprint, is easier to position and significantly improves workflow in theatre. These improvements address long-standing challenges by reducing procedure times and radiation exposure for patients and staff.

With the support of radiographers, the G-Arm provides high-quality, real-time 3D visualisation during surgery, enhancing surgical accuracy and supporting safer, more precise procedures. Its streamlined setup reduces the need for repeated equipment repositioning, helping to shorten procedure times by an average of 30 minutes per case and minimising delays caused by competing imaging demands in theatre.

The G-Arm is a versatile system that can also be applied to other specialities including for complex fracture management in orthopaedics, and tumour localisation and resection guidance in oncology. Its advanced imaging capabilities enable surgeons to safely undertake more complex procedures, while also providing a strong platform for training and education, helping to support the next generation of surgeons.

This investment reflects the San’s ongoing commitment to exceptional care and positions us at the forefront of surgical innovation.
