The Discovery IGS 730 is a laser-guided robotic interventional X-ray system. It has the mobility of a small C-arm with the power and image quality of a fixed system, enabling full patient access without having to suspend the device above the patient. Based on laser guidance, the C-arm is mounted on an advanced guided vehicle and is placed using predefined trajectories. Motion is predictable, precise and easy to use while creating sterility for a flexible and secure operating-room environment. It features one-touch back out and back in, enabling fast and easy system movement away from the patient and exact repositioning. Parking locations and back-out distances are customizable for different room configurations. Its wide-bore design allows for steep angles and ease in 3D C-arm-rotation acquisition, especially with large patients.

In the three years that the IGS 730 was developed, the design team had to tackle many challenges: make the system technically achievable and aesthetically perceptible as a premium design, be unique but consistent with other interventional guided systems, anticipate future hybrid room requirements and procedures, be adjustable to multiple room dimensions, enable fast installation and serviceability, limit collision but allow the system to move quickly, manage cables, develop controls at the advanced guided vehicle and the table side, be preventive without being invasive, keep the patient accessible, and be movable in case of power shut down. The integrated team (engineering, marketing, ergonomics and design) quickly developed a functional prototype based on worldwide observation research, vision validation and user testing following a common goal: revolutionize minimally invasive imaging.

The system combines engineering breakthroughs (laser-guided robotic system), with user empathy (by optimizing working footprint and system mass, which often stand in the way of the operator), which together form a surprisingly delightful new user experience for radiologists and surgeons. Patient stress was also reduced though reduced volume perception and by creating a calm shadow area around the patient’s head. The Discovery IGS 730 ensures that the highest quality images are captured using low X-ray dose emissions, for optimum patient safety.

The interventional market is mature and conservative, and the business decision to move forward with this product represents a bold step for GE. Design was a key driver of this concept and has enabled the interventional business to move forward in terms of market thought leadership in a truly come-from-behind manner.
