Navigation System Advances Image-Guided Precision Surgery

A novel on-the-fly navigation system supports advanced surgical procedures involving thoracic, abdominal, and pelvic soft-organs.

The IQQA-Guide system is a precision three dimensional (3D) imaging analytics platform designed for abdominal biopsy, minimally invasive interventional procedures, and general surgery procedures. The system uses sophisticated registration algorithms and state-of-the-art electromagnetic tracking to provide fully quantified, patient-specific anatomic models that serve to provide surgical guidance and real-time tracking and referencing to anatomic features of interest.


The models are derived from multimodality images, intended to support physicians in “seeing through” organ surfaces and quantitatively reference the anatomy during surgery. Physicians can thus locate, assess, and adjust the position of instruments relative to the full patient-specific anatomy of lesion, vessels, organs and segments, helping to reduce the need for additional intraoperative computerized tomography (CT) scans. The IQQA-Guide system is a product of EDDA Technology (Princeton, NJ, USA), and has been approved by the US Food and Drug Administration (FDA).

“The IQQA Platform now covers preoperative planning, intraoperative navigation and monitoring, and postoperative assessment to complete the full cycle of imaging-guided precision treatment,” said Jianzhong Qian, PhD, President and CEO of EDDA Technology. “Powered by our precision 3D capabilities, IQQA-Guide may help facilitate the next generation of minimally invasive and robotic treatments in precision medicine.”

The IQQA-Guide system is based on the IQQA platform, which provides fully quantitative real-time interactive and personalized solutions for advanced clinical applications including 3D quantitative analysis and visualization, automated volumetric organ/lesion segmentation and quantification, pre- and postoperative assessment, virtual planning & treatment simulation, intraoperative multimodality image guidance, and computer aided detection.
