Interventional radiology surgical navigation system

ARopticalelectromagnetic

Overview
Percutaneous puncture procedures are a key subset of minimally invasive interventions used across general surgery, thoracic surgery and interventional radiology. Abdominal punctures face limitations from single-modality imaging—narrow field, lack of spatial tissue context and significant respiratory motion—making outcomes highly dependent on clinician experience. 艾瑞迈迪（Ariemedi） provides an integrated robotic solution for abdominal percutaneous procedures combining multimodal imaging and respiratory motion compensation to support ablation planning and assessment, enable precise lesion and instrument localization, and provide internal visualisation to improve procedural safety, efficiency and patient outcomes.

System modules

• Image processing: 3D reconstruction from CT/MRI; tissue and organ segmentation.
• Preoperative planning: puncture path planning; synchronized multi-needle strategies; ablation planning and prediction.
• Intraoperative navigation: real-time puncture guidance; multimodal image fusion (CT/MRI/ultrasound); respiratory motion compensation.
• Robotic arm control: motion simulation; force-sensing control; collision avoidance.

Technical advantages

• 3D reconstruction–guided path planning: reconstructs 3D tissue models at the puncture site to simulate the procedure and enable single-needle accuracy under a visualised path.
• Ultrasound-led multimodal fusion: registers ultrasound with CT/MRI to overlay precise structural information on ultrasound views, addressing localization limits of ultrasound alone.
• Respiratory motion compensation: integrates compensation into real-time intraoperative ultrasound monitoring to correct organ displacement due to breathing, improving puncture accuracy.
• Robotic arm coordination: combining precise ultrasound/CT registration with robotic control enables submillimetric operational accuracy, reducing procedural risk and improving recovery prospects.
