Objective: Autologous osteochondral cartilage repair is a valuable reconstruction option for cartilage defects, but the accuracy to harvest and deliver osteochondral grafts remains problematic. We investigated whether image-guided methods (optically guided and template guided) can improve the outcome of these procedures. Design: Fifteen sheep were operated to create traumatic chondral injuries ...

Image-guided tumor ablation for lung malignancies has emerged as a treatment modality for medically inoperable patients. Overall, image-guided lung tumor ablation is a minimally invasive procedure that has an acceptable safety profile and less impact on lung function. This is important for patients with poor pulmonary and/or cardiac functions or with multiple comorbidities, which prevent them f...

A novel method for intra-operative data acquisition using a laser range scanner is presented for applications in model-updated image-guided surgery. The scanner produces a point cloud containing true-color encoded range data of its field-of-view. This allows characterization of intra-operative conditions using both intensity and geometry information. Furthermore, a rigid-body registration algor...
