About

Chih-Ju Chang is a leading researcher in the field of surgical robotics and medical image-guided interventions, with a primary focus on developing intelligent assistive systems for minimally invasive procedures. Her work spans three critical domains: robotic high-intensity focused ultrasound (HIFU) ablation for noninvasive tumor treatment, computer-assisted orthopedic surgery, and advanced spinal navigation. Dr. Chang’s most impactful contribution is the development of an ultrasound imaging-guided robotic HIFU system, which integrates real-time imaging with precise robotic control to enable noninvasive thermal ablation of tumors—a technology with high potential for transforming cancer therapy (15 citations). She has also engineered a drilling assistive device that dramatically reduces the need for intraoperative X-rays during intramedullary nailing for long bone fractures (10 citations), and has pioneered the clinical evaluation of the i-Navi 2D C-arm robotic navigation system for spine surgery (7 citations). Her work on the Zeego and Brainlab navigation system in hybrid operating rooms has demonstrated improved accuracy and safety for pedicle screw placement while minimizing radiation exposure to surgical staff. Through these innovations, Dr. Chang is advancing the frontier of precision surgery, making complex procedures safer, less invasive, and more accessible.
