Image guidance in deep brain stimulation surgery to treat Parkinson’s disease: a comprehensive review 170 177 IEEE Transactions on Biomedical Engineering (TBME)
Deep brain stimulation (DBS) is an effective therapy for Parkinson’s disease (PD). The success of the procedure depends heavily on the accurate placement of the electrode within the optimal therapeutic targets while avoiding vital structures that can cause adverse outcomes. Interventional guidance with medical imaging has greatly contributed to the development, outcomes, and safety of the procedure. With rapid technological advancements, it will further enhance the capacity and efficacy of the procedure. We present a comprehensive review on the state-of-the-art techniques in image-guided DBS surgery to treat PD, and discuss about the future directions on the topic. read more

An Integrated Robotic System for MRI-Guided Neuroablation: Preclinical Evaluation 170 152 IEEE Transactions on Biomedical Engineering (TBME)
This paper present preclinical trials of a robotic system for needle-based therapeutic ultrasound (NBTU) ablation of brain tumors under real-time magnetic resonance imaging (MRI) guidance. The system comprises of robotic manipulator and corresponding control electronics, the NBTU ablation system and applications for planning, navigation, and monitoring of the system. The integrated robotic system can place NBTU ablator at a desired target location in porcine brain and monitor the ablation in real-time via magnetic resonance thermal imaging (MRTI). The robotic system had a mean translational and rotational accuracy of 3.13±1.41 mm and 5.58±3.59° in 10 porcine trials. read more
