C-arm fluoroscopy is ubiquitous in contemporary surgery, but it lacks the ability to accurately reconstruct three-dimensional (3D) information. A major obstacle in fluoroscopic reconstruction is discerning the pose of the x-ray image, in 3D space. Optical/magnetic trackers tend to be prohibitively expensive, intrusive and cumbersome in many applications. We(More)
PURPOSE Brachytherapy (radioactive seed insertion) has emerged as one of the most effective treatment options for patients with prostate cancer, with the added benefit of a convenient outpatient procedure. The main limitation in contemporary brachytherapy is faulty seed placement, predominantly due to the presence of intra-operative edema (tissue(More)
We propose a software and hardware integration strategy for MRI-guided robotic prostate intervention using an open network communication protocol. In the MRI-guided robotic intervention, the robot, navigation software and MRI scanner communicate one to another via Ethernet to exchange various data e.g. robot position, commands and MR images. Since the(More)

INTRODUCTION Chronic migraines (CM) afflict approximately 16.6% of adults and negatively impact quality of life. Furthermore, although some CM can be treated with steroids, occipital nerve block, radiofrequency therapy, or medical therapy, approximately 15% of patients remain refractory to treatment. We explore focused high-intensity ultrasound (HIU) as a(More)
INTRODUCTION Vincristine is a commonly used chemotherapeutic agent but is associated with debilitating peripheral neuropathy that is often refractory to traditional medication. We explore 1 neuromodulatory option, high-intensity focused ultrasound (HIFU), which may work by altering neuronal activity. Thus, we focus on the efficacy of HIFU in treating(More)
