With optical cameras, many interventional navigation tasks previously relying on EM, optical, or mechanical guidance can be performed robustly, quickly, and conveniently. We developed a family of novel guidance systems … Read more

The Clear Guide ONE (Clear Guide Medical, Baltimore, MD) is a Computer-Assisted Instrument Guidance (CAIG) device, which optically tracks a procedure needle and calculates a “projected” path, which is displayed … Read more

This study explores the potential of a new device, the Clear Guide ONE system (CLEAR GUIDE MEDICAL, Baltimore, MD), for improved percutaneous ultrasound-guided vascular access.

We characterize the performance of an ultrasound+computed tomography image fusion and instrument guidance system on phantoms, animals, and patients. The system is based on a visual tracking approach. Using multi-modality … Read more

Background: Ultrasound guidance for needle-based interventions is a widespread approach to assist in precise targeting of anatomical structures for diagnostic (e.g., for biopsies) or therapeutic (e.g., tumor ablation or anesthesia) … Read more

This work explores the suitability of low-cost sensors for “serious” medical applications, such as tracking of interventional tools in the OR, for simulation, and for education. Although such tracking – … Read more

Handheld ultrasound is useful for intra-operative imaging, but requires additional tracking hardware to be useful in navigated intervention settings, such as biopsies, ablation therapy, injections etc. Unlike common probe-andneedle tracking … Read more
