In fighting the coronary heart diseases, percutaneous coronary intervention is proved to be a powerful and reliable clinical procedure in the modern catheterization labs all over the world. Due to its minimally invasive characteristics, the procedure must be performed in the image-guided way, which makes this important skill very difficult to learn. To make the learning more accessible, a computer-aided...
This paper aims at using a newly developed robotic system to automatically deliver guidewires or catheters to the target site on percutaneous coronary interventions (PCIs) or electrophysiology interventions. An autonomous delivery strategy using electromagnetic tracking technology is introduced and phantom experiments are performed to validate this strategy. In order to advance the guidewire into...
In this paper, we propose a new computer aided diagnosis method of pulmonary nodules in X-ray CT images to reduce false positive (FP) rate under high true positive (TP) rate conditions. An essential core of the method is to extract and combine two novel and effective features from the raw CT images: One is orientation features of nodules in a region of interest (ROI) extracted by a Gabor filter, while...
