Algorithms for Automated Pointing of Cardiac Imaging Catheters
This paper presents a modified controller and expanded algorithms for automatically positioning cardiac ultrasound imaging catheters within the heart to improve treatment of cardiac arrhythmias such as atrial fibrillation. Presented here are a new method for controlling the position and orientation of a catheter, smoother and more accurate automated catheter motion, and initial results of image...

متن کاملA 4-DOF Robot for Positioning Ultrasound Imaging Catheters.
In this paper we present the design, fabrication, and testing of a robot for automatically positioning ultrasound imaging catheters. Our system will point ultrasound (US) catheters to provide real-time imaging of anatomical structures and working instruments during minimally invasive surgeries. Manually navigating US catheters is difficult and requires extensive training in order to aim the US ...
متن کاملReappraisal of ultrasound imaging of neonatal intravascular catheters.
Ultrasonography was successful in localising the tips of neonatal intravascular catheters and showed their precise relation to the cardiac chambers and major aortic branch vessels in 28 infants. Wherever adequate resources and training are available, this technique may provide a cheaper and non-invasive option, as well as giving additional information, than can be obtained from radiography.
متن کاملDespeckle Filtering Algorithms and Software for Ultrasound Imaging
It is well-known that speckle is a multiplicative noise that degrades image quality and the visual evaluation in ultrasound imaging. This necessitates the need for robust despeckling techniques for both routine clinical practice and teleconsultation. The goal for this book is to introduce the theoretical background (equations), the algorithmic steps, and the MATLABTM code for the following grou...
