Biopsy has become a cornerstone of modern medicine and most modern biopsies are
performed percutaneously using image guidance, typically computed tomography or …

With the recent advances in magnetic resonance (MR) labeling of cellular therapeutics, it is
natural that interventional MRI techniques for targeting would be developed. This review …

Cardiac electrophysiology is an effective treatment for atrial fibrillation, in which a long,
steerable catheter is inserted into the heart chamber to conduct radio frequency ablation …

Patient motion during an MRI exam can result in major degradation of image quality, and is
of increasing concern due to the aging population and its associated diseases. This work …

Catheters integrated with microcoils for electromagnetic steering under the high, uniform
magnetic field within magnetic resonance (MR) scanners (3–7 Tesla) have enabled an …

Active instrument visualization strategies for interventional MR angiography (MRA) require
vascular instruments to be equipped with some type of radiofrequency (RF) coil or dipole RF …

A novel two‐element, catheter‐based phased array coil was designed and built for both
active MR device tracking and high‐resolution vessel wall imaging. The device consists of …

A novel magnetic resonance (MR)-tracking method specifically developed to locate the
ferromagnetic core of an untethered microdevice, microrobot, or nanorobot for navigation or …

Catheters and other endovascular access tools have long been used in the art as medical
devices to advance therapeutic agents to an anatomic point of interest for examination, diag …

In many cases, radio-frequency catheter ablation of the pulmonary veins attached to the left
atrium still involves fluoroscopic image guidance. Two-dimensional X-ray navigation may …
