Phased-Array Coil for Image-Guided Treatment of Occlusive Arterial Disease

In this study we propose a novel phased-array intravascular imaging coil consisting of two orthogonal solenoids located at the tip of a catheter. Unlike previous opposed-solenoid designs, the configuration is able to obtain images ahead of the catheter when it is oriented in the same orientation as the static magnetic field. This is of particular interest when guiding a catheter-based device through occlusive lesions during percutaneous treatment. A design is presented and the sensitivity volume of the coils is described through simulation and phantom studies. An in-vivo application in a porcine femoral artery is also presented.
