Abstract
An image catheter is introduced into the venous system and is maneuvered through the venous system to points adjacent to sections of arteries to be imaged. The arterial segments are then imaged from those adjacent points in the venous system. Ideally an ultrasound imaging catheter with a diameter of 7-10 French (2.3 mm-3.3. mm) operating at a frequency between 15 and 20 MHz is used.
