Abstract

At present most systems used for three-dimensional reconstruction (3-D) of two-dimensional intracoronary ultrasound (ICUS) images are based on an image acquisition with a pull-back device which withdraws the catheter with a constant speed, not taking account of cardiac motion and coronary dynamics/pulsation. Cyclic changes of the vessel dimensions and the movement of the catheter inside the vessel result in artifacts and inaccuracies of quantitative measurements. This phenomenon limits accuracy and resolution when an attempt of 3-D reconstruction is performed, since images obtained in different phases of the cardiac cycle are compiled. To overcome these limitations we developed a custom-designed pull-back device driven by a stepping motor, which is controlled by a steering logic ensuring an ECG-gated image acquisition.
