ABSTRACT
Data Acquisition VH-IVUS images are obtained with a commercially available console [IVG (InVision Gold) that has integral pcVH software or S5 that has integral VIAS software, both Volcano Corporation, Rancho Cordova, California, U.S.]. Both consoles are interfaced with either a phased-array transducer (Eagle EyeTM
20 MHz catheter, Volcano Corporation, Rancho Cordova, California, U.S.) or, in the future, with a developed mechanical transducer (RevolutionTM 45 MHz, Volcano Corporation, Rancho Cordova, California, U.S.). The integral software allows VH analysis to be performed online in the catheterization laboratory. The IVUS catheter is positioned distally in the coronary artery and then withdrawn at a speed of 0.5 mm/sec using an automated pullback device. VH-IVUS data are acquired simultaneously with the gray scale IVUS data; however, ECG-gating is used to select frames for VH-IVUS analysis.
