Abstract

We describe a substantially improved NIRF-IVUS imaging system to overcome current technical limitations. We have implemented a hybrid rotary joint capable of rotational speeds up to 6,000rpm and developed a NIRF-IVUS imaging catheter with a robust dual-layer drive shaft and a reduced rigid length of 2mm with a catheter size <3.6F. NIRF-IVUS processing software was also improved by implementing a high-speed acquisition trigger and data streaming for fast recording speeds. NIRF-IVUS imaging at speeds of at least 30 fps in phantoms and in vivo arterial disease models will demonstrate the unique capabilities of IVUS-NIRF imaging of plaque pathobiology.
