摘要

A set of intravascular ultrasound (IVUS) related systems, apparatuses and methods are disclosed. New catheter designs including contrast agent introduction subsystems and/or Doppler subsystems are disclosed. Methods for acquiring and analyzing Doppler data from intravascular ultrasound (IVUS) catheters are disclosed. RF-based detection of blood and/or contrast agents such as micro-bubbles are disclosed. Methods for frame-grating image data analysis permitting frame registration before, during and after a contrasting effect is imposed on a system being imaged are disclosed. Methods for difference imaging for contrast detection are disclosed. Methods for quantification and visualization of IVUS data are disclosed. And methods for IVUS imaging are disclosed.
