To exploit fully the imaging data derived from both angiography and intravascular ultrasound (IVUS), combined visualization is needed. Although this visualization has been available in the research environment for the last decade or so, clinical implementation is still pending. Recent improvements in computer hardware and software (algorithms), improved angiography and IVUS technologies, and a total digital imaging workflow could bring integrated IVUS/angiography imaging into the catheter laboratory in the near future.
