The present invention relates to an intra cardiac echo (ICE) imaging device, an ICE imaging system and method for assessing coronary circulation using an ICE probe. An image (1) of a cardiac region is received, wherein the image provides at least one or more coronary vessels (3) and/or at least one heart chamber (5)； at least one region of interest (ROI) (7) within the image is defined； imaging parameters of an ICE probe (9) are received； and at least one of a location, an orientation and access path of the ICE probe relative to the RO is calculated based on anatomical content in the ROI and/or in the cardiac region and the imaging parameters of the ICE probe, wherein the calculated location and/or orientation and/or access path is optimal for imaging of the at least one ROI.
