Energy projection (EP) images of various contrast agents infused through the tissue-mimicking phantom. Different concentrations and pressures are presented before (left two columns) and after (right two columns) time-domain averaging, TDA. The dynamic range is 30 decibels, dB. Images were normalized to the 0.3%, 700 kPa droplet trial pre-TDA. The red dotted areas indicated regions of interest for CTR calculations.
