Figure 6 Color-coded map of calibrated contrast intensity (CI) in a patient with anterior myocardial infarction (MI). (Left) An HPD image in the apical four-chamber view shows a reduced contrast enhancement zone extending from the distal septum to cardiac apex. (Right) After the analysis with VoluMap, the mid-septum to apical region shows cool colors, indicating calibrated CI –18.0 dB. See text for details.
