Automated Generation of Reliable Blood Velocity Parameter Maps from Contrast-Enhanced Ultrasound Data

Figure 3

Parametric perfusion analysis of mouse tumors. Graphs of nine individual in vivo measurements displaying the calculated mean MB velocity of different pixel resolution. The arrow indicates the parameter map with the best pixel resolution, having a mean MB velocity falling into the 95% confidence interval of the MB velocity calculated for a single segmentation, which is covering the whole tumor (tumor mean). The high variability in between the measurements shows the need for an individual assessment of each tumor. The number of pixels on the top of each graph displays the size of the tumor segmentation.
