Fig. 8.
Contrast images of a flow channel embedded in a tissue-mimicking phantom with and without MBs. Amplitude-modulated NLC images acquired with (left) a standard 21 MHz transducer and (middle) the HF array of the DF probe (DF-HF). (right) Images acquired in SpHI-mode using the DF probe. Color-rendered contrast images are overlaid on interleaved gray-scale B-mode images. Gray-scale micro-ultrasound B-mode images and the color-rendered images are displayed in −50 dB and −35 dB dynamic ranges, respectively. The ROIs used to compute CTR are indicated by the white box on the image. The depth axis is relative to the probe surfaces and identical for all images. Image axes are in millimeters.
