Superharmonic imaging of a xenograft mouse tumor showing B-mode images acquired with the DF-HF array, SpHI contrast images, and the color-rendered SpHI images overlaid on the gray-scale micro-ultrasound B-mode images. Panels show pre- and post-injection images. Image artifacts due to trigger crosstalk are indicated by arrowheads on the SpHI image. The two ROIs used to compute CTR in SpHI and B-mode images are indicated by the white boxes on the SpHI image. All gray-scale images are displayed with −50 dB dynamic range. The color-rendered SpHI images are displayed in a −35 dB dynamic range in the overlay panel. The depth axis is relative to the probe surface and identical for all images. Image axes are in millimeters.
