Acoustic Angiography: A New Imaging Modality for Assessing Microvasculature Architecture

Figure 6

Multiple comparisons of 3D tissue volumes: two containing a tumor (left) and two healthy controls (right). The bottom images are acoustic angiography maximum intensity projections, while the top images are b-mode acquisitions of the same tissue volumes. The tortuous and chaotic morphologies of the vessels in the presence of a lesion are contrasted by the relatively homogeneous vasculature in the healthy volume (tumor boundaries delineated in acoustic angiography image with dotted line). Image volumes = ~0.75 × 1.25 × 1.5 cm (axial, lateral, and elevational). A cartoon on the right indicates the imaging location and orientations of image volumes.
