Application of microvascular imaging to assess the angiogenic biomarker of cancer: Maximum intensity projections of 3-D acoustic angiography imaging of microvasculature for healthy (control) tissue and tissue surrounding fibrosarcoma tumors in a rat model. Dotted circles indicate approximate location of solid tumor mass, and field of view is approximately 2.5×2cm. Reproduced with permission from R. C. Gessner, S. R. Aylward, and P. A.
