Quantitative ultrasound analysis of vascular morphology for cancer assessment

Micro-tumor detection by quantifying tumor-induced vascular abnormalities
NIH/NCI : R01CA170665-01 (P. Dayton, UNC)
9/1/2012 - 8/31/2017
Data show that substantial changes in microvasculature structure occur after the arrival of only 10s to 100s of tumor cells, that these changes extend to vessels that are relatively large (hundreds of microns in diameter), and that microvascular changes extend well beyond tumor margins, even soon after the onset of disease. These unique microvascular “cancer signatures” provide us with a means to overcome traditional resolution limitations which otherwise impair micro-tumor detection.
A Needle Guidance System for Hepatic Tumor Ablation That Fuses Real-Time Ultrasound

(2) Specifying a surgical path and predicting both donor and recipient outcome based on the surgical path complexity, graft volume, and the path’s effect on the liver’s vascular network. (3) Assessing liver regeneration in the donor and the recipient by quantifying volume and vessel network change by registering the donor’s pre-operative liver vessel network with the donor’s and the recipient’s post-operative liver vascular networks six weeks following the operation.
