    Recently, we described a reconstruction method of the blood vessel network (BVN) by 3D thinning to detect vessels bifurcations, which is applied to the control of microbubbles in vivo. However, that method did not include blood flow directions and was only verified on a very simply shaped artificial blood vessel. In this paper we propose a much improved system, this time including blood flow directions and, importantly, assessing the reconstruction correctness by introducing an abstraction method for the BVN. Such a model is then analyzed through graph theory and error patterns for auto-correction of the reconstructed BVN. Data was acquired by a Philips xMATRIX iU22 3D-capable echography and a matrix array probe (X6-1). Flow directions were obtained by using colour Doppler information. Additionally, we conducted several validating experiments: first, we performed an in silico trial, involving a simulated three-dimensional vessel of realistic shape. Then, we proceeded in vitro by acquiring volume data from an artificial capillary with multi-bifurcations made of poly(vinyl alcohol) by grayscale lithography whose diameter ranges from 0.5 to 2.0mm and with different flow velocities. Results show that our system successfully reconstructed the corresponding BVNs. ISCA
