Vessel Segmentation In High-Frequency 2d/3d Ultrasound Images

Characterizing the microvascular architecture has a wide range of medical and biological applications in the fields of angiology, oncology and dermatology. We propose a method to segment vessels in 2D temporal sequences and in 3D images using high-frequency ultrasound (25-50 MHz). The method takes as input the native ultrasound images, and detects the vessels based the intensity and the dynamical decorrelation. It enables to characterize the vascularization of tumors or organs whenever a Doppler mode is not available.
