  • Title: 3D freehand ultrasound reconstruction based on probe trajectory.
    Author: Coupé P, Hellier P, Azzabou N, Barillot C.
    Journal: Med Image Comput Comput Assist Interv; 2005; 8(Pt 1):597-604. PubMed ID: 16685895.
    Abstract:
    3D freehand ultrasound imaging is a very attractive technique in medical examinations and intra-operative stage for its cost and field of view capacities. This technique produces a set of non parallel B-scans which are irregularly distributed in the space. Reconstruction amounts to computing a regular lattice volume and is needed to apply conventional computer vision algorithms like registration. In this paper, a new 3D reconstruction method is presented, taking explicitly into account the probe trajectory. Experiments were conducted on different data sets with various probe motion types and indicate that this technique outperforms classical methods, especially on low acquisition frame rate.
