    Novel technique for three-dimensional
    visualization and quantification of deformable,
    moving soft-tissue body parts.





    Lancet, vol.356, July 8, 2000, p.127-131.


      


    Three
    dimensional (3D) imaging of delicate, moving soft
    tissue body parts is difficult – e.g. understanding
    of the muscles that control lip movements is based
    largely on histological and cadaveric studies. The aim of the authors was to develop an
    innovative scanning technique for imaging and
    reconstruction of dynamic orofacial morphology by
    use of 3D and four-dimensional (4D i.e. 3D plus
    time) ultrasonography.




      

    To avoid
    deformation of delicate orofacial structures, a
    water-bath with an accoustic window was devised. The orofacial part was immersed in the bath
    throughout scanning, and a timer was used to
    synchronise lip-movements with the 4D scan.




      

    The
    findings were that, the 4D views showed the
    functional differences in superficial and deep
    muscle groups of the lips and clearly showed the
    changes occurring with movements of the lips and
    mouth.




      

    The authors
    have developed a prototype device and with further
    refinement of the device, this technique may offer a
    new way of dynamically imaging and quantifying many
    soft-tissue parts in 3D without deforming structure
    or disturbing function.
