Abstract
A system for margin assessment of an ex-vivo tissue (25) is provided, including a magnetic resonance imaging (MRI) scanner (14) controlled by a control unit (12), and a tissue container (24) for holding a sample of an ex-vivo tissue (25). The MRI scanner (14) includes a coil-magnet assembly (31) including magnets (34), wherein the tissue (25), placed in the container (24), is placed under a constant static magnetic field (Bo), which is induced by the magnets (34), and the container (24) is positioned so the sensitive region is within a measured field of view (FOV) excited by one or more transmit/receive coils (38) operative to generate a time-varying RF B1 electro-magnetic field pointing towards the tissue (25), and wherein the container (24) is fixed on a moving table (40).
