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).
Claims15
A system for margin assessment of an ex-vivo tissue, comprising:
- a magnetic resonance imaging (MRI) scanner, controlled by a control unit;
- and
- a tissue container, for holding a sample of an ex-vivo tissue;
- said tissue container being sized such that edges of said tissue are forced against an inner surface of said tissue container to have a predetermined geometry, and wherein said MRI scanner is positioned relative to said tissue container such that said MRI scanner acquires images of said edges that have the predetermined geometry and which are in a sensitive region extending into a peripheral margin of said tissue;
- wherein said MRI scanner comprises a coil-magnet assembly comprising magnets, wherein said tissue, placed in said container, is placed under a constant static magnetic field (B0), which is induced by said magnets, and said container is positioned so the sensitive region is within a measured field of view (FOV) excited by one or more transmit/receive coils operative to generate a time-varying RF B1 electro-magnetic field pointing towards said tissue, and wherein said container is fixed on a moving table.
A system for margin assessment of an ex-vivo tissue, comprising:
- a magnetic resonance imaging (MRI) scanner controlled by a control unit;
- and
- a tissue container for holding a sample of an ex-vivo tissue, said tissue container being sized such that edges of said tissue are forced against an inner surface of said tissue container to have a predetermined geometry, and wherein said MRI scanner is positioned relative to said tissue container such that said MRI scanner acquires images of said edges that have the predetermined geometry and which are in a sensitive region extending into a peripheral margin of said tissue;
- and one or more markers in said tissue, wherein said container comprises one or more registration elements for fixing therein said one or more markers.
