Abstract: A medical phantom is an object that models at least a part of the human body by using unit blocks, wherein the unit blocks include: a first unit block having a hexahedral shape of which the inside is empty; and a second unit block. The second unit block has a shape, of which the inside is empty, different from the hexahedral shape The second unit block also has ridges formed at the upper end thereof for stud-and-tube coupling, and has furrows formed at the lower end thereof and enabled to be coupled to the ridges.

Abstract: A phantom for measuring thickness of a thin layer and a method of using thereof. The phantom may include a non-scattering muscle mimicking material having a flat top surface; a plurality of soft tissue mimicking thin layers placed in a first area, which is at least a part of a top surface of the non-scattering muscle mimicking material, and having thicknesses different from each other; and an anechoic blood mimicking liquid material placed in an area other than the first area among an entire area of the top surface of the non-scattering muscle mimicking material and on a top surface of the plurality of soft tissue mimicking thin layers.

Abstract: A magnetostrictive phased array transducer for transducing shear horizontal bulkwaves including a plurality of magnetostrictive members each having a bottom surface of a plate-shaped structure made of a ferromagnetic material, which is mounted to be adhered closely to the surface of a mounting place; an insulator disposed on a side surface of each magnetostrictive member; a meander coil having a plurality of coil lines extended in the direction parallel with the bottom surface on each insulator, wherein adjacent coil lines are connected so that current flows in the opposite directions to each other, thereby generating a dynamic magnetic field with respect to each magneto strictive member; and a magnet mounted to generate a static magnetic field perpendicular to the dynamic magnetic field. When the current is supplied to the meander coil, a plurality of magnetostrictive members generate a plurality of shear horizontal bulkwaves while being deformed by the magnetostriction effect.
