| titleOfInvention | Method and structure capable of forming conical and dome-shaped gradient magnetic field as well as targeting therapy equipment |
| abstract | The invention discloses a method and a structure capable of forming a conical and dome-shaped gradient magnetic field as well as targeting therapy equipment. The method comprises the following steps of: step 1, using a square permanent magnet as a main magnet body, and using two square permanent magnets which are lower than the main magnet body as auxiliary magnet bodies, wherein the auxiliary magnet bodies are arranged at both sides of the main magnet body; and a magnetic moment direction of the main magnet body is the same as that of a first auxiliary magnet body and a second auxiliary magnet body; and step 2, respectively arranging wedged ferromagnetic blocks on the top surfaces of the two auxiliary magnet bodies by means that the inclined surfaces of the wedged ferromagnetic blocks face upwards, one square surface of each wedged ferromagnetic block is adhered to the top surface of the corresponding auxiliary magnet body, and the other square surface of each wedged ferromagnetic block is adhered to the side surface of the main magnet body, so that the two wedged ferromagnetic blocks are symmetrically distributed at both sides of the main magnet body in a splayed manner; and the conical and dome-shaped gradient magnetic field is formed at the top of the main magnet body. The magnet structure provided by the invention can be used as a magnetic drug targeting guide magnet body, so that magnetic drug grains are controlled within a smaller space according to the distribution of a compact magnetic field and gradient of the magnetic field; and the positioning accuracy of targeting therapy is improved. |
