  • Radiotherapy assistant apparatus for modulating build-up region of photon beam, radiotherapy system and method therefor
    Patent number: 10758746
    Abstract: Disclosed are a radiotherapy assistant apparatus for modulating a build-up region of a photon beam for a radiotherapy, a radiotherapy system including the radiotherapy assistant apparatus, and method for the radiotherapy system. The radiotherapy assistant apparatus for modulating a build-up region of a photon beam for a radiotherapy, including at least: a magnetic field generator that generates a magnetic field that has a direction perpendicular to a movement direction of the photon beam, the magnetic field generator is disposed on a movement route along which the photon beam moves toward a target portion of the radiotherapy; and a magnetic field intensity adjuster that adjusts an intensity of the magnetic field generated by the magnetic field generator. The magnetic field generator disperses secondary electrons that have particular energy levels equal to or lower than a preset value.

  • Tumor surface dose enhancing radiotherapy apparatus using magnetic field
    Patent number: 10532225
    Abstract: Disclosed is a tumor surface dose enhancing radiotherapy apparatus using a magnetic field, including a radiation beam generating unit that irradiates a radiation beam towards a tumor of a patient, a magnetic field generating unit that forms a magnetic field that is parallel to the radiation beam between the radiation beam generating unit and the tumor of the patient, and a control unit that controls a surface dose of the tumor by adjusting an intensity and an effective area of the magnetic field of the magnetic field generating unit.
