Device for generating magnetic field and method for controlling same

A radiation and magnetic field generating apparatus irradiating photon beam radiation to in-body affected tissue of a subject, the apparatus comprising:

• a radiation generating unit configured to irradiate the photon beam radiation to the subject and to induce generation of secondary electrons in an area of the subject where the photon beam radiation is irradiated;
• a magnetic field generating unit, which is provided to be inserted into a body, which includes an insertion structure for forming a low-density space, and which is configured to form a magnetic field in an area in which the secondary electrons are generated;
• and
• a synchronization control unit configured to:
• control formation of the magnetic field such that at least part of the secondary electrons moves to the low-density space based on a relationship between an area where the photon beam radiation is irradiated and a location of an affected part;
• and
• control the formation of the magnetic field such that the secondary electrons move while avoiding normal tissue adjacent to the affected tissue,
• wherein a shape of the insertion structure is determined based on the relationship between the area where the photon beam radiation is irradiated and the location of the affected part.

A method of controlling a radiation and magnetic field generating apparatus irradiating photon beam radiation to an in-body affected tissue of a subject, the method comprising:

• irradiating the photon beam radiation to the subject through a radiation generating unit of the magnetic field generating apparatus;
• inducing generation of secondary electrons in an area of the subject irradiated with the photon beam radiation through the radiation generating unit of the magnetic field generating apparatus;
• and
• forming a magnetic field in an area where the secondary electrons are generated, through the magnetic field generating unit of the radiation generating apparatus,
• wherein the forming of the magnetic field includes:
• forming the magnetic field such that at least some of the secondary electrons move while avoiding the affected tissue based on a relationship between an area where the photon beam radiation is irradiated and a location of an affected part, and
• wherein the forming of the magnetic field includes:
• allowing the pulse power to be supplied to the magnetic field generating unit such that the magnetic field is formed in a state where a caloric value generated by the magnetic field generating unit is not greater than a predetermined value.
