The present invention relates to a method, a device, and a program for calculating a brachytherapy plan, and a brachytherapy apparatus. The method comprises: a step in which a computer obtains the number of radiation irradiation spots on the basis of radiation irradiation information (a radiation irradiation spot number obtaining step (S)); a step in which the computer obtains target area information from a body model of a patient generated on the basis of medical image data of the patient (a target area information obtaining step (S)); and a therapy plan calculating step (S) in which the computer calculates, on the basis of the radiation irradiation information and the target area information, the radiation irradiation spots to which radiation is irradiated and the time length of irradiation to each radiation irradiation spot.

A method of reducing an artifact by using structural similarity. The method includes at least: obtaining a plurality of input Computed Tomography (CT) images including a first CT image and a second CT image, generating an artifact map in which anatomical information is removed and artifacts information is remained, by subtracting the second. CT image from the first CT image, generating, by the computer, a structural similarity map between each CT image and the artifact map, and generating, by the computer, a final reconstructed image by comparing particular parts on images of a plurality of structural similarity maps with each other and selecting data of an input CT image which has been used to generate a particular part of a structural similarity map having a lowest degree of structural similarity, as data of a particular part on the final reconstructed image.

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.
