Abstract: Disclosed are a method of reducing artifacts by using structural similarity and a program thereof. The method includes obtaining a plurality of input CT images by a computer, generating an artifact map by comparing the plurality of input CT images with each other by the computer, generating a structural similarity map between each CT image and the metal artifact map by the computer, and generating, by the computer, a final reconstructed image by comparing specific points on a plurality of structural similarity maps with each other and applying data of an input CT image used to generate a structural similarity map having a lowest degree of structural similarity as data of a specific point.

Abstract: The present invention relates to a customized surgical guide device and a customized surgical guide generating method and program. A customized surgical guide generating method comprises the steps of: acquiring body surface data and treatment area data from medical image data by a computer; a first shape data generating step, wherein the first shape data is data which corresponds to the shape of the body part cover; a target point setting step of setting one or more target points; setting individual first points on the body surface accessible to the target point with a medical tool; setting a guide tube length on the basis of a distance from the first point to the target point; and generating final shape data in which one or more guide tubes are combined to the first shape data by applying the guide tube length to the first point.

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.

Abstract: 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 (S200)); 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 (S400)); and a therapy plan calculating step (S600) 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.
