Disclosed is an apparatus for measuring the distribution of radiation dose emitted from a brachytherapy insertion tool, the apparatus including a housing having defined therein a measurement space in which the brachytherapy insertion tool is located, a fluorescent member disposed at the housing, the fluorescent member being configured to react with radiation emitted to the measurement space and to emit light, a camera disposed in the housing, and a cover coupled to one surface of the housing, the cover being configured to cover the fluorescent member. The portion of the fluorescent member to which radiation from a radiation source of the brachytherapy insertion tool is applied reacts with the radiation and generates light, brightness of the light varies depending on distribution of the radiation, and the position at which the light is bright is calculated to measure the direction in which the brachytherapy insertion tool has no shielding.

Apparatus and method for measuring distribution of radiation dose from brachytherapy radiation source

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.
