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 an in vivo radiation amount measuring instrument. An in vivo radiation amount measuring instrument according to the present invention comprises: a main body elongated along an in vivo inserting direction and capable of supplying a fluid; an expanding part having at least a portion thereof fixed or connected to the main body and capable of being expanded and contracted by means of the outflow/inflow of the fluid; and a radiation measuring part disposed on the expanding part and measuring the amount of surface radiation distribution on in vivo tissue which the expanding part contacts by expanding.
