Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technology for accurately detecting an internal radiation dose for each organ from an actual medical image by administering a radiation source to a subject so as to be imaged.SOLUTION: A radiation dose measurement method according to the present invention includes: a step of imaging a morphologic image of a subject; a step of storing organ area information by determining and storing an organ from the morphologic image; a step of summarizing a degree of integration of radiopharmaceuticals for the whole body of the subject from a functional image and calculating the radiation for each degree of integration of the radiopharmaceuticals from this combined values and a radioactive agent and finding an organ integration degree combined value; and a step of finding the radiation dose for each organ by multiplying the radiation per each degree of integration by an organ integration degree combined value and finding the radiation dose for each organ.SELECTED DRAWING: Figure 2
