Title: RADIATION DOSE ESTIMATING METHOD OF MRI-BASED COMPOSITE IMAGE USING LOOKUP TABLE
Abstract:
The present invention relates to a radiation dose estimating method and, more particularly, to a radiation dose estimating method of an MRI-based composite image using a lookup table. To this end, the above-described objective of the present invention is to provide: a step (S100) for generating a lookup table representing a linear attenuation coefficient of a region of interest from a CT image; a step (S120) for capturing at least two images of a patient from a T1 image, T2 image, and PETRA image through MRI equipment; a step (S140) for overlapping the captured images to generate a composite image; a step (S160) for indicating a boundary line of the region of interest on the composite image to distinguish the region of interest; a step (S180) for designating the linear attenuation coefficient of the lookup table on the distinguished region of interest; and a step (S200) for estimating a radiation dose on the basis of the composite image having the linear attenuation coefficient designated.
