摘要:
The present invention relates to a method and program for analyzing an intravoxel incoherent motion using a computer. According to an embodiment of the present invention, a method for analyzing an intravoxel incoherent motion using a computer comprises the steps of: receiving diffusion emphasized images obtained by a magnetic resonance imaging (MRI) image acquisition device, wherein the MRI image includes a plurality of images obtained according to a certain interval and diffusion emphasized gradient magnetic field intensity (S100) obtaining brightness data corresponding to each point in each diffusion emphasized image (S200) obtaining an input of selecting a certain point from a user, and extracting brightness data for each diffusion emphasized gradient magnetic field intensity (S300) at the certain point generating a first graph of the brightness data according to the diffusion emphasized gradient magnetic field intensity, based on the extracted brightness data (S400) and performing a curve adaptation process for the first graph according to a technique of analyzing an incoherent motion within a certain voxel to calculate a diffusion-related variable (S500). According to the present invention, the result of an intravoxel incoherent motion analysis performed by the computer can be obtained, thus simplifying the analysis of a diffusion emphasized image. For example, variables (a low-speed apparent diffusion coefficient (Dslow), a high-speed apparent diffusion coefficient (Dfast), a blood flow percentage (f), etc.) regarding the water molecule motion of a diffusion emphasized image can be simply obtained, thus increasing the utilization of various fields of a diffusion emphasized image.COPYRIGHT KIPO 2016본 발명은 컴퓨터를 이용한 복셀 내 비결집운동 분석방법 및 프로그램에 관한 것이다.본 발명의 일실시예에 따른 컴퓨터를 이용한 복셀 내 비결집운동 분석방법은, 자기공명영상취득장치를 통해 획득된 확산강조영상을 수신하되, 상기 확산강조영상은 특정한 간격 및 확산강조경사자장 세기에 따라 획득되는 복수의 영상을 포함하는, 단계(S100) 상기 각각의 확산강조영상 내 각 지점에 대응하는 밝기데이터를 획득하는 단계(S200) 사용자로부터 특정한 상기 지점을 선택하는 입력을 획득하여, 상
