Method and system for obtaining an image of extracting a phalangeal boundary are provided to improve accuracy for extracting the phalangeal boundary by removing a background gray level trend due to a soft tissue of a finger when extracting the phalangeal boundary by using an X-ray image of a hand. A method for obtaining an image of extracting a phalangeal boundary includes the steps of: setting a target region for extracting the phalangeal boundary from an X-ray image of a hand(S12); obtaining an image by removing a background gray level due to a soft tissue from the target region(S13); and drawing a peripheral boundary image of a phalangeal from the image without the gray level(S14). The step of obtaining the image without the gray level includes the steps of: extracting a peripheral boundary image of a finger in the target region(S131); fitting to interpolate the gray level of the soft tissue of the finger of the peripheral boundary image into a phalangeal region(S132); and subtracting a gray level of the image obtained as a result of the fitting from the gray level of the peripheral boundary image(S133).
