Disclosed are a device for extracting position emission tomography (PET)-magnetic resonance imaging (MRI) multiple images and a method thereof. According to a specific embodiment of the present invention, a final mask image is extracted from images obtained through PET and MRI imaging with different types of tissue contrast to prevent operation errors due to low quality or artifacts of the images obtained from conventional MRI imaging and, accordingly, stably extract the images while minimizing correction based on human intervention.
