Method and apparatus for supporting diagnosis of region of interest by providing comparison image

An apparatus for supporting a diagnosis of a region of interest (ROI), the apparatus comprising:

• a medical imaging machine comprising:
• a memory configured to store instructions therein;
• and
• at least one processor configured, upon execution of the instructions, to:
• capture a plurality of images,
• analyze the plurality of images,
• determine an image where the ROI is detected, from among the plurality of images as a standard image,
• extract at least one image, which is associated with the standard image, from among the plurality of images as at least one candidate image,
• compare the ROI of the standard image and a corresponding area of the at least one candidate image, respectively, and
• select at least one image, which is contrasted from the standard image by more than a pre-set degree, from among the extracted at least one candidate image as at least one comparison image for supporting a diagnosis of the detected ROI of the standard image based on a result of the comparison;
• and
• a display configured to display the standard image and the at least one comparison image.
