Abstract
A method and a device for measuring a pulmonary nodule volume using a dual-energy subtraction image are provided. The method includes: (a) obtaining a dual-energy subtraction image of a chest; (b) setting a specific region including a pulmonary nodule region in the obtained dual-energy subtraction image; (c) interpolating a gray level trend of a region surrounding the pulmonary nodule region into the pulmonary nodule region using a fitting function; and (d) measuring the pulmonary nodule volume by subtracting the interpolation result from the gray level data of the pulmonary nodule region. Accordingly, when it is desired to measure the pulmonary nodule volume using the dual-energy subtraction image, information on the thickness of the pulmonary nodule is obtained from the characteristic of the dual-energy subtraction image, and the pulmonary nodule volume is accurately measured by correcting errors at the border of the pulmonary nodule region using the fitting function.
