摘要： Provided are a phantom for standardizing ultrasonograph and a method of obtaining an ultrasonographic image using the phantom, and more particularly, a phantom for measuring fat content in a target organ as a gray level distribution using an ultrasonographic image and assessing the accuracy of ultrasonograph and a method and apparatus for obtaining a standardized ultrasonographic image using the phantom. Since the photographing characteristics of the ultrasonograph are readjusted using a phantom which comprises a phantom part including a strong ultrasonic echo material and a weak ultrasonic echo material, which create a gray level distribution in ultrasonography, in a specific composition and ratio, and assesses the accuracy of the ultrasonograph by comparing the composition and ratio of the materials with a composition and ratio of a gray level in an ultrasonographic image, the characteristics of the ultrasonograph can be standardized and fat content in a body part can be quantitatively measured without being affected by photographing techniques and conditions.

摘要： 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.
