    • 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.
    • 提供了一种使用双能量减影图像测量肺结节体积的方法和装置。 该方法包括:(a)获得胸部的双能量减影图像; (b)在获得的双能量减影图像中设定包括肺结节区域的特定区域; (c)使用拟合函数将肺结节区域周围的区域的灰度级趋势内插到肺结节区域; 以及(d)通过从肺结节区域的灰度级数据中减去内插结果来测量肺结节体积。 因此,当希望使用双能量减影图像测量肺结节体积时,从双能量减影图像的特征获得关于肺结节厚度的信息,并且通过以下方式精确地测量肺结节体积: 使用拟合函数校正肺结节区域边界的误差。
