摘要：
A method adapted to diagnose airway obstruction in a subject is disclosed. The method comprises the following steps: providing plural cross-sectional ultrasound images of a region of the respiratory tract during the subjects normal breathing, wherein each ultrasound image has plural pixels and each pixel has a color scale value selecting a region of interest in each ultrasound image calculating a respective first statistic value. The pixels in each of the region of interest are identified to define a respective airspace region by the color scale values larger than or equal to the respective first statistic value. A respective width of the respiratory tract is calculated and based on the distribution of the pixels in the respective airspace region. The status about an airway obstruction in the subject is classified according to the second statistic value obtained by the calculation of the widths of the respiratory tract.本發明提供一種呼吸道寬度的測定方法,其步驟包含:提供一呼吸道區間的超音波影像,其中,每一該超音波影像具有複數像素點(pixel),且每一該像素點分別具有一色階值。再者,於該超音波影像中,圈選一興趣區域(region of interest),計算該興趣區域中該些像素點的色階值,取得一第一統計數值,並彙整該興趣區域中該些像素點的色階值大於或等於該第一統計數值者,定義為一空氣區域,而後,計算該空氣區域中該些像素點的色階值,取得一呼吸道寬度值。S1010~S1040‧‧‧呼吸道寬度測定方法之步驟
