| 中文摘要: |
| 目的 为脂肪肝病变的诊断提供一种定量分析的手段。方法 本文针对实际采集的肝脏B 超图像进行了研究,采用灰度共生矩阵法对肝脏B 超图像进行了特征提取,对各个特征参数进行了计算和分析。结果与结论 图像的处理分析结果表明正常肝与脂肪肝的能量、熵、反差分矩有着显著的差异,对于区分图像有很强的描述能力。 |

| Objective To provide a method of quantitative analysis in diagnosing fatty liver. Methods B2scan ult rasonicimage of liver , ext racts some features from B-scan ultrasonic image of fatty liver based on gray level Co-occurrence mat rixwas studied and these features were calculated and analyzed. Results and Conclusion The emulating result of these imageprocessing is that these features , including angular second moment , ent ropy , and inversed differential moment , differentprominently between normal liver and fatty liver , and can be used to distinguish B-scan ultrasonic image primly. |
