| 目的 研究在不同频率探头的情况下,同一种组织的超声纹理参数的变化,探讨B 超探头的工作频率对B超图像纹理参数数值的影响。方法 分别采用3.5 兆赫及5 兆赫的探头对10 只新西兰家兔的肝脏B超图像进行采集,并进行图像纹理分析。结果 发现对应的各项纹理参数其平均值均有不同程度的变化。结论 作为定量分析的一种方法,B超图像纹理参数的数值是与B超探头的工作频率有关的。 |

| Purpose The changes of the ultrasonic texture parameters of the same types of tissue are investigated while using the different frequancy probes. Furthermore the effects of the working frequancy of the B mode scanner probes on the texture parameters of B mode tomograms are discussed. Methods The B mode tomograms of 10 New Zealand rabbits lives are picked up using 3.5MHz and 5MHz probes successively, and then the image texture analysis is proceeded.Results The results show that the mean values of every corresponding texture parameters all changed in the different level.Conclusion As a method of quantitative analysis the values of texture parameters of B mode images is related on the working frequancy of B scanner probe. It is necessary to understand the rules of they variousness when using these parameters for the reference of clinical diagnosis. |
