A pilot study of the perceptual characteristics of ultrasonic textured images is described. Scans of four models performed on four real-time machines optimised for display of a normal liver were used. A trial with 22 observers indicated that the model that gave images closest to the liver image varied between machines. A second, paired similarity test with five observers using all the model images was performed, with a cluster analysis of a multidimensional scaling procedure. This suggested that the prominent features of the textural images are often more closely related to the machines than to the models. Considerable further work is needed to confirm these pilot results and to identify the visual cues that are most significant in textured images.
本文描述了一项关于超声纹理图像感知特征的初步研究。使用在四台针对正常肝脏显示进行优化的实时机器上对四个模型进行的扫描。一项针对22名观察者的试验表明，生成最接近肝脏图像的模型在不同机器之间存在差异。使用所有模型图像对五名观察者进行了第二项配对相似性测试，并对多维缩放程序进行了聚类分析。这表明纹理图像的突出特征通常与机器的关系比与模型的关系更密切。需要进行大量进一步的工作来证实这些初步结果，并确定在纹理图像中最重要的视觉线索。
