    • It is intended to provide a gel for an ultrasonic phantom which has favorable ultrasonic characteristics that can be sustained over a long period of time without alteration and is free from bacterial contamination, denaturation, putrefaction, etc. Namely, a gel for an ultrasonic phantom which comprises a segmented polyurethane gel having alkylene oxide segments, which are mostly or entirely in the form of a liquid at room temperature, and a nonvolatile organic gel expansion medium, which would not participate in the reaction of the urethane, contained therein. Owing to the nonvolatile organic gel expansion medium, the liquid segments, etc. are maintained in the spread state and thus the spaces among the segments are enlarged, which brings about favorable ultrasonic characteristics such as ultrasonic attenuation rate and transmission speed. Since the content of the expansion medium shows no temporal change, these favorable ultrasonic characteristics are maintained over a long period of time. Because of containing the organic gel expansion medium, the gel for an ultrasonic phantom is free from bacterial contamination, denaturation, putrefaction, etc.
    • 旨在提供一种超声波体模的凝胶,该凝胶具有良好的超声波特性,其能够在不改变的情况下长时间地维持,并且没有细菌污染,变性,腐败等。也就是说,用于超声波体模的凝胶 包括在室温下大部分或全部呈液体形式的环氧烷链段的分段聚氨酯凝胶和不参与其中所含氨基甲酸酯反应的非挥发性有机凝胶膨胀介质。 由于非挥发性有机凝胶膨胀介质,液体段等保持在扩展状态,因此区段之间的空间增大,这导致超声波衰减速率和传输速度等良好的超声波特性。 由于扩展介质的内容不显示时间变化,所以这些有利的超声波特性在长时间内保持。 由于含有有机凝胶膨胀介质,超声波模型的凝胶无细菌污染,变性,腐败等。
