选择合适的粘合剂对于动物fMRI至关重要. 平,薄的粘合层可以最大限度地降低易感器件,提高成像质量. 树脂和烯酸一般表现最好.
科学领域:
- 神经成像是一种神经成像.
- 生物材料是一种生物材料.
背景情况:
- 骨植入物粘合剂的敏感性人工物危害了动物的fMRI.
- 粘合性能显著影响成像质量.
研究的目的:
- 系统地评估粘合剂的类型,形状和磁场强度如何影响动物fMRI中的易感器件.
- 开发一个整合性评分系统,用于粘合剂的选择.
主要方法:
- 31种粘合剂被测试在7.0和9.4特斯拉使用T2*权重的EPI.
- 在体外和体内测试中测量了球形和平面形状的文物深度.
- 评估了粘附强度,并开发了一个整合性评分系统.
主要成果:
- 艺术品的尺寸是9.4T的两倍,而7.0T则是两倍.
- 球形的粘合形状产生了比平面形状更深的文物.
- 树脂,粘合剂和烯酸显示出比和水泥更优越的性能.
结论:
- 粘合剂的选择涉及到平衡处理,固化,强度和工件深度.
- 尽量减少文物需要在薄而平坦的层面上应用粘合剂.
- 整合性评分系统有助于对fMRI应用中的粘合剂进行分类.
