Abstract The back plates of master violins at the Ashmolean Museum in Oxford and the Museo del Violino in Cremona were analyzed by portable magnetic resonance imaging with the NMR-MOUSE in terms of depth profiles. Distributions of transverse NMR relaxation times were recorded versus depth at points of small curvature across the violin back plates providing insight into the physical states of the materials. Their analysis reveals the effects of surface treatments, wood treatment, and possible wood degradation. While conclusions about the type of treatment cannot be drawn, the profiles report surprising differences between the violins from the museums in Oxford and Cremona.

通过非破坏性 MRI 深度分析比较历史小提琴

摘要 通过便携式磁共振成像和 NMR-MOUSE 对牛津阿什莫林博物馆和克雷莫纳小提琴博物馆的大师级小提琴背板进行深度剖面分析。在小提琴背板上的小曲率点处记录横向 NMR 弛豫时间的分布与深度的关系，从而深入了解材料的物理状态。他们的分析揭示了表面处理、木材处理和可能的木材降解的影响。虽然无法得出关于治疗类型的结论，但档案报告了牛津和克雷莫纳博物馆的小提琴之间令人惊讶的差异。
