"Conformal Spectroscopy" is a general method for the acquisition of accurately localized NMR spectra from noncuboidal regions with optimum signal-to-noise ratio (SNR). The method is based upon the localization of volumes defined by a number of intersecting oblique slices and may be implemented using standard imager hardware. Conformal techniques can enhance many existing localization sequences such as ISIS (31P) and STEAM (1H) resulting in typical SNR improvements of around 1.8, equivalent to a more than threefold reduction in acquisition time. Applications include in vivo tumor spectroscopy.
“共形光谱法”是一种从非长方体区域获取具有最佳信噪比（SNR）的精确定位核磁共振谱的通用方法。该方法基于由多个相交斜切片定义的体积的定位，并且可以使用标准成像硬件来实现。共形技术可以增强许多现有的定位序列，如ISIS（31P）和STEAM（1H），从而使典型的信噪比提高约1.8，相当于采集时间减少三倍以上。其应用包括体内肿瘤光谱分析。
