“共形光谱学”是一种从非立方体区域获取精确定位的NMR光谱的通用方法，具有最佳信噪比（SNR）。该方法基于由多个相交的倾斜切片限定的体积的定位，并且可以使用标准成像器硬件来实现。保形技术可以增强许多现有的定位序列，如ISIS（31 P）和STEAM（1H），导致典型的SNR提高约1.8，相当于采集时间减少三倍以上。应用包括体内肿瘤光谱学。
“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.
