Abstract
A novel acquisition and processing method that enables single snapshot wide field imaging of optical properties in the Spatial Frequency Domain (SFD) is described. This method makes use of a Fourier transform performed on a single image and processing in the frequency space to extract two spatial frequency images at once. The performance of the method is compared to the standard six image SFD acquisition method, assessed on tissue mimicking phantoms and in vivo. Overall both methods perform similarly in extracting optical properties.
摘要
描述了一种新颖的采集和处理方法，该方法能够在空间频域（SFD）中实现光学特性的单快照宽场成像。此方法利用对单个图像执行的傅里叶变换并在频率空间中进行处理，以一次提取两个空间频率图像。将该方法的性能与标准的六图像SFD采集方法进行了比较，在组织模拟体模和体内进行了评估。总体而言，两种方法在提取光学特性方面表现相似。
