SimpleSENSEreconstruction
- 简单SENSE图像重建，即使通过反傅里叶变换重建出最终图像-The data was acquired from 4-channel array coil using EPI sequence (2-shot, matrix: 64X64, TE: 50 ms) at a 1.5T scanner. The code estimates the coil sensitivity profiles directly from the image with anatomical contrast b
T2F
- T2F子函数，在做傅里叶变换时调用。我一开始编程序时忘了加它，结果WARN ME 说未定义T2F。-T2F subroutine, called when doing Fourier transform. I started to compile the program forgot to add it, and the result is undefined WARN ME said T2F.
F2T
- F2T子函数，在做傅里叶变换时调用的函数。也可做成脚本文件。-F2T subroutine, called when doing Fourier transform function. Can also be made into a scr ipt file.
AnalogVoiceSignal
- 观测实时模拟信号（语音）的频谱 用音频设备采集一段语音，将语音存为.wav格式。对wav文件作分段傅里叶变换分析。语音是分音节的，应把它分段分析，而且实际运用中的数字信号处理的FFT的点数是有限的，一般只能达到千点。用傅里叶反变换IFFT，从频域恢复信号。画出频谱图和语音波形图。 -Observing real-time analog signal (voice) of the spectrum collected with the audio devices section of
