Reverse FFT ? [message #21100] Tue, 08 August 2000 00:00

Can you do a reverse FFT in IDL and how is it implemented ?
ie. FFT provides a complex array - How do you get the original Time domain
back from the complex series.

I am trying to retrieve "k" space data back from real/imaginary MRI data. I
would like to see how time consuming this really is.

Thanks
Rich
