[Insight-users] Re: Re: reading dicom with FrameTimeVector

[kurt]

Hi Mathieu,

Thanks!

I think the last option will do: read the 3D volume, read the time vector, find the minimum viable time span, interpolate slices. probably we will need to specify the time span. 

I will check the imaging part and get it back to you soon...

Thanks!
