Volumetric (3D) is already built into the notion of an image. Field3D is an example where 3D data is stored as a volume. Believe it or not, TIFF can also do this and our plugin supports it, though I don't think I've ever seen a 3D TIFF in the wild.
Different modalities (for example, MRI and CT data in the same file) should be represented as subimages, although if they were already registered and isomorphic for pixel layout, then you could do multiple modalities as one subimage but just lots of data channels. Time series should probably best be done as separate "subimages," and examples where we already do this are GIF and the ffmpeg plugin that handles movie files. > On Jul 21, 2015, at 3:02 PM, Peter Black <[email protected]> wrote: > > Hi Ghislain, > > As far as I know, the 'temporal series of images' support is limited to the > concept of 'subimages' - i.e. a file can be a container for multiple > subimages or parts - EXR uses this concept extensively, and I believe there > is/is going to be some support for an FFMPEG reader/writer which would imply > temporal series of images.
