Provide a readImageDICOMArrayBufferSeries

[FezVrasta]

Our pipeline looks like the following:

1. fetch a .tar file containing several DICOM files
2. untar the DICOM files with js-untar
3. pipe each of them into a File instance
4. pass the list of Files to readImageDICOMFileSeries

It'd be extremely useful if itk-wasm exposed a function similar to readImageDICOMFileSeries but that accepts a list of ArrayBuffers, since that's what we already receive from js-untar, this way the logic would look like this:

1. fetch a .tar file containing several DICOM files
2. untar the DICOM files with js-untar
3. pass the list of ArrayBuffers to readImageDICOMArrayBufferSeries

The process that creates the "fake" File instances can take a lot of time (400ms on a ~300 DICOMs list)

Is there any technical reason that prevents this from being added?

Thanks!

Hi @FezVrasta ,

Yes, a readImageDICOMArrayBufferSeries could be created, where readImageDICOMFileSeries is refactored to call this function, similar to how readImageArrayBuffer / readImageFile works -- I'll add this.

@FezVrasta added in #482

I tested it locally and it seems to work, thanks!

Do you think you could do the same for readDICOMTags? I see a lot of calls to readAsArrayBuffer that should be unnecessary given I already have the arrayBuffers available.

@FezVrasta excellent!

Yes, will-do for readDICOMTags.
