Allow adding slices with different orientation in the same serie

[MehmetStead]

Is this possible, or is there at least a way to achieve this with a workaround, many other professional dicom viewers allow images with different orientation in the same serie. However, the component has an explicit check and throws an error for other orientations.

appendSlice(rhs) {
    // check input
    if (rhs === null) {
      throw new Error('Cannot append null slice');
    }
    const rhsSize = rhs.getGeometry().getSize();
    let size = this.#geometry.getSize();
    if (rhsSize.get(2) !== 1) {
      throw new Error('Cannot append more than one slice');
    }
    if (size.get(0) !== rhsSize.get(0)) {
      throw new Error('Cannot append a slice with different number of columns');
    }
    if (size.get(1) !== rhsSize.get(1)) {
      throw new Error('Cannot append a slice with different number of rows');
    }
    if (!this.#geometry.getOrientation().equals(
      rhs.getGeometry().getOrientation(), 0.0001)) {
      throw new Error('Cannot append a slice with different orientation');
    }

I need to think about this one because if the check is removed, the created data is not a real '3D' image. Some functionalities then need to be disabled (for example MPR).

I understand, but especially for LOCALIZER images, where reference lines are drawn, here are usually images with different orientations, from different views, in the same serie. I have just looked at a professional dicom viewer today, and this was possible. Perhaps at least a way to allow it with a flag, if required, by the user. It could be set to false default. If set the true, the 3d functionalities can be disabled

@ivmartel or perhaps a 2D and 3D serie, with corresponsing functionalities enabled, disabled,

@ivmartel I'm running into this issue now as well. Another tool I've looked at handles this by separating the different orientations into sub-series that the user can toggle between. Would creating a different data set per orientation and sending some kind of event back up to the user to handle displaying that as they choose be a viable option to handle the multiple orientations in a single series problem?
