Is it possible to interactively annotate slices of a volume in dash-slicer?

almarklein commented 2 years ago

Yes, see for example https://dash.gallery/dash-covid-xray/. Dash-slicer has support for masks, so you can visualize the data as well as an overlay. The interaction (how mouse clicks result in changes to the mask) are for you to implement.

Hi Almar, thanks for the link "https://dash.gallery/dash-covid-xray/". In the app, if I draw annotation then it does not change with slide change (images attached). I need to annotate different slices with different shapes as 3D slicer supports. 1

I am new to Dash-Slicer, it would be very helpful if you can provide some code on handling such annotation.

That's because of how that app works. It is not per-slice, but you select a rough volume. If you are writing an app yourself in which you want per-slice annotations, you need to eg. reset the drawing tool.
