[Bug] Stack Segmention Error

[zhoualibaba]

Describe the Bug

I encounter this issue when using Segmentation Tool (labelmap) in the stack viewport. After drawing a ROI at only one specific slice, the ROI would exist at all slices.

I tried 'csToolsSegmentation. state. getCurrentLabelmapiImageIdForViewport' (activeViewportId, 'MY_SGMENTION-ID') and found that function did not change when moving to next slice using StackScrollTool.

I think the reason is that when I changed the image slice, the 'segmentationImageId(derived:9a66f6a5-5411-42d0-b654-9f4a77c133d6)' did not change.

I would like to know if I can change the 'segmentationImageId' myself.

I created an anonymous data for debugging purposes.
sub_with_pid_c.zip

I think the stack viewport may not support certain XA modality data.

Steps to Reproduce

1.use wadouri load this data
2.use BrushTool or RectangleScissorsTool
3.use StackScrollTool

This is probably an issue with the metadata, likely all the frames have the same imagePositionPatient. Is this multiframe data?

[zhoualibaba]

@sedghi Yse, this is multiframe data,but there is no imagePositionPatient tag in the metadata.

Most XA modality data does not have this tag. Perhaps Cornerstone think that metadata contains the same imagePositionPatient.
I tried CT data with imagePositionPatient tag in STACK(wadouri) viewport,it works well. I think you are right. So i want to know is there any way to solve this problem .I think it is important for STACK viewport.

I also find that if the metadata contains ImageOrientationPatient tag, the segmentationTool does not work, as reported at [Bug] Stack Labelmap Segmentation error #1591 .

I would like to know if I can change the 'segmentationImageId' I am using myself.Like viewport.setImageIdIndex(6).

I cant really replicate this in latest ohif @sedghi

I want to know if OHIF did anything special to handle it.
I load data and use SegmentationTools like Segmentation in StackViewport.

The different is i use wadouri for loading data.
Use
await prefetchMetadataInformation(imageIds)
imageIds = convertMultiframeImageIds(imageIds)

@sedghi I tried the latest version, but the problem still exist.
I think this issue is not the same as #1591

I opened it , but since it is working (at least in OHIF) it is not a priority for us, you can look at OHIF code to see what is happening
