Troubleshooting and support

Why is a button disabled?

Select a series and wait for import, then check its modality and format. MPR/3D require regular volumes; 4D requires valid CT phase groups. MR 4D playback, fusion and CT analysis tools remain unavailable; PET montage is unavailable. Hover over an entry for its reason, and see Supported images and formats.

ROI versus VOI

Ordinary rectangle / ellipse ROIs provide 2D slice statistics. MPR segmentation and VOI provide 3D statistics with depth. 3D cropping changes display only. PET MIP is a projection and is not used to draw 3D regions.

Where are my results?

Click the original tab if it is still open. If you closed it, choose Workspace → Reopen closed tab, then check the slice, sampling grid and region visibility. Opening the series from the list starts an independent reading tab.

Workspace saves and automatic recovery copies include results from closed tabs; drafts and undo history are not saved. Automatic recovery does not replace manual saving: changes after the latest save or recovery copy may be lost. Workspaces do not contain original image pixels, so keep the source files.

Not yet supported

SR import, RTSTRUCT exchange, probabilistic or LABELMAP SEG, contour interpolation and segmentation surface generation are not supported. Paint/erase refinement, binary SEG and NRRD exchange, SR export and single-slice freeform conversion are supported. Common color 2D and ordinary decodable color multiframe objects are supported; video codecs, color MPR/3D and ultrasound region calibration are not. Enhanced PET, Mosaic and MR quantitative analysis remain unavailable; grayscale Enhanced MR is supported. Irregular volumes are outside regular-grid reconstruction.

Large images load slowly or memory is low

Let the current task finish and avoid opening several MPR/3D tabs at once; try 2D first. If memory is still low, save the workspace, close unused tabs, and retry. Import large collections in smaller batches.

Cancelling loading does not delete the source images. If undo history cannot be recorded, free resources and click Retry recording. Unavailable undo does not mean your work has been saved.

AI segmentation fails or results are missing

On failure, read the reason in the organ-selection dialog, then open Details for the log. Check the environment, model, device, or memory as indicated, and retry after addressing the cause. Failed or cancelled runs do not import partial results.

If the run has finished but results are not visible, return to the target tab and phase used for the run, and finish any active edit so import can proceed. After successful import, the dialog closes. Check organs, visibility, and colors in the segmentation list. Organs not detected are reported separately.
