The CT metadata selection can bind the SEG to the wrong series and the wrong slices.
Two problems combine here:
- Line 288 selects the first display set whose
ModalityisCT. The segmentation may reference a different CT series in the same study. The code does not compareSeriesInstanceUIDwith the referenced series. - Line 308 indexes
originalDisplaySet.images[sliceIndex]by array position. This assumesimageshas the same order and length asfilteredReferencedImageIds. Display sets are sorted by the customization service, so the orders can differ. A mismatch writesImagePositionPatient,PixelSpacing, andSeriesInstanceUIDfrom the wrong slice into the exported SEG.
Resolve the CT instance by identity instead of by index. Use the SOPInstanceUID you already extract from referencedImageId and look up the matching instance. Also select the display set whose SeriesInstanceUID matches the referenced series.
🐛 Proposed fix: match by SOPInstanceUID
- referencedImages = filteredReferencedImageIds.map((referencedImageId, sliceIndex) => {
+ const instancesBySOPInstanceUID = new Map(
+ (originalDisplaySet?.images ?? []).map(image => [image.SOPInstanceUID, image])
+ );
+
+ referencedImages = filteredReferencedImageIds.map((referencedImageId, sliceIndex) => {
const referencedImage = cache.getImage(referencedImageId);
...

- const originalImage = originalDisplaySet.images[sliceIndex];

+ ? instancesBySOPInstanceUID.get(sopInstanceUID)

+ if (originalImage) {Note also that Lines 264, 311, and 334 assign to referencedImage.data on the object returned by cache.getImage. That object is shared with the viewport. Copy the image reference before you overwrite data.

Remove the hardcoded http://localhost:8082 export call.
This block sends the stored SEG to a fixed development host from application code. Several concrete problems:
- The host and port are hardcoded. In any deployment other than the developer machine, this request fails, and the failure is only logged. Read the base URL from the data source configuration or the app config.
folderIddefaults to an empty string (Line 610). The URL then becomes/api/dicom-folders//files/<name>/export, which is not the intended route.folderIdandfileNameare interpolated into the path withoutencodeURIComponent.fileNamederives from the user-supplied segmentation label, so a label containing/,?, or#changes the request path.- The
fetchcall has no timeout and noAbortSignal.storeSegmentationawaits it, so an unresponsive host blocks the store flow. - The comment and the log text state a download fallback, but no fallback runs. The catch block only logs.
caseId(Line 609) is assigned and never used.

The Cornerstone event listener never attaches.
Line 112 reads window.cornerstone?.eventTarget. Cornerstone3D does not publish itself on window in an OHIF build. eventTarget is therefore undefined, the if (eventTarget) branch is skipped, and STACK_NEW_IMAGE is never observed. currentFrameIndex stays at 0, so the overlay always draws frame 0 regardless of the displayed slice.
Line 2 already imports from @cornerstonejs/core. Import eventTarget from the same module.

The overlay canvas does not follow the viewport pan and zoom.
The canvas backing store is the mask size, and CSS stretches it to 100% of the parent. The mask therefore maps to the whole viewport rectangle. The Cornerstone image below is positioned by camera pan, zoom, and aspect fit. The mask is misaligned as soon as the user zooms, pans, or the viewport aspect ratio is not square. A misaligned segmentation overlay is clinically misleading.
Project the mask through the viewport coordinate transform (for example viewport.worldToCanvas on the image corners), or render the mask as a Cornerstone labelmap so the existing pipeline handles the geometry.

Line 336 dereferences undefined and throws when ReferencedSeriesSequence is absent.
The branch on Line 305 handles a missing referencedSeriesSequence and continues. Execution then reaches Line 335. instance.ReferencedSeriesSequence is undefined, so the array is [undefined]. The callback spreads undefined without error, but Line 337 evaluates ref['00001114'] on undefined. That raises TypeError: Cannot read properties of undefined. The SEG display set is never created, and the failure occurs on the exact path this change was added to support.
Line 315 has a second defect: it returns undefined while the success path returns [displaySet]. Callers that iterate the result then fail. Return an empty array.

Two competing SEG overlays are mounted at the same time and share one event name with incompatible payloads. OHIFCornerstoneSEGViewport renders CustomSegmentationOverlay, and the OHIFCornerstoneViewport it wraps also renders SimpleSEGOverlay. Both listen on window for SEG_LOADED, but CustomSegmentationOverlay reads event.detail.segDisplaySetUID while SimpleSEGOverlay reads event.detail.caseId and event.detail.fileName. The producer in extensions/cornerstone-dicom-seg/src/commandsModule.ts emits only the first shape. Therefore SimpleSEGOverlay silently ignores that event, and each overlay can draw its own mask with its own guessed geometry, producing double or conflicting overlays. Keep one implementation and one typed event contract.

Cornerstone3D 5.6.8 IViewport worldToCanvas CAMERA_MODIFIED getCanvasRectangle API
💡 Result:
In Cornerstone3D version 5.6.8, the following APIs and events are relevant to coordinate transformations, camera updates, and viewport layout: 1. IViewport.worldToCanvas The worldToCanvas method is a core function on viewport instances (such as StackViewport and VolumeViewport) used to transform 3D world coordinates into 2D canvas coordinates [1][2]. It is frequently used by tools to map annotation or segmentation positions from the image data space to the screen space [1]. 2. CAMERA_MODIFIED Event The CAMERA_MODIFIED event (defined as Enums.Events.CAMERA_MODIFIED or 'CORNERSTONE_CAMERA_MODIFIED') triggers on the viewport's HTML element whenever the camera properties—such as position, focal point, or zoom—are updated [3][4]. This event is crucial for synchronizing views or updating tool overlays [5]. It provides a CameraModifiedEventDetail object, which contains the current and previous camera states [6]. 3. getCanvasRectangle There is no standard, direct API named getCanvasRectangle on the viewport or core rendering engine in Cornerstone3D 5.6.8. To obtain the dimensions or position of a viewport's canvas, developers typically use standard DOM methods on the viewport element, such as element.getBoundingClientRect, or access the canvas directly via the RenderingEngine [7][8]. For example, the internal canvas dimensions are often derived from the viewport element's size multiplied by the device pixel ratio [7]. If you are looking to calculate coordinate bounds or perform viewport-specific layout logic, it is recommended to use element.getBoundingClientRect for the viewport's screen space or to access the rendering engine's internal canvas directly through the viewport instance [7].

site:github.com/cornerstonejs/cornerstone3D "class StackViewport" "worldToCanvas" "getCanvasRectangle"
💡 Result:
In Cornerstone3D, StackViewport is a class that inherits from the base Viewport class [1]. The methods worldToCanvas and getCanvasRectangle are key components for coordinate transformation and layout management. worldToCanvas The worldToCanvas method is defined on the Viewport class (and thus available on StackViewport) [1]. It takes a 3D coordinate in world space (Point3) and projects it onto the viewport's 2D canvas, returning a Point2 [2][3]. This method is commonly used in annotation tools to map world-space annotation points to their corresponding positions on the HTML canvas for rendering [4][5]. getCanvasRectangle There is no direct method named getCanvasRectangle on the StackViewport or Viewport class in the public API of Cornerstone3D [2][1][3]. However, viewports provide properties and methods to determine their size and position on the canvas. Viewport instances have properties such as sWidth and sHeight, and the RenderingEngine provides a resize method to update the canvas dimensions to match the DOM container [1][6][7]. When developers need to calculate bounding boxes or areas on the canvas (such as for annotations), they typically use worldToCanvas to transform world-space bounds (e.g., topLeft, bottomRight) into canvas coordinates [4][5]. Key Considerations 1. Accuracy: The accuracy of worldToCanvas depends on the viewport having correct and updated canvas dimensions. If the container size changes (e.g., via browser zoom or window resize) and RenderingEngine.resize is not called, coordinate transformations will become inaccurate [8][7]. 2. Alternative Mappings: If you require mappings between world coordinates and the image pixel space (rather than the canvas display space), utilities like worldToImageCoords are available in the Cornerstone3D utilities namespace [9].

Use the viewport camera to position the SEG mask.
@cornerstonejs/core@5.6.8 exposes worldToCanvas and CAMERA_MODIFIED, but not getCanvasRectangle. The fallback therefore assumes a centered square. This is incorrect for non-square images and for pan or zoom operations, so the mask can cover the wrong anatomy. Map the image or SEG world-plane corners with viewport.worldToCanvas and redraw on CAMERA_MODIFIED, with cleanup.

The 512x512 temporary canvas ignores the actual SEG dimensions.
Lines 163-164 and Line 170 hardcode 512. Lines 237-238 read the real Rows and Columns, and Line 172 computes frameSize from them. When the SEG is not 512x512, the code writes rows * columns pixels into a 512x512 ImageData, so the mask is skewed or truncated.
Two related defects compound this:
- Lines 278-279 store
rowsandcolumnsexactly asdataSet.uint16returned them. If either tag is missing, the value isundefined,frameSizeon Line 172 becomesNaN, and the render loop body never runs. Line 249 applies a512fallback, but only for the slice-range scan, so the two code paths disagree. safeSliceIndexon Line 174 clamps withMath.min, but a negativenumFramesorsliceIndexis not clamped at the lower bound.

dcmjs 0.52.0 datasetToDict DicomDict source this.dict
💡 Result:
In dcmjs (including version 0.52.0), the pattern you described involves manipulating the internal dictionary representation of a DICOM object. The property this.dict refers to the internal DICOM dictionary object held by an instance of dcmjs.data.DicomDict (or a similar construct), which stores tags in a specific format where keys are DICOM tag strings (e.g., '00100010') and values contain the Value Representation (VR) and the tag's Value [1][2]. Here is the breakdown of how this is typically used: 1. Initialization: You can create a new DicomDict instance, often by passing an object to the constructor or by reading an existing file [2]. const dicomDict = new dcmjs.data.DicomDict({}); 2. Accessing and Modifying this.dict: The dicomDict object contains a dict property. This property holds the raw DICOM data structure. You can add, remove, or modify tags directly within this object [1][2]. // Example of setting a tag directly in the internal dictionary dicomDict.dict['00100010'] = { vr: 'PN', Value: ['Doe^John'] }; 3. Naturalizing/Denaturalizing: Because the raw dict structure is verbose and difficult to work with, dcmjs provides naturalizeDataset and denaturalizeDataset utilities. These convert the raw dict into a more programmer-friendly JSON-like object (naturalized) and back into the raw dictionary format [3][2]. // Naturalize for easier editing const dataset = dcmjs.data.DicomMetaDictionary.naturalizeDataset(dicomDict.dict); dataset.PatientName = "Doe^John"; // Denaturalize back to the raw format required by dcmjs dicomDict.dict = dcmjs.data.DicomMetaDictionary.denaturalizeDataset(dataset); 4. Writing: Once the internal dict has been updated and denaturalized (if necessary), you use the write() method on the DicomDict instance to generate a DICOM Part 10 conformant ArrayBuffer [1][4][2]. const updatedDicomArrayBuffer = dicomDict.write; It is important to note that when manually manipulating this.dict or the raw dataset, you are responsible for ensuring that all required DICOM tags are present and correctly formatted according to the VR specified, as dcmjs does not automatically validate the entire dataset structure [2].

Repair dicomDict.dict with standard DICOM tags.
datasetToDict stores dataset elements in dicomDict.dict, and write() serializes only that map. The tag checks and assignments to dicomDict[...] at Lines 135-180 therefore do not affect the output. Use 00081115 for ReferencedSeriesSequence and 0008114A for ReferencedInstanceSequence. Normalize ReferencedSeriesSequence to an array and guard ReferencedInstanceSequence before calling .map. Move the repair before datasetToDict, or write the corrected elements through dicomDict.dict.

Remove the adapter workaround and fix SEG metadata
_loadSegments returns at line 778 before createFromDicomSegImageId runs, so the registered patch is currently unreachable.
If the original loader is restored, segmentIndex = 1 throws TypeError: Assignment to constant variable. The warning also contains corrupted characters. Do not default an unknown segment to 1; ensure the export path supplies the segment metadata required by getSegmentIndex, then remove the patch.
