Reset cornerstone before loading new image.

[hubtub2]

I have a website where I need to load the next image-stack after working on the first one (without reloading the entire page). How do I reset cornerstone including all tools.

I tried the following: cornerstoneTools.globalImageIdSpecificToolStateManager.restoreToolState({}); cornerstone.disable(element); stack = {}; cornerstone.enable(element);

Loading the next image works and the tool annotations are gone. However, the tools do not work anymore.

Readding the tools using addTool() and then calling setToolActive() does not work.

What is the prefered method to reset and reload the next image?

Transfering this issue to the cornerstone-tools repository.

@hubtub2, most toolState / annotations are specific to an imageId. If you're viewing a new stack of different imageIds, you likely don't need to clear tool state. I also believe there's clearToolState if you need something more granular.

When you disable an element, cornerstone-tools should tear down all of it's tool additions. enable should give you a clean slate you can addTool and setToolActive before. If you're encountering issues and can provide a reproduction, this may be worth a bug fix PR. Lastly, if you want addTool and setToolActive to persist across newly enabled elements, you may want to look into the globalToolSyncEnabled option for cornerstone-tools.

Chances are, you're doing more than you need to. You can likely swap out the image stack and call it a day. Depending on the kind of application you're building, you can see how we handle lifecycle events like this in our react-cornerstone-viewport, which includes an example for swapping stacks.

It seems like you're asking how to reset cornerstone before loading a new image stack without reloading the entire page. The suggested method for resetting cornerstone and its tools is to disable the element, which should tear down all the tool additions, and then enable it again for a clean slate. If you encounter any issues, you can try using the clearToolState function, which removes all toolState from the toolStateManager corresponding to the toolName and element.
