Security Error when loading xray dicom images

[meisterpeeps]

I am trying to load dicom images and some of them, particularly x-rays are giving me an error. I can successfully load other dicom images, but not the x-rays with the dicom wado loader. I can also load the x-rays using MicroDicom viewer. The error I get:

Security Error: Content at http://localhost:3000/dicom may not load data from blob:http://localhost:3000/610.bundle.min.worker.js.

SecurityError: WorkerGlobalScope.importScripts: Failed to load worker script at "blob:http://localhost:3000/610.bundle.min.worker.js

Is that error meaningful to anyone?

Hmm that's quite strange. Could you post a de-identified copy of one of the images?

I had the same issue, I specified the full paths to the 610.bundle.min.worker.js and 888.bundle.min.worker.js files with:

config = {
	webWorkerTaskPaths: [
		folder + "/610.bundle.min.worker.js",
		folder + "/888.bundle.min.worker.js"
	]
};
cornerstoneWADOImageLoader.webWorkerManager.initialize(config);

Where folder contains the directory (including host) where the files are stored.

I haven't seen the security error since reverting to an older version and then switching to the newest version of wadoImageLoader. Other than that, I didn't change anything. However, some of my images do not render at all still and I also have a problem with some images properly sharpening. I'm using the sharpening code from the custom webworker example: https://rawgit.com/cornerstonejs/cornerstoneWADOImageLoader/master/examples/customWebWorkerTask/index.html

When using the following image, the image gets cut in half rather than sharpening.
https://github.com/meisterpeeps/dicomTest/blob/main/test0.dcm?raw=true

Also, the following image doesn't render at all. It receives a "dicomParser.readPart10Header: DICM prefix not found at location 132 - this is not a valid DICOM P10 file." It can load in the MicroDicom viewer, but cornerstone doesn't load it. The error seems more understandable -- something to do with a header in the file?

This second part... actually not a problem. I think I must have had a typo, because it works for me now. That test2.dcm should just be 2.dcm.

The sharpening issue seems legit though.

[meisterpeeps]

... Figured out the source of the sharpening issue... the example code converts the arraybuffer into an int16typedarray and it seems it needs an uint8clampedarray for arraybuffers that contain values between 0 and 255.

Where did you find these 610 and 888 js files in the first place? Is that something I can download and then drop into a folder on my server? I'm fairly new to this and running into the same error when loading PW ultrasounds vs standard 2D which load without issue.

"7ca8aa43-6c62-411c-a8bb-6ebb060a4897:1 Uncaught (in promise) DOMException: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'blob:http://deidentified-server.com/610.bundle.min.worker.js' failed to load."

Either:

• https://unpkg.com/browse/[email protected]/dist/
• https://www.npmjs.com/package/cornerstone-wado-image-loader

Either:

• https://unpkg.com/browse/[email protected]/dist/
• https://www.npmjs.com/package/cornerstone-wado-image-loader

I'm not sure how to use the npmjs link, but what works for me is the unpkg link after removing /browse - otherwise I get mime type errors.

• https://unpkg.com/[email protected]/dist (note that I changed the version to 4.0.4)
