after "gulp build", I copied dist folder to my server's public directory, from where I can open the index.html in a Chrome browser.
For this build, there are two options: either load from computer or URL.
I have about 44 DCM files, from which med3web can construct 3D vision if I load them from computer.
When I tried to load them from URL (http://127.0.0.1:8000/files), I got the following errors:

GET http://127.0.0.1:8000/files/file_list.txt 404 (Not Found)
Loaded file list. 48 files will be loaded. 1st file in list is =
GET http://127.0.0.1:8000/files/%3C!DOCTYPE%20html%3E 404 (Not Found)
...
main.js:1134 Loading ratio = 0
main.js:911 DICM header NOT found
main.js:1134 Error load dicom folder
...

What are the requirements if I want to load DICOM files in a URL folder? Where can I find user manual?

I want to set dicom files url. Let me know the way i can achieve it.

My EMR images are stored, as exported by a PACS server, with the following structure:

If I drag the DICOMDIR file into DicomParser's example I see it's correctly decoded:

So I must be missing a step here. Am I supposed to encapsulate the whole contents of the emr_files folder into a ktx file?

When I try to load compressed dcm files, I get the error message "Compressed image formats read is not supported" on the screen and "Wrong image pixels size. Readed 331506, but expected 913152" in the console. I think it's normal for now. Will support of the compressed dcm files be added in the future?

Everyone thinks and expresses thoughts differently, so, please, add ISSUE_TEMPLATE.md to the project in order to attract open source contributions activities

How do i integrate it with my existing organization's app?
My organization is planning to add a dicom viewer feature to their existing react app, how do i integrate this app into our app. Since it's a standalone app, and not available as an npm package, how do i achieve this?

What are the points i need to look up when doing this?
Since i have never worked on open source app, and it's integration with existing app. What things do i need to look up for like in terms of dependencies, components, routing, global state management, etc?

I want to call med3web page (index.html) from another webpage with a URL link; so when med3web page is onloaded, it is automatically going to load dicom files pointed by URL.
How to achieve that?

I tried to follow before closed issue, but I didn't fix this problem yet, please help me.
Thanks.

Issue: Currently It accepts only direct ended url (.dcm files).
I want to integrate it to DCM4CHEE server where there's no direct ended url. It's in this format: http://103.11.152.52:8080/dcm4chee-arc/aets/DCM4CHEE/wado?requestType=WADO&studyUID=1.3.6.1.4.1.5962.1.1.0.0.0.1194732126.13032.0.1&seriesUID=1.3.6.1.4.1.5962.1.1.0.0.0.1194732126.13032.0.2&objectUID=1.3.6.1.4.1.5962.1.1.0.0.0.1194732126.13032.0.3&contentType=application/dicom. Even if i remove the existing regex check for the url, it says "No Files provided"

**Solution: Make it accept urls of above type **
The url from backend may be in below formats:
Format 1: http://103.11.152.52:8080/dcm4chee-arc/aets/DCM4CHEE/wado?requestType=WADO&studyUID=1.3.6.1.4.1.5962.1.1.0.0.0.1194732126.13032.0.1&seriesUID=1.3.6.1.4.1.5962.1.1.0.0.0.1194732126.13032.0.2&objectUID=1.3.6.1.4.1.5962.1.1.0.0.0.1194732126.13032.0.3&contentType=application/dicom
Format 2: https://d33do7qe4w26qo.cloudfront.net/dicomweb/studies/2.16.840.1.114362.1.11972228.22789312658.616067305.306.2/series/2.16.840.1.114362.1.11972228.22789312658.616067305.306.3/instances/2.16.840.1.114362.1.11972228.22789312658.616067306.446.301/frames/1

How to use these urls as input? After removing the regex check, it says "No file provided" for both these urls.

If its a series of dicom images, how to accept that as a url.
If I had multiple images in my system then, i can use "Open from device" and select all dicom files and I can see all the images. How to do the same in URL format? Currently it accepts singe file url, i guess.

Hi
Thank you for your wonderful project.
I`m interested in MPR in this project and going to build individual project that only do the MPR with file or folder input.
Could you let me know some keyword such as which loader it is using or which files are for MPR?
Regards,

There is not enough tool for arbitrary drawing on images (work as Paint). Is it possible to enable this feature?

Please see Jira.

Looking through CONTRIBUTING.md I came across a couple of spots where the wording could be improved.
Namely:

1. Instead of making a concrete list of people in the Contributing policy document, I'd suggest to create a separate file (i.e. MAINTAINERS or something) and list the maintainers in it. Then simply refer to that list from here.

Please don't report sensitive / security issues via public channels, try to contact maintainers privately first (e.g. at Vladislav Shubnikov or Mariia Verdina).

2. This sounds pretty abrupt. You don't want 3rd party contributors to feel like they are beggars. Instead, consider explaining how to decisions are made on the roadmap and about new feature development. Perhaps, something like a voting process (https://www.apache.org/foundation/voting.html but just concern yourself with 'Code modifications' part of it, for now) would be a good idea once the community reaches certain size.

Please make sure maintainers are expecting your changes and will consider merging them into master. If the changes do not fit the project roadmap, it might unfortunately happen that you have wasted your time.

3. This will require a constant effort to add conmmiters' SSH keys to the repositories. Besides, we are keeping these repos in the GH's EPAM organization which could increase the overhead on organization admins. I'd suggest to reconsider this point. PRs are tightly integrated with GH's review process and issue tracking - if you use GH as your main development facility why not to use all of it?
   We will not use pull requests in our everyday life

4. "Coding standards" section hardly belong to the contributing policy document. Consider it moving elsewhere. Looks like you already have CODINGSTD.md document.

5. Same goes for the tools and framework requirements. Something like DEVNOTES would better fit.

Describe the bug

Regardless of whether I use Windows or macOS, the demo web page appears blank. The Chrome Browser developer tools console window reports:

Failed to load resource: net::ERR_HTTP2_PROTOCOL_ERROR

Regardless of whether I use Windows or macOS, the command npm install listed in the README.md generates a long string of errors, and the subsequent npm run start fails. An example output on macOS:

Dear Vladislav Shubnikov!
I am here again,
I can't display 3D model on iphone safari@google chrome
Is it impossible problem?
Thanks again !

When i try to run npm install or npm run start I get a bunch of errors and warings. Similar to this case #126

Also in the demo aviable in this repo I cant load a .dcm file

Right from the top you can see Debuuging. Please run spell-checker to make sure text documents don't have typos.

I want to build react-js project
I tried to follow readme.md
but I can't build and have some errors
Please help me to build this project.
Thanks!

Describe the bug
i have the error when open dcm files multiframe (only one .dcm file)
this happens with local or remote files

Error read Dicom via Diakon parser

My problem is that I have too many files on the server and I'm looking to get only some specific files based on the user demand.

When I was having only it was working bit now I think that he's loading all the data, so he can't handle them and he crashes.
Any help please ? And thank you in advance

Hello,
I'm trying a NIFTI model in the online demo application and it loads without an issue, but when I load it locally it gives me an error as if it has a 'WRONG HEADER DATA TYPE'. Are the two applications not on the same version ?

Now the default mode is 2d,but I want 3d mode.What should I do?

Hello! I'd like to integrate your tool as a package for datagrok.ai platform (datagrok-ai/public#46), but if I understand correctly currently it is a standalone web app that cannot be used as an external library. Please, let me know how I can use med3web as an external library to read and view MRI files or if it's not currently possible, is it planned to make med3web to work as an external library?

I have the newest Windows 10 ( april/23/2019) and the example page
https://med3web.opensource.epam.com/ found at https://lifescience.opensource.epam.com/mri/ does not load the images and keeps frozen.

It works fine on Chrome.

Is there any compatibility with these browsers, specially Edge?

I want to append dcm files to current viewer when I select another files, is it possible ?

A very common type .dcm file that works well with pretty standard planmeca_romexis_viewer can't be uploaded here. It says: File Read Error Compressed image formats read is not supported.
If it is needed I can give you the file, show you how it is opened and viewed with romexis_viewer and etc.
Communication can be done in English or Ukrainian.
I'm experienced in C# and some vanilla JS.

I tried med3web. When I attempt to load NIfTI images (File/OpenFromComputer) that work fine with MRIcroGL, FSLeyes, SPM, etc, I get the error "Wrong header data type". Examples are the reference images in the "Ref" folder of dcm_qa.

When I choose File/SaveAsNifti a NIfTI file is stored, but when I attempt to view it with popular tools (MRIcroGL, FSLeyes, SPM, etc), the slices are wrapped in the left-right direction (perhaps the file writing ignored the 352 byte header offset).

I hope to display 3d model of jpeg lossless or lossy

test issue

Hey cab we build this like that we can see all 3 axis (axial, coronal, and sagittal) at same screen and have separate slider for every view.
This feature will make analysis of view easy.

I tried to open the web page which shows the demo live.
But it doesn't work.

Hi,

I am interested in using your work but I can't find documentation for actually building, running and serving the application. My use case would be to share an interactive visualization with collaborators without needing to send them a file directly. Is there a simple npm command to install and run an instance?

Thank you.

Is your feature request related to a problem? Please describe.

I'm always frustrated when I see the progress bar for too long when the application calculates filters

Describe the solution you'd like
I'd like all filter calculations be more performative.
Floating point calculations are not so good in Javascript. Further investigation is needed.

Describe alternatives you've considered
Maybe it is good to show filter appliance on the image (iteratively apply calculations while they are finished)
Maybe WebWorkers are good for that

Additional context

Sorry for interrupting you !

I can't run this project on MacOs Safari.

Latest LTS and gulp3 don't play well together.

I forked and 'fixed' this via: https://stackoverflow.com/a/58394828 but it's not a solution. You should update to gulp4
