Digital Imaging for Medicine in Nextcloud


It looks like urls are generated in wrong path. Could you share your config file? (You can omit your password)

What config file - Nextclouds config.php?

Yes, config.php

Fresh installation - nothing fancy in there:

$CONFIG = array (
  'instanceid' => '*',
  'passwordsalt' => '*',
  'secret' => '*',
  'trusted_domains' =>
  array (
    0 => 'nextcloud.praxis.local',
  'datadirectory' => '/data/nextcloud/data',
  'overwrite.cli.url' => 'http://nextcloud.praxis.local',
  'dbtype' => 'mysql',
  'version' => '',
  'dbname' => 'nextcloud',
  'dbhost' => 'localhost',
  'dbport' => '',
  'dbtableprefix' => 'oc_',
  'dbuser' => 'user',
  'dbpassword' => '*',
  'installed' => true,

Thanks for your answers. One more thing, could you please try to update htaccess with the following command (replace www-data with the user your web server is running under if it is different)? Also, which web server are you using, apache or nginx?

sudo -u www-data php occ maintenance:update:htaccess

Updating htaccess didn’t change anything.:cry:

Apache 2.4.25 is my web server.

I applied a fix for the URL generation in v0.0.5 Could you please give it a try with v0.0.5?

Thanks for your help!


Thank you for your help!

With v0.0.5 I get a picture, unfortunately just the first one, scrolling the levels does not work.

There are still red messages in web console.

Unfortunately, scrolling through images is not supported yet but it is in the roadmap. Also, there is an open issue about it:


besides the issue with the missing scrolling, I do find the DICOM viewer a really great extension to Nextcloud. The apps looks very clean and polished already. Very well done!

Maybe healthcare support could be expanded:


Who are the target users of this DICOM viewer?

No it is not DICOM error. At least I don’t think it is. New to Linux, web servers, and Nextcloud.

I install Nextcloud 12 snap the upgrade to Nextcloud 13 snap the test one.

Hi @leogrande,

Anyone interested in storing, viewing and sharing DICOM images with the secure cloud platform Nextcloud. That includes, but is not limit to, patients, individual radiologists, radiology technicians or health care providers who use Nextcloud for DICOM storage and collaboration.


Hello, I need you to help me install or configure the dicom viewer properly in my nextcloud 13.
Thank you.

  1. On your Nextcloud, simply navigate to Apps > Multimedia > DICOM Viewer, and enable it. that all if you don’t want to build from scratch.
  2. And if you decide to build it then first install NodeJS for JavaScript dependencies then perform step 3 to 5
  3. Run make && make source command to build source code
  4. Copy build/artifacts/source/dicomviewer into path-to-nextcloud/apps
  5. Enable the DICOM Viewer app

Thanks for the help.
