The DICOMcloud is a standalone DICOMweb server with RESTful implementation of the DICOMweb/WADO services:

  • QIDO-RS: Look up studies, series, images. Results will be limited to a maximum results. more info

  • WADO-RS: Retrieve studies, series, images, frames and metadata

  • STOW-RS: Store DICOM instances/images

  • WADO-URI: Web Access to DICOM objects

Additionally, the server implements the following RESTful services which are not part of the DICOM standard:

  • DELOW-RS: Delete DICOM instances/images

  • OHIF-Viewer: Integration service with the OHIF viewer, return OHIF formatted study information (series and instances) Click here to learn more about using the DICOMcloud server and the OHIF Viewer.


The DICOMcloud server can interface with any DICOMweb client over the current implemented features (qido-rs, wado-uri, wado-rs and stow-rs).

The DICOMcloud is a web server that can interface with any DICOMweb client over the current implemented features (qido-rs, wado-uri, wado-rs and stow-rs).

An example DICOMweb client implementation with viewer support is provided here.

The implementation is customizable by using StructureMap as a DI (Dependency Injection) framework to provide a plug-in architecture.

The main layers of the DICOMcloud:

Layer Description Project Name Nuget Link
WebAPI RESTFUL Services The webservice implementation as an ASP.NET WebAPI DICOMcloud.Wado.WebAPI NuGet Pre Release
DICOMweb Core Services The DICOMweb implementation for processing web requests and returning web responses. DICOMcloud.Wado NuGet Pre Release
DICOM Services The core DICOM code and business services that process the DICOM datasets, perform query, retrieve and store. With interfaces to classes for storage and data access. DICOMcloud NuGet Pre Release
Data Storage and Data Access The specific implementation layer that physically save the DICOM dataset media to a file system or Azure Blob and interface with Microsoft/Azure SQL database. DICOMcloud
NuGet Pre Release & NuGet Pre Release

DICOMcloud Architecture


The code is written in C# .NET Framework 4.5.2 and can be built using Visual Studio 2017 and can run on Windows machine or Azure WebApp.

The project uses MS SQL Database (Azure SQL Database compatabile) to query the DICOM information and saves the DICOM datasets to either the file system or an Azure Blob Storage.

Running the code

You will need Visual Studio 2017/2015 (can be downloaded for free here). Open the solution file DICOMcloud.sln on the root directory, if not already selected as the StartUp Project, right click on the "DICOMcloud.Wado.WebApi" project and select "Set as startup project" then run the solution by pressting F5.

Once you run the project, the DICOMweb server will run on https://localhost:44301/ and the default settings will attach an empty database to your local SQL DB server installed with Visual Studio (LocalDb)\MSSQLLocalDB and the images will be written to a directory under the "App_Data" folder.

You can change these settings from the web.config by updating the two values under the appSettings section:

 <add key="app:PacsStorageConnection" value="|DataDirectory|\App_Data\Storage\ds" />
 <add key="app:PacsDataArchieve" value="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\DB\DICOMcloud.mdf;Initial Catalog=DICOMcloud;Integrated Security=True" />

The DICOMcloud project utilizes the opensource fo-dicom DICOM library for operations on the DICOM datasets, such as reading and writing elements, compress/decompress the DICOM images, anonymization feature and many others.
