#Tauco

Provides an easy way to obtain DICOM data from the servers. For DICOM operations utilizes the Fellow Oak DICOM for .NET library.

---

##Features

• Targets .NET version 4.6 and higher
• Convenient API for basic DICOM operations (fetching patiens and related images)
• Fully asynchronous using async/await pattern
• Built-in caching
• Integrated logging
• Console application for usage outside the .NET environment
• integrated Dicom server for downloading the images

Limitations

• Only predefined attributes are loaded for DICOM objects
• Patient IDs are parsed to match czech/slovak birth numbers. If parsing fails, no ID is loaded.
• Only read-only operations are permitted

Examples

Library uses Castle Windsor for building dependency tree.

using Castle.Windsor;
using Tauco.Dicom;

var patientsProvider = container.Resolver<IPatientInfoProvider>();
var studyProvider = container.Resolver<IStudyInfoProvider>();
var seriesProvider = container.Resolver<ISeriesInfoProvider>();

Obtaining all patients

####From server

var patients = await patientProvider.GetPatients().ToListAsync();

####From cache

var patients = await patientProvider.GetPatients().LoadFromCache().ToListAsync();

###Obtaining single patient

var patient = await patientProvider.GetPatientByBirthNumberAsync("9107256444");

Note:

• Both version of birth number with and without the slash can be used.

###Downloading patient images Following code will download all patient's images to default folder (Dicom/<Patient name>/<Study UID>)

await patientProvider.DownloadImagesAsync(patient);

The path can be customized by providing optional parameter:

await patientProvider.DownloadImagesAsync(patient, (studyUid, instanceUid) =>
            {
                var path = Path.GetFullPath(@".\DICOM");
                path = Path.Combine(path, studyUid);

                if (!Directory.Exists(path))
                {
                    Directory.CreateDirectory(path);
                }

                return File.Create(Path.Combine(path, instanceUid) + ".dcm");
            });

Files can be downloaded for individual studies too:

await studyProvider.DownloadImagesAsync(study);

##Caching All server responses are cache by default. Cache files are stored in Cache/<Object type>/.... Because Dicom data usually cannot be modified, using of cache whenever possible is recommended.

Configuration

###Server Both remote and local server can be configured via the app.config file. Following app keys are expected to be present in configuration section:

<appSettings>
	<add key="CallingApplicationEntity" value="" />
	<add key="DestinationApplicationEntity" value="" />
	<add key="CalledApplicationEntity" value="" />
	<add key="RemoteAddress" value="" />
	<add key="RemotePort" value="" />
	<add key="LocalAddress" value="" />
	<add key="LocalPort" value="" />
</appSettings>

Note:

• Destination AE will be used by the remote server when downloading the images. This key has to be recognized by Dicom server together with the local address and port; otherwise downloading of files will not work.

###Logging Logging file location and verbosity can be changed in Nlog.config file shipped with source/binaries.
