--- sidebar_position: 3 sidebar_label: URL --- # URL You can modify the URL at any state of the app to get the desired result. Here are different part of the APP that you can modify: ## WorkList The WorkList can be modified by adding the following query parameters: ### PatientName The patient name can be modified by adding the `PatientName` query parameter. ```js /?patientName=myQuery ``` ### MRN The MRN can be modified by adding the `MRN` query parameter. ```js /?mrn=myQuery ``` ### Description The description can be modified by adding the `Description` query parameter. ```js /?description=myQuery ``` ### Modality The modality can be modified by adding the `modalities` query parameter. ```js /?modalities=MG ``` ### Accession Number The accession number can be modified by adding the `accession` query parameter. ```js /?accession=myQuery ``` ### DataSources If you happen to have multiple data sources configured, you can filter the WorkList by adding the `dataSources` query parameter. ```js /?dataSources=orthanc ``` Note1: You should pass the `sourceName` of the data source in the configuration file (not the friendly name nor the name) Note2: Make sure that the configuration file you are using actually includes that data source. You cannot use a data source from another configuration file. :::tip You can add `sortBy` and `sortDirection` query parameters to sort the WorkList ```js /?patientName=myquery&sortBy=studyDate&sortDirection=ascending ``` ::: ## Viewer The Viewer can be modified by adding the following query parameters: ### Mode As you have seen before, the Viewer can be configured to be in different modes. Each mode registers their `id` in the URL. For instance ```js /viewer?StudyInstanceUIDs=1.3.6.1.4.1.14519.5.2.1.7009.2403.871108593056125491804754960339 ``` will open the viewer in the basic (longitudinal) mode with the StudyInstanceUID 1.3.6.1.4.1.14519.5.2.1.7009.2403.871108593056125491804754960339. And if configured, the same study can be opened in the `tmtv` mode ```js /tmtv?StudyInstanceUIDs=1.3.6.1.4.1.14519.5.2.1.7009.2403.871108593056125491804754960339 ``` ### StudyInstanceUIDs You can open more than one study in the Viewer by adding the `StudyInstanceUIDs` ```js /viewer?StudyInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095722.1&StudyInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095258.1 ``` :::tip You can use this feature to open a current and prior study in the Viewer. Read more in the [Hanging Protocol Module](../platform/extensions/modules/hpModule.md#matching-on-prior-study-with-uid) section. You can also use commas to separate values. ::: ### SeriesInstanceUIDs Sometimes you need to only retrieve a specific series in a study, you can do that by providing series level QIDO query parameters in the URL such as SeriesInstanceUIDs. This does NOT work with instance or study level parameters. For example: ```js http://localhost:3000/viewer?StudyInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095438.5&SeriesInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095449.8 ``` This will only open the viewer with one series (one displaySet) loaded, and no queries made for any other series. Sometimes you need to only retrieve a subset of series in a study, you can do that by providing more than one series, separated by commas. For example: ```js http://localhost:3000/viewer?StudyInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095438.5&SeriesInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095449.8,1.3.6.1.4.1.25403.345050719074.3824.20170125095506.10 ``` This will only open the viewer with two series (two displaySets) loaded, and no queries made for any other series. ### initialSeriesInstanceUID Alternatively, sometimes you want to just open the study on a specified series, but allowing other series to be present too. This is the same behavior can be achieved by using the `initialSeriesInstanceUID` parameter. For example: ```js http://localhost:3000/viewer?StudyInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095438.5&initialSeriesInstanceUID=1.3.6.1.4.1.25403.345050719074.3824.20170125095449.8 ``` This will open all the series in the study, but the viewer will start with the series specified by the `initialSeriesInstanceUID` parameter. Note that you can combine these, if you want to load a specific set of series plus show an initial one as the first one selected, for example: ```js http://localhost:3000/viewer?StudyInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095438.5&SeriesInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095449.8,1.3.6.1.4.1.25403.345050719074.3824.20170125095506.10&initialSeriesInstanceUID=1.3.6.1.4.1.25403.345050719074.3824.20170125095506.10 ``` ### initialSopInstanceUID You can also specify the initial SOP Instance to be displayed by using the `initialSopInstanceUID` parameter. For example: ```js http://localhost:3000/viewer?StudyInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095438.5&SeriesInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095449.8&initialSopInstanceUID=1.3.6.1.4.1.25403.345050719074.3824.20170125095501.9 ``` This will open the study with the filtered series, and navigate to the slice 101 which happens to be the SOP Instance specified by the `initialSopInstanceUID` Note: again you can mix and match ```js http://localhost:3000/viewer?StudyInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095438.5&SeriesInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095449.8,1.3.6.1.4.1.25403.345050719074.3824.20170125095506.10&initialSeriesInstanceUID=1.3.6.1.4.1.25403.345050719074.3824.20170125095506.10&initialSopInstanceUID=1.3.6.1.4.1.25403.345050719074.3824.20170125095510.8 ``` You can even load the whole study and only specify the initial SOP Instance to be displayed. Although it will take more time to match, but it works as expected. ```js http://localhost:3000/viewer?StudyInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095438.5&initialSopInstanceUID=1.3.6.1.4.1.25403.345050719074.3824.20170125095510.8 ``` ### hangingProtocolId You can select the initial hanging protocol to apply by using the hangingProtocolId parameter. The selected parameter must be available in a hangingProtocolModule registration, but does not have to be active. For instance for loading a specific study in mpr mode from start you can use: ```js http://localhost:3000/viewer?StudyInstanceUIDs=1.3.6.1.4.1.25403.345050719074.3824.20170125095438.5&hangingProtocolId=@ohif/mnGrid ``` ### token Although not recommended, you can use the token param in the URL which will inject the token into the Authorization header of the request.
