Create Project Agnostic DICOM

Note

Users with access to Study0 are allowed to create a project agnostic copy of clinical DICOM study.

Task Description

You want to use data that are stored in the clinical PACS system use for research.

Therefore:

  • you need to select the data that are necessary

  • trigger the staging step

  • review the transfered and pseudonymized data

Prerequisits

  • your site is fully integrated in the RPB Infrastructure (otherwise see “Uploadclient”)

  • you have permissions to query the hospital PACS system

  • you have access to “Study0” in RadPlanBio

Tasks

  1. Preparation

  2. Select the patient

  3. Extend the patient table item to see the DICOM studies

  4. Navigate to “Edit”

  5. Select and stage the DICOM series

  6. Verify that staging is finished

Preparation

It is important to verify that “Study0” is active to get access to the patients of the hospital system. If you are in a different Study read here how to change that.

In the menu, navigate to “PACS - medical imaging” -> “DICOM Lookup”.

Select the Patient

There are some options to find the patient.

“Select One” is a combobox that allows to limit the items by entering search terms. It will search for the entered character combinations in the PID or StudySubjectID. The combobox shows up to 10 items. Clicking on an item selects the patient.

“Bulk Search” is intended for the case that you have a comma separated list of identifiers (like: “DummmyId01, DummyId02”) that you just paste into the text box. Patients that match will be presented in the table. It would also work with parts of the ids as searchterm, like “yId01,yId02”.

Extend the patient table item to see the DICOM studies

All patients that are selected by the different search options are presented in the main table. The arrow (1) in the first column allows to extend the item. The extended view shows the DICOM data organized as DICOM studies. The “pseudonymize” column (2) shows if at least some of the DICOM data is already staged. If there is a “No” then you need definitely to stage DICOM data. A “Yes” just means that there are some DICOM data already staged.

In that case, you could still open the dialog and verify on DICOM series level that all data is staged.

Select and stage the DICOM series

The “Edit selected DICOM Study” facilitates the selection of relevant DICOM series with two different views. The Table View just presents all DICOM series in paginated table. The RT View reconstructs the relation between radio therapie specifc DICOM series in a tree. In both cases, it is important to be precise in the selection 1.

Table View

The table view shows all DICOM series that are available. It is a good choice to select single series or to stage non-radiotherapie DICOM data.

RT View

The RT View is build for readiotherapie related DICOM data. Only DICOM series with radiotherapie related modalities are shown there.

It will evaluate the relations between the series and visualize it as a tree. That makes it easier to pick the DICOM data that are of interest.

Selecting the parent will trigger that the children are selected as well.

You still need to check want is relevant. In the next example, two plans are in the clinical system. Just one is approved and needs to be staged 1.

The hospital system is organized to reflect the whole individual threatment of the specific patient in all details. A research would focus on specific aspect of the threatment of a cohort of patients. Selecting the relevant data is very important to facilitate that reviewers can reproduce the search result.
