Under the Patients tab of the new workbench, the user has access to the list of patients associated with the specific IRB-approved RPDR project.
The main window of this tab contains five columns:
The name of the RPDR project is displayed on the top left corner (1). The interface provides the user with supplementary information, like the name of the user (here masked for reasons of data sharing) and its status (2), indicated by a colored circle at the top right corner of the panel (green indicating an active status, red indicating that some core i2b2 services on the backend are not working). As every project is allocated an amount of storage space, there is a bar indicating the proportion of space taken up by data that has been successfully requested and received from the PACS.
In all the tabs of the workbench interface - with the exception of the Image Viewer - the user has access to a panel of filtering widgets, always located on the right side of the tab. The user can show or hide this panel by clicking on the Toggle Filter(s) button. The mechanics behind filtering are simple and identical between the different tabs. There is a set of widgets corresponding to each column of the main table holding the information about the patients (in this case) or the studies (in other tabs). By appropriately selecting only the values users want to see in that column, the filter will automatically hide the rest.
There are three types of filter widgets in the new mi2b2 workbench.
When the user has performed the desired filtering procedures on the available patient information, the next step is to request the Radiology information related to this cohort using the DICOM CFIND directive in order to establish a connection with the PACS. The user simply clicks on the Get Image Study Information for Selected Patients button, located at the bottom of the main panel (3). Then, the workbench automatically switches to the next tab: Studies.
The last section of each page of this online guide provides the reader with an exemplary workflow he or she would follow when using the particular Tab of the mi2b2 client for RPDR. The first of those case studies, dedicated to the Patients tab, walks the reader from the beginning of the procedure (logging-in to the client) to the point of selecting studies and requesting detailed data for them.
