Overview
Search
Users can search for patients via Medical Record Numbers (MRNs), and search for studies via these patients or, alternatively, Accession Numbers (ANs). Both of these search tasks follow the same communication diagram below.

In mi2b2 client's Tab 1, users can enter a list of MRNs and search on the PACS to find the list of corresponding patients. Once the list of patients is found, users can use these patients to find a set of DICOM studies corresponding to these patients. Alternatively, if the users already have a list of ANs, they can enter them in Tab 2 and search on the PACS for these studies. Finally, after a list of studies is obtained, users can select the desired ones and request the studies to be copied to the remote cache. The request adhers to the following diagram.
Request
| Section |

The mi2b2 client sends requests to the mi2b2 server, which, in turn, asks the PACS to copy these studies into mi2b2 server's own cache. The copying of studies is done via the DICOM C-Move directive, and is executed asynchronously by the mi2b2 server. Because accessing clinically utilized PACS may impact their performance, mi2b2 is typically configured to only access these PACS during downtime (when volume of clinical use is low). As such, the time it takes to fulfill each request is highly dependent upon the mi2b2 server's configuration, PACS access policy, load, and availability. Once the studies are available in the mi2b2 cache, users can later download them onto their own local machine. |

As the transferring of studies from PACS to mi2b2 server is asynchronous, users can check the request status by asking the mi2b2 server. This is executed whenever user visits Tab 3 or click on Tab 3's "refresh" button. |

This is a screenshot of the mi2b2 client's Tab 1 at the start. - (Select an Institution) Users must first select an institution and an institution against whose PACS the search will be performed.
- (Select a Department) Once an Institution is selected, the department dropdown box becomes active. The default value is "All Departments".
- (Clear MRNs in the Text Area) Users can clear the values in the current text box by clicking on this button
- (Import MRNs from a File) Users can import MRNs stored in a text file (.txt). The MRNs must be comma- or newline- separated.
- (Scout for Patients with the MRNs in the Text Area) Click this button to execute the search. This button is only activated when there are MRNs in the text area, and an institution and a department have been appropriately selected.
- (Append or Overwrite the Result Table) Users can designate whether the results of the next "Scout for Patients" action will append to the current result table, or overwrite it.
- (MRN Text Area) This is the text area where users can enter MRNs directly.
