Getting Started

To quickly get started with the application, simply download this zip file, which contains the current stable release version. Extract the folder to your file system and run the CHOP-fMRU_Assistant application.

Configuration

The program maintains a directory containing the various studies that are imported. Create a directory in your file system that will be dedicated to this purpose and change this setting by choosing Settings from the menu. Select Change Directory. Select the directory that will contain the database and click OK. Save the change.

Importing a Study

To import a study into the database, open the Study menu item and select Import Study. Navigate to the directory containing the DICOM files and click OK. The import process can be time consuming, as all DICOM headers are fixed when imported. Beware that the program will recursively add any DICOM found in this directory. This means that if multiple studies are contained in one directory, even if they are contained in subdirectories, these will be imported into the database. Once finished, the last imported study will be selected.

##Changing to a Different Study To change to a different study within the database, open the Study menu item and select Change Study. The studies are presented as a tree, with patient names as the roots and accession numbers as nodes. Highlight the accession number of the desired study and click OK.

##Deleting a Study Simply change to the study of interest using the Change Study dialog as above. Once the study that you wish to remove is listed in the status bar at the bottom of the main form, open the Study menu item and select Delete Study. This will permanently delete the selected study from

##Editing the Study The study can be edited to make importing into CHOP-fMRU feasible. Change to the study of interest using the Change Study dialog as above. Then, click the Study Editor button. The Study Editor form will appear.

Different series in the study can be selected with the ComboBox in the top left. The series are listed based on their Series UIDs, which are normally hidden in a PACS environment. Selecting a series will show the series description underneath the ComboBox. The images for the study will be sorted by time and position and represented as a grid in the panel on the left. The selected image will be displayed on the right. The grid on the left can be navigated by clicking and using the arrow keys.

CHOP-fMRU requires that only dynamic images be imported. Other series can be excluded by clicking the Exclude series button. These are moved to the exclude directory within the input_files directory of the CHOP-fMRU_Assistant database.

CHOP-fMRU also requires that the dynamic series be complete. That is, every slice position and every time within the square grid has an associated image. If there are missing images, the import will fail. This can be addressed by excluding any slice positions or times from the study that do not contain enough members. Select the desired image and click Exclude this time or Exclude this position, as desired.
