User Interface

Starting the PCARDP Tool

The PCARDP tool is started with the Cardiac PET button from the PMOD ToolBox

PCARD Start Button

or by directly dragging image files onto the above button.

Organization of the PCARDP User Interface

The user interface of PCARDP consists of four pages which can be selected by tabs. The color layout and pages name change based on the analysis scenario.

Particularly we have a common interface for the dynamic and static PET analysis as illustrated below:

DynamicStaticInterfacePages

  1. DB Load page: This page is only available when using PMOD databases.
  2. Reorientation page: This page serves for the spatial reorientation of the data to the standard short axis orientation and the definition of the myocardialsegments.
  3. Kinetic Modeling page: This page deals with the kinetic modeling of the segmental TACs, the parametric mapping and the exploration of the results.
  4. Compare page: This page allows comparing the stress and rest outcome as well as the comparison with a normal database, if one is available.

The interface slightly changes for the gated analysis:

  3. GATED Analysis: This page allows exploration of the results and deals with the gated analysis.
  4. Compare page: This page allows comparing various stress and rest gated analysis outcome.

Step-Wise Processing

Data processing is organized by a stepwise progression from one page to the next towards the end result. On each processing stage the user has to take some action such as data loading, alignment inspection or parameter configuration, and then start the next processing step with the action button located in the lower right. As soon as the result is calculated, it will be shown on a new page representing the new processing stage. To repeat a calculation with modified parameters, the action button in the lower right has to be activated again.

Convenience Buttons

In some places a button the following buttons appear:

Hide some of the user interface elements to free some space. With the panel hidden, the icon changes to . When this button is activated, the panel is shown again. This functionality may be helpful with small computer displays.

Reset the parameters to their default values.

Clearing Studies

When new data is loaded, the previous data and results are cleared. However, it is also possible to explicitly reset the tool closing all image series in the PCARDP tool with Close all studies button available on the lateral taskbar. Alternatively, this can be done selectively for STRESS and REST series by selecting the X button to the right of the image.
