The image analysis is automatic and the only action requested to the user is the selection of the phantom type.
In order to start the the analysis it is possible to use the menu Actions | Analyse or click on the analyse button on the toolbar. If it is possible to select among different phantoms, the following dialog appears.
This allows the user to select which is the phantom that generates the image. If the license allows only one phantom, this window will not appear and AutoPIA will assume that the image has been generated with the phantom.
Select the right phantom and click on Ok. AutoPIA will start the image analysis while showing a progress bar. Just under the progress bar there is a Cancel button that can be used to interrupt the analysis. The analysis lasts for a while depending on the image features. Normally it never lasts more than 1 minute, but in certain circumstances it could last something more (seldom it reaches two minutes).
When the analysis is completed, the results are presented.
The result of the analysis contains lot of information, especially for phantoms containing lot of details. In order to allow an easy and efficient navigation through results, they are structured in hierarchical fashion, which is represented on the left, inside the view called navigation. Every node of the tree corresponds to a detail (or collection of details) and when selected, its features are shown in the other views of the working area:
- the region of the image containing the detail is shown in the Close-up view
- the detail image quality indices are listed inside the Measures view: the first table contains the IQIs of the detail, while the second table lists the IQIs of the sub-details (if any) CyberQual AutoPIA AutoPIA – User Manual Version 11/2014
