18.7. Modules

In this section you can specify the settings for particular modules (Fig. 18.5).

To browse the detailed information about each module, select the module and click the Module info button. For some modules, special parameters are set. To do this, select the module from the Installed modules list and click the SETTINGS button.

18.7.1 Set Up Image Viewer Module

Select the Image Viewer module from the Installed modules and click the SETTINGS button. The Image viewer settings window contains five tabs with the following parameters:

1. General tab. The following parameters are set up:

   • default tool (the one that activates when opening an image). Options:

     • no tool;
     • Adjust W/L;
     • Ruler;
     • Angle;
     • ROI rectangle tool;
     • ROI ellipse tool;
     • ROI polygon tool;
     • Sync by point;

   • default mode. Options:

     • no mode selected;
     • DSA mode;
   • request for confirmation before deleting all annotations and measurements;
   • enable/disable the warnings of non-bilinear interpolation;
   • show TSE values in annotations;
   • enable/disable default synchronization of series image scrolling;
   • enable/disable slices scaling and position synchronization for various projections;
   • enable/disable display of the series list for the current study on the context menu. The function is enabled by default.

2. Image arrangement tab. The following parameters are set up:

   • the Confirm series closure on the arrangement changing option. Enabled by default. Enables or disables the series closure confirmation dialog when changing the arrangement if the selected template contains fewer viewing windows than the number of series open in the study. The option is exported to the file saving the current DICOM Viewer settings (see Section 18.9.1);

   • the Automatic series arrangement mode. Used by default. Series are arranged automatically, and the series window settings specified in the tab are applied to all newly created series windows. The following parameters are configured for automatic series arrangement:

     • Image arrangement — the number of columns and rows in which series images are arranged within a single series window. The default value is 1x1;
     • Image scrolling — the number of images scrolled at a time when multiple images are arranged in a series window. If One image at a time is selected, images are scrolled one at a time. If One screen at a time is selected, the number of images displayed in the series window is scrolled at a time. For example, with a 2x2 arrangement, four images are scrolled at a time. The default value is One screen at a time;
     • Sort by — the method for sorting series images. The available options are No sorting, Image number, and Image position and phase. The default value is Image position and phase.

   • the Custom series arrangement mode. Allows you to create your own series layout template. Selecting this mode displays the Automatic fill with series option and the series layout template configuration widget. The following parameters are configured for custom series arrangement:

     • the Automatic fill with series option. Disabled by default. Enables or disables automatic filling of custom template cells with series from the current study. The cell numbers in the template window determine the filling order;
     • the custom series layout template. The template is created by successively splitting cells into columns and rows and by merging previously split cells. By default, the template window displays a single cell numbered 1;
     • the settings of the selected template cell. The same series window parameters are configured for the cell as for automatic arrangement: image arrangement, scrolling method, and series image sorting. If multiple cells are selected, the settings area displays the values of the first selected cell;
     • splitting a cell. To split a cell, select it, enter the required numbers of columns and rows in the Columns and Rows numeric fields, and click the SPLIT button. If multiple cells are selected, the SPLIT button is disabled. When a cell is split, its settings are applied to all child cells;
     • Primary splitter. This parameter determines the order in which a cell is split when it is divided into multiple columns and rows at the same time, and affects cell resizing in the corresponding template subtable. With Horizontal, the cell is first split into columns, and then each column is split into rows. With Vertical, the cell is first split into rows, and then each row is split into columns. The default value is Horizontal;
     • merging cells. To merge cells, select multiple cells and click the MERGE button. You can merge adjacent cells within the same subtable or adjacent subtables if all their child cells are selected. If only one cell is selected or the selected cells cannot be merged, the MERGE button is disabled. When cells are merged, the new cell uses the settings of the cell with the lowest sequence number.

   These parameters can be set for a specific modality. To add a modality, click the ADD button and enter the name of the modality in the dialog that appears. To change the settings for a previously added modality, select it in the Settings for modality drop-down list. To delete the selected modality click the REMOVE button.
