   • Customize the cache memory limits for the selected imaging device.

   By default, the imaging device is selected by the program automatically and is shown on the drop-down list as the Auto option. The cache memory limits that can be changed are displayed for this device. For each device on the drop-down list, the amount of memory available for caching is displayed.

   The fields for setting cache memory limits are provided with a restore recommended value button . The restore recommended value button is displayed when the limit value provided is different from the recommended value. To restore the recommended value of a cache memory limit, click the button in the respective field.

   You cannot customize the cache memory limits for the CPU (software). The cache memory limits for this device are calculated on the basis of the values provided in the General tab (see Section 16.1).

2. Segmentation tab. The following parameters are set up:

   • sets the default structure opacity;

   • option Invert edit mask on MPR can be checked/unchecked;

   • option Confirm on the structure removing activates the confirmation dialog box when deleting a structure. The option is enabled by default;

   • option Collapse new structure on creation determines whether the newly added structure element on the segmentation panel list shall be collapsed or not. If the option is enabled, the added structure is collapsed, if the option is disabled, it is not. The function is enabled by default.

     A new structure element is added to the list on the segmentation panel when the following actions are performed:

     • a new structure is created;

     • an existing structure or structure mask is copied;

     • a surface is exported to a new structure;

     • a series containing segmented structures or 3D models is opened;
