ZEN core 3.11

Base Software

• The position of the scale bar inserted into images is now configurable. The initial position can be set in absolute or relative coordinates.
• The Tool set functionality, design and creation workflow has been improved. It is now also possible to add a description for each tool set.
• The Export has been moved from the Free Mode Exit dialog and is now available in the general Free Mode application bar.
• We reworked the Download window in the AI Template manager for instance segmentation models. This allows now filtering and sorting of instance segmentation models available on arivis Cloud. The Download window now also gives more details on the selected models such as supported pixel types or number of channels the model was trained on.

Motorized Acquisition Toolkit

Additional options have been added to the Tiles Acquisition workbenches. It is now possible to switch between the acquisition modes (Meander, Comb, Spiral) and the acquisition order for multiple tile regions can be set.

3D Toolkit

The 3D viewer also shows orthogonal 2D projections in XZ, ZY and XY. In order to deeply investigate a 3D volume visually, the user can work with slices and now also set the thickness of these slices in the 3D viewer. By using maximum, minimum or average intensity projection, fine regions of interest can be visually identified.

2D Toolkit

In the Frames step of the Image Analysis Wizard it is now possible to directly see the size of the defined frame in scaled units. If it is necessary that a frame of a certain size is created, this is now easily possible in the Image Analysis Wizard.

Additional measurement features were introduced to allow calculating the area covered by detected objects in a frame with respect to the whole image:

• Image Plane Area Percentage: The percentage of area of the regions in relation to the area of the whole image including areas without pixel values.
• Image Plane Data Area Percentage: The percentage of the area of the regions in relation to the area of the whole image, only for areas which contain pixel values.

In order to have a more consistent naming with the newly introduced features, the existing features were renamed:

• Frame Area Percentage (old name: Area Percentage)
• Frame Data Area Percentage (old name: Image Area Percentage)
• Frame Area Percentage Cut (old name: Area Percentage Cut)

These features calculate the area of the detected objects with respect to the defined measurement frame.

Existing image analysis settings created with older ZEN core versions will still work without adaptions.

GxP Toolkit

• The logging functionality in GxP mode has been improved and additional details have been added to several logging parameters.
• It is now possible to reject results in GxP mode when countersigning them. These are marked with the reason for rejection in Browse Results.
• The exported Audit Trail PDF is now secured and cannot be easily edited anymore.

Technical Cleanliness Analysis (TCA)

Note: In April 2023, the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) awarded ZEISS with its machine learning based object classification in TCA first place in the REINER! Fraunhofer Technology Award. ZEISS One Scan Technology for TCA and particle analysis has been granted a US patent (US 11,692,928 B2) in July 2023.

General improvements

• The reporting in TCA was extended and offers new the adjustable selection of the number of largest particles per type.
• The width size classification in the TCA standard template was extended by a new parameter: max. inscribed circle.
• Performance optimization was achieved for the Size Distribution View (filter options for the particle gallery) and the TCA report generation is now faster by a factor up to 10 times depending on the workstation and job configuration.
• Dual camera: the particle shift correction persists after closing the job template.

Approval rating and display of approval results

• The approval rating for particle counts in class all is now based on a direct actual-target comparison. Both options for the definition of allowed particle counts per size class support this mode.
• The Size Distribution View displays for the size classification table in addition the allowed number of particles per type and size class. This enables a direct comparison of measured particle counts with defined limit values from the acceptance criterion and is also displayed in the archived size classification tables and the archived result viewer (=ParticleDocument).

Particle type differentiation

• For particle type classification the Optimized Mode was introduced. The Optimized Mode provides a significantly improved automated classification of darker metallic particles. The new mode increases the productivity by time saving during particle inspection and revision.

Non-Metallic Inclusion Analysis (NMI)

• The NMI standard template offers new the option to select individual inclusion width parameter for type A, C and D. The functionality is available for ASTM E45, ISO 4967, JIS G0555 and GB/T 10561. The new mode allows enhanced comparability between ASTM E45 and ISO 4967 (and related standards).
• The standard specific inclusion table was significantly extended and contains now information on the applied classification width parameter for type A, C and D and results for additional inclusion width parameter including the new parameter area/length. The table provides deep insights and a transparent overview of the results of the classification by inclusion size and type.

ZEISS Zaphire Connector

The Zaphire Connector has been discontinued with ZEN core 3.8 due to technical incompatibilities. Any customers wanting to directly transfer images from ZEN core to Zaphire have to use ZEN core 3.6 or earlier.

Smartproof 5 and Visioner 1

• ZEN core 3.11 is not compatible with the Smartproof 5. The ZEN core version for Smartproof 5 has been discontinued and the last compatible version is ZEN core 3.8.
• ZEN core 3.11 version must be ordered also for Visioner 1. The previously existing special configurations are not available anymore.
• For upgrades to ZEN core 3.11 the general ZEN core 3.11 upgrade numbers do apply also for Visioner 1.

ZEN core starter

• For ZEN core starter 3.11 only a limited number of options are available. Do not upgrade a ZEN core starter version 3.4 or earlier and licensed modules as this might result in a loss of functionality.
• In general, the included functionality for ZEN core starter has increased reducing the need for some of the previously needed modules.
