Our Mission

Over the last decade, Siemens Healthineers developed CERA as a powerful toolbox consisting of building blocks for high performance 3D X-ray imaging across various imaging markets. The ability to combine knowledge from diverse application fields is keeping us in a unique position to generate and implement innovations that help you to augment your specific solutions.

Regular upgrades add exciting new features to CERA, which is designed to support your imaging needs with the following strategies in mind: Customization and Differentiation, Workflow Automation, Quality and Efficiency.

CERA functional scope

While 3D X-ray imaging applications are very specialized for their use case, they can be based on a set of common underlying technologies.

The functionality of CERA targets these common technologies by delivering algorithms and functions to be used in a variety of imaging markets. CERA thus offers the chance to leverage synergies between otherwise separated communities, applications, and markets.

    NDT Applications

    Typical applications in NDT comprise dimensional measurement or material testing during the manufacturing cycle of various products. 3D NDT X-ray imaging often has high demands on resolution and geometric precision and often involves very large amounts of data. CERA nicely supports those requirements.

    • Application-specific Trajectories
    • Phantom-based Alignment
    • Cone-beam Artifact Free Reconstruction
    • Field-of-view Enlargements
    • Beam Hardening Reduction
    • Scatter Reduction
    • Tera Voxel Renderer
    • Benchmarks

    Applications in Electronics

    Electronic testing typically deals with objects of anisotropic form factors, such as printed circuit boards, oftentimes with a specific interest in only certain regions distributed over that object. The small structures of interest demand high geometric magnifications during the scan.

    In addition, fast workflows are required in in-line applications. These requirements are often addressed with linear or circular tomosynthesis scans with a reduced number of projections. CERA's dedicated analytic and iterative algorithms provide high image quality in these scenarios. Geometric jitter caused by fast movement of manipulators and amplified by high geometric magnification is reduced by CERA's automatic jitter compensation. Visual assessment is enhanced with cutting-edge visualization techniques.

    • Jitter Compensation.
    • Iterative Reconstruction
    • Cinematic Rendering
    • Speed-up Methods

    Dental Imaging

    Digital volume tomography has become a standard application in dental imaging. Good algorithmic processing allows to create very compact and cost-efficient designs for highly specialized devices for imaging the human head. Typical challenges are detectors that do not cover the patient's entire head, limitations in the system mechanics, patient motion, and metallic dental fillings. This chapter presents the solutions CERA delivers for those challenges.

    • (Super) Short-scan Reconstruction
    • Half-beam Reconstruction
    • Noise reduction
    • Patient Motion Compensation
    • Metal Artifact Reduction

    How to use CERA

    CERA – Software for High-quality CT Imaging (9)

    From out-of-the-box to deep integration: customizable for any needs

    In order to be used, CERA requires a Windows 10 system with an Nvidia Graphics Adapter. To achieve high performance, an SSD is recommended for fast I/O. CPU performance, on the other hand, has no significant influence on CERA's processing speed. CERA can be accessed in a seamless range of depths of integration starting from a comfortable GUI up to an extremely fine-grained API integration. The chosen depth of integration can vary throughout the implementation, utilizing:

    • CERA XPlorer, an intuitive front-end application, offering an easy entry point and allowing fast prototyping.
    • Ready-to-use examples for most CERA features that come as pre-compiled programs and as C++ source code.
    • An easy-to-do high-level C-API integration, based on text-based configuration files that separate source code from feature and system configurations.
    • The low-level C-API allowing fine-grained control of all CERA features for a completely customizable workflow.

    CERA XPlorer

    The CERA XPlorer is an intuitive and efficient frontend to explore most CERA features. It can be used for rapid prototyping and also as an end-customer application. CERA XPlorer's functionality can be extended by executing customized command-line tools directly from its GUI. These can be the ready-to-use CERA examples or customer-created tools. This allows automatic, task-specific workflows to be created easily.
