feature_en: <p>The industrial X-ray CT device METROTOM 1500 from Carl Zeiss Industrielle Messtechnik GmbH allows for performing complex measurement tasks and nondestructive testing of metal and plastic parts. The high measuring volume and the powerful X-ray tube enable the measurement of larger parts up to around 0.5 m. As an advantage in comparison to tactile or optical measuring instruments, inner structures can be measured nondestructively. An unique feature is an implemented Hexapod robot which allows innovative measuring strategies.</p>

However, at the moment, detail sensitivity of iCT systems is evaluated by human operators, and therefore unreliable and expensive. There is a metrological need to develop traceable measurement and monitoring methods to assess detail sensitivity of iCT for the minimum detectable defect or flaw sizes without relying on human observers. This is an essential step to support the EU’s aims for the digital transformation in Europe and the United Nation’s sustainability goal for industry, innovation and infrastructure. However, new measurement methods, reference software, and standards need to be developed to fill this meteorological gap.</p><p> </p><p>The project aims to develop new test gauges that will help determine iCT detail sensitivity. Additionally, a new automated evaluation algorithm will be published that can determine the detail sensitivity of iCT data sets. Round Robin Tests will be conducted, and the results will be made available to relevant standard committees to demonstrate the accuracy of the developed measurement systems. The project will prepare a draft standard or EN ISO 15708-5 ‘Radiation methods for computed tomography — Performance Evaluation and Long-Term Stability’. Moreover, the project will publish free reference software with evaluation algorithms that comply with the standard draft, as well as a free data bank with standard reference images that can be used to validate software for conformity. Overall, these advancements will support Industry 4.0 in Europe and guarantee the competitiveness of modern iCT applications.</p>, , 2024-07-01, 2027-06-30, , 2027-06-30, Third Party Funds Group - Sub project, True>, <Project: Realistische Simulation realer Röntgencomputertomografie-Systeme mit basisqualifizierter Simulationssoftware - CTSimU2 (CTSimU2), CTSimU2, https://www.ctsimu.forschung.fau.de/, , Das Förderprojekt „Realistische Simulation realer Röntgencomputertomografie-Systeme mit basisqualifizierter Simulationssoftware - CTSimU2“ baut auf den Ergebnissen des Projektes CTSimU („Durchstrahlungssimulation für die Messunsicherheitsbestimmung beim Messen geometrischer Merkmale mittels Röntgen-Computertomographie“) auf. In diesem Projekt wurde eine objektive und standardisierte Bewertung von Simulationssoftwares zur Anwendung bei der Röntgen-CT für dimensionelle Messungen in Form eines (Basis-)Qualifizierungsframeworks erarbeitet. Dabei stand die ausreichende physikalische Korrektheit der Durchstrahlungssimulation im Vordergrund. Für die realitätsnahe Simulation einer CT-Anlage in einer Simulationssoftware (digitaler Zwilling) ist jedoch nicht nur die Korrektheit der Simulationssoftware selbst, sondern auch die Güte der Parametrisierung des realen CT-Systems in der Simulationssoftware entscheidend – dies stellt den Ausgangspunkt des 2. Projektes CTSimU2 dar. Die Parametrisierung eines CT-Systems in einer Simulationssoftware lässt sich in vier Schritte unterteilen: nach der Datenaufnahme am realen CT-System (Schritt 1) folgt die Auswertung der aufgenommenen Daten für die Generierung allgemeiner Parameterangaben (Schritt 2). Als letztes folgt die Übertragung der Parameter in die spezifischen Simulationssoftwares (Schritt 3) und die Validierung der resultierenden Simulationsparameter durch einen geeigneten Test (Schritt 4). Die Methodik der Datenaufnahme am CT und die Auswertung der Daten sollen in einem Werkzeugkasten allgemein beschrieben werden. Der dritte Schritt, die Übertragung der Parameter, ist softwarespezifisch und wird beispielhaft mit den vorhandenen Simulationssoftwares durchgeführt. Die Validierung der Parameter ist standardisierbar und soll durch einen zu entwickelnden Test geleistet werden, auf dessen Basis die ausreichend korrekte Simulation einer realen Anlage beurteilt werden kann. Endresultat des Projektes ist ein Richtlinienentwurf (z. B. für der Richtlinienreihe VDI/VDE 2630) zu diesem Test, der einen informativen Annex zum Stand der Technik bezüglich der Möglichkeiten zur Parameterbestimmung enthält. Mit einer Simulationssoftware, die die Basisqualifizierung aus CTSimU bestanden hat und einen Parameterdatensatz für ein reales CT-System enthält, der den Test aus CTSimU2 bestanden hat, sollten realistische Simulationen dieses CT-Systems möglich sein.

However, the digitization is also reaching its limits. Scanning robots cannot digitize documents whose condition due to natural ageing or external influences prohibit a conventional, optical based processing. Our own preliminary work has shown that the three imaging techniques X-ray Computed Tomography, Phase Contrast X-ray Computed Tomography and Terahertz Imaging are suitable for providing non-invasive insights into such documents, allow the acquisition of digital imaging information and are capable to re-enable an efficient automated process to digitalize cultural heritage documents.This research project is the first to develop a concrete digitization strategy or method for such documents. This structured evaluation will be based on a quality value that allows statements to be made about the expected result of digitization with one of the mentioned modalities for certain historical materials. From this, the most suitable imaging procedure can be determined. Based on these findings, a guideline for the digitization of fragile documents will be developed to predict the quality, feasibility and possible damage before a scan. In addition, algorithms will be developed that virtually process the generated data and make it readable for the human eye. Three concrete goals will be pursued to carry out the research project. By evaluating the modalities for selected historical materials, the most appropriate procedure for a specific document should then be identified. At the end of the project, a guide will be made available and the possibilities of each modality will be demonstrated by specifying material combinations and relevant parameters. It will be possible to test the variation of the recording parameters and to display exemplary results using the generated database. This also makes it possible to calculate a quality value. The basis for such a guide is the evaluation of the three modalities for relevant materials. For this purpose, realistic test specimen are produced. Both the scan quality and resolution as well as possible damage to the document must be considered. The guide will then be used to identify the most suitable procedure for a specific document. This statement is based on the mentioned quality value, which will also be used to predict the optimal digitization modality and the quality for an unknown document.The evaluation of several modalities as well as the development of algorithms are to be seen as central challenges of the research project. It will be possible to store endangered holdings in a digital format without destroying their structure through manual intervention. In the second funding phase, a multi-modal solution should be investigated in which disadvantages and limitations of individual modalities will be compensated by combining several modalities. <br />, , 2020-05-01, 2022-04-30, , 2022-04-30, Third party funded individual grant, True>, <Project: Advanced Computed Tomography for dimensional and surface measurements in industry (AdvanCT), AdvanCT, https://www.ptb.de/empir2018/advanct/home/, Advanced Computed Tomography for dimensional and surface measurements in industry, <p>Computed tomography (CT) is an aspiring contact-free measurement method which allows to determine the complete geometry of objects (inner and outer geometry including surface texture) typically not fully accessible to other measurement methods.</p> <p>To support dimensional metrology in future advanced manufacturing, the project will develop traceable CT measurement techniques for dimensions and surface texture. Open issues regarding traceability, measurement uncertainty, sufficient precision/accuracy, scanning time, multi-material, surface form and roughness, suitable reference standards, and simulation techniques will be clarified.</p> <p>Therefore the AdvanCT project will face the following objects:</p> <ol><li>To develop traceable and validated methods for absolute CT characterisation including the correction of geometry errors by 9 degrees of freedom (DoF).

However, to specify the measurement uncertainty for a certain measurand, twenty repeated measurements on a calibrated work piece have to be executed according to the state of the art (VDI/VDE 2630 Part 2.1). Since the measurement with real CT systems is time-consuming and cost-intensive, the numerical determination of the task-specific measurement uncertainty with simulation is currently researched. This method will be similar to the state of the art in tactile coordinate metrology (cf. VDI/VDE 2617 Part 7, GUM Supplement 1). Therefore, radiographic simulation softwares to simulate measurement tasks currently receive considerable attention. Simulations offer advantages through time-, cost- and resource-efficiency. However, the reliability of the different available simulation environments is currently not quantifiable. For end users to trust and apply the simulation systems, an evaluation of the simulation system’s accuracy is necessary. A standardized test procedure would also allow for a standard- respectively guideline-conformity in applications.</p> <p>Thus, the result of this project will be a draft for a new VDI/VDE standard VDI/VDE 2630 Part 2.2 “Restricted Qualification of Software for the Simulation of Geometrical Measurements using X-ray Computed Tomography”. On this basis, it will be possible to evaluate the suitability of a simulation environment for determining the task-specific measurement uncertainty. For this purpose, a test framework will be developed with which radiographic simulation software can be restrictedly qualified. A restricted qualification describes a qualification with regard to typical measurement scenarios that are perceived as relevant.</p> <p>Several steps are necessary to create the test framework. First, a requirements analysis defines the requirements for the used simulation software. These requirements are summarized in a specification. For the development of the test framework, it is necessary to convert the requirements of the specification into concrete test scenarios. For this purpose, reference geometries and reference data sets must be developed. Based on the simulation results for the various test scenarios, the corresponding simulation software can be evaluated. For this purpose, an evaluation matrix is developed. The final test framework will be validated by comparing real and simulated measurement data for positively evaluated simulation software based on the dimensional measurement results.</p> <p>In order to retain the normative character of this project, it will be ensured that this basic qualification with the test framework is also possible for other simulation software systems that are not represented in the project.</p> <p>This project is funded in the program <a>WIPANO</a><a>[RT1]</a> .

It enables the production, on demand, of customised implants which match the patient’s anatomy, with grafts that promote bone growth, as well as surgical guides that help the surgeons. The objective of this project is to provide a comprehensive basis to enable the safe use of medical AM products. Therefore, within this project off-the-shelf medical devices, patient specific guides and implants manufactured from patient image or numerical model will be qualified. This will guarantee their reliability to notified bodies and facilitate acceptance of AM in the medical sector.</p>, <p> The need for this project is justified by the fact that AM technology for medical applications has advanced at a much faster pace than regulations and quality controls. Patient specific implants (PSIs) and patient specific guides (PSGs) are to be used in highly critical applications governed by strict safety requirements from notified bodies and hence controlling the quality of the parts are of paramount importance. In order for the medical device industry to have confidence in the AM technology they need validated techniques to verify the finished parts and improve the process and reliability of the manufacturing chain.</p> <p> In order to validate these techniques, medical devices and standard objects, manufactured using different AM processes and materials, need to first be fabricated and characterised. Relevant aspects that have to be taken into account for these characterisations are the dimensions of external and internal geometry as well as internal defects, roughness and porosity, which will also influence the mechanical properties of the medical devices. Work is required to a) determine the precision limits of dimensional measurements and the relative sensitivity of industrial and medical XCT, and to b) qualify alternative, faster and cheaper nondestructive characterisation techniques, for routine control.</p> <p> The manufacturing process of patient specific medical devices with AM contains a number of steps, from the prior CT scan of the patient to the final manufacture and clinical use, each of which can introduce errors. The material used also has an influence on the parts as well on the category of processes used. Manufacturers need tools and protocols for the detection and quantification of defects so that the best material and manufacturing process can be reliably selected. It is therefore necessary to characterise the parts at various stages in the production and application process to quantify errors in the chain from medical imaging to clinical use.</p>, 2016-06-01, 2019-05-31, , 2019-05-31, Third Party Funds Group - Sub project, True>]>
