工業X光電腦斷層掃描之驗證與量測技術

計量與檢測技術在工業製造中至關重要，它們能夠實現精確的品質控制、流程優化、支援產品設計和開發、確保查證和標準、實現故障分析和可追溯性。從而製造出高品質的產品，創建更有效率的生產流程。傳統尺寸計量與檢測技術皆以外觀形貌分析為主，針對內部結構XCT (X-ray Computed Tomography，X光電腦斷層掃描)技術因具有非破壞性與高解析度等特性，工業上已導入XCT進行工件內部結構計量與檢測，由於XCT量測方法與傳統影像技術不同且影響因子相當多，為確保XCT量測的準確性能夠對複雜的三維結構和內部特徵進行非破壞性且高精度的測量，XCT系統驗證是相當關鍵的部分，本文將說明XCT關鍵性能參數及影響性能因子與國際驗證技術的標準與指南，期望有利於讀者了解工業電腦斷層掃描系統之驗證與計量與檢測技術。

Metrology and inspection technologies are crucial in industrial manufacturing, enabling precise quality control, process optimization, supporting product design and development, ensuring certifications and standards, and enabling failure analysis and traceability. This results in high-quality products and a more efficient production process. Traditional dimensional measurement and inspection technologies are mainly based on appearance morphology analysis. For internal structures, XCT (X-ray Computed Tomography, X-ray computed tomography) technology has been introduced in industry for measuring and inspection the internal structure of workpieces due to its non-destructive and high-resolution characteristics. Since the XCT measurement method is different from traditional imaging technology and has many influencing factors, in order to ensure the accuracy of XCT measurement, complex three-dimensional structures and internal features can be measured non-destructively and with high precision. XCT system verification is a very critical part. This article will explain the key performance parameters of XCT, the influencing factors of performance, and the standards and guidelines of international verification technology. It is hoped that it will help readers understand the verification, measurement and detection technology of industrial computed tomography systems.
