The Positioning Cursor Error Phantom is a precision calibration tool designed for industrial X-ray CT systems, fully compliant with the Chinese national calibration specification JJF 2043-2023. It is used to verify the accuracy of cursor positioning and geometric alignment in computed tomography (CT) equipment, ensuring reliable dimensional measurement and inspection results.

Standard-Compliant Design: Manufactured in accordance with JJF 2043-2023 requirements for industrial X-ray CT device calibration, ensuring test validity and regulatory compliance. High-Precision PMMA Construction: Made from homogeneous, high-transparency PMMA (acrylic) material, with a cylindrical structure (35mm diameter, 20mm height) and clear cross-shaped positioning marks. Embedded Reference Objects: Contains internal high-contrast reference elements with strict spatial geometric relationships to surface markers, enabling accurate cursor error detection. Low Insertion Error: Internal component positioning error ≤ 0.5 mm, providing stable and repeatable calibration results for long-term use. Easy to Use: Compact, self-contained design with visible alignment features, suitable for routine calibration and performance verification in industrial CT labs.
