1. Product Introduction and Structure
A.1. Test Mold IntroductionThe test mold used in the imaging and photography modes consists of an attenuating body and a multifunctional test card (see Figure A.1), which can be used for tests such as dynamic range, spatial resolution, and low contrast resolution.
The attenuating body is a 25 mm thick aluminum plate with a purity of no less than 99.5%, placed as close as possible to the beam stop outlet.
Explanation:
1 – X-ray tube axis;
2 – Dynamic wedge;
3 – 16 low-contrast apertures, 4 mm in diameter and 2.5 mm deep (PAMM);
4 – kV inspection area;
5 – Central crosshair marker;
6 – 8 groups of objects with 10 mm diameter high contrast detail;
7 – Unstructured central area;
8 – Spatial resolution test chart;
9 – Numbers that the dynamic wedge can display on the image.
A.2. Module Composition
The multi-functional test card is composed of the following components, with a total thickness of 18.5 mm:
a) The base copper plate, with a thickness of 1.5 mm and a size of 300 mm × 300 mm. However, the thickness of the copper plate in the spatial resolution detection area is 1.1 mm.
b) The measurement copper step wedge for the dynamic range (see No. 2 in Figure A.1), with an outer diameter of 150 mm and an inner diameter of 110 mm. It consists of 17 steps, and the copper thickness of each step is specified in Table A.1. In the table, the copper thickness includes the thickness of the base copper plate (1.5 mm), and steps 1 to 8 are thinner than the base copper plate, while steps 10 to 17 are thicker than the base copper plate.
Key Features
All-in-One Calibration Design:
- Combines multiple test elements: circular hole array, linear resolution patterns, contrast sensitivity inserts, and geometric alignment markers.
- Covers spatial resolution, contrast detectability, dimensional accuracy, and system uniformity in one test card.
Precision Machined Structure:
- Rigid, flat panel design with high-precision embedded features (holes, line pairs, contrast inserts) manufactured to tight tolerances.
- Clearly marked structural components for easy identification of each test function during calibration.
Wide Application Compatibility:
- Suitable for routine quality control, equipment validation, and compliance testing of industrial X-ray scanners, security inspection systems, and digital radiography equipment.
- Eliminates the need for multiple separate phantoms, reducing calibration time and cost.
Durable & Reusable:
- Robust construction with a protective frame, ensuring long-term dimensional stability and repeatable test results even with frequent use.
Applications
- Industrial X-ray system multi-parameter calibration
- Spatial resolution and contrast sensitivity testing
- Defect detectability and dimensional accuracy verification
