TZ1001 high-energy X-ray industrial DR/CT rapid inspection system

System Overview:
        The TZ1001 high-energy X-ray industrial DR/CT rapid detection system uses 9MeV high-energy electron linear accelerator as the radiation source, and the high-precision CT scanning mechanical system completes the scanning movement. The data is completed by the CdWO4 crystal line array detector and the wide dynamic range low-noise electronics system After collecting, data conversion and processing, the DR image and tomographic image of the detected workpiece are reconstructed.

System principle:
        The ray source generates fan-shaped high-energy X-rays in a controlled state; the X-rays are attenuated after penetrating the workpiece to be inspected, and the different attenuation levels reflect the internal information of the workpiece; the detector and subsequent systems accept X-rays and convert them into digital signals; In the DR scanning process, the overall projection data is obtained through the translation of the workpiece. In the CT scanning process, the projection data is obtained from multiple angles through the rotation of the workpiece; the acquired projection data is processed and reconstructed to obtain the DR/CT digital image .
