X-ray flat panel detectors are widely used in security, industrial and medical fields. In the medical field, it includes all X-ray equipment except CT, including DR, DRF (dynamic DR), DM (breast), CBCT (dental CT), DSA (interventional, vascular), C-arm (surgery) and many more.
From the end of the 20th century to the present, many well-known domestic and foreign manufacturers have developed their own flat panel detectors. Amorphous silicon has become the most mainstream flat panel detector due to its mature technology, good adaptability and low cost. However, amorphous silicon flat plates are not the best choice for dynamic imaging applications such as breast, dentistry, and surgery. Therefore, in the field of breast, Hologic invented the amorphous selenium flat panel detector; in the fields of dentistry (CBCT), surgery (C-arm) and other fields, Dalsa first developed a CMOS flat panel detector. It has also successfully developed and mass-produced small and medium-sized CMOS detectors.
The digital ray detection technology with CMOS detector as the recording medium has high detection accuracy, good temperature adaptability and strong structural adaptability. The detection units of the CMOS ray scanning detector are arranged in a line array, which needs to perform relative scanning motion during detection, and collect and assemble a complete transillumination projection image line by line. The design of the inspection tooling is introduced, and the fixation and position adjustment of the detector and the relative movement with the inspection workpiece are completed. The detector configuration and calibration, transillumination method selection, motion speed control, inspection parameter optimization, defect quantitative analysis and image archive management in inspection applications are introduced. The application results show that after process optimization, CMOS detectors can realize the ray inspection of most product parts. As a new technology, CMOS has a very broad development prospect and strong vitality, and may become the future development direction of this industry.
