How to choose a digital imaging system flat panel detector?

With the widespread application of digital imaging technology in medical diagnosis, industrial non-destructive testing (NDT), and security inspection, flat panel detectors (FPD) have become one of the core equipment for global procurement. However, in the face of complex technical parameters and brand competition, how to make the right choice for purchasing a suitable flat panel detector?

Firstly, for the selection of flat panel detectors based on technical parameters: matching the core indicators of the application scenario
1. Sensor type and performance
-Amorphous silicon (a-Si): High cost-effectiveness, strong stability, suitable for conventional industrial testing and basic medical equipment.
-CMOS/IGZO: High resolution (such as 3072 × 3072 pixels), low noise, suitable for dynamic imaging and interventional medical scenes (such as angiography).
-Dynamic range (≥ 16 bits): Ensure rich imaging layers and avoid image distortion at low doses.
2. Size and dose optimization
-Standard size (17 x 17 inches): Covering over 90% of human detection needs, avoiding the risk of multiple exposures and dose overlap caused by small sizes (such as 14 x 17 inches).
-Low radiation technology: For example, BOE’s 4343W backplate provided to Varex can reduce X-ray dose by 80%, which meets European and American medical safety standards.
3. Software system and compatibility
-50% of the imaging quality depends on software algorithms, and it is necessary to verify whether the workstation supports AI assisted diagnosis, multilingual interface, and open API interface.
This is the main direction when choosing a flat panel detector.
Then it comes to brand selection and certification
Medical field: FDA/CE certification is required; Choose those with outstanding cost-effectiveness.
In the industrial field, priority should be given to high temperature resistance (-20 ℃~60 ℃) and anti vibration design, such as Vieworks’ IP54 protective model.
The above are some suggestions for choosing a flat panel detector, but you also need to consider your budget and actual usage situation.
