Digital Radiography (DR) is a new X-ray imaging technology developed in the 1990s. With significant advantages such as faster imaging speed, more convenient operation, and higher image resolution, it has become the leading direction in digital X-ray photography. The core technology of DR is precisely the flat panel detector. Understanding the performance indicators of detectors helps improve image quality and reduce X-ray radiation dose.
In conventional X-ray examinations, flat panel detectors enable DR equipment to quickly acquire high-quality human body images. Compared to traditional film imaging, imaging speed is significantly increased, image resolution is higher, and even subtle lesions are easily detected.
Specifically used for early breast cancer screening. The high spatial resolution of flat panel detectors allows doctors to clearly observe details such as microcalcifications and tumor edges within breast tissue. Amorphous selenium direct conversion detectors have a spatial resolution of pixel size ≤85μm and a peak quantum detection efficiency of 80%, making them particularly suitable for high-precision imaging applications like the breast.
During interventional procedures, flat panel detectors provide clear real-time images of blood vessels, tissues, etc., helping doctors accurately guide the operation of surgical instruments. Dynamic flat panel detectors can image under pulsed or continuous X-ray exposure, focusing on acquisition speed and sensitivity efficiency, emphasizing high-throughput, low-latency real-time image processing.
