Light produced by incident x-ray exposure on a flat panel image receptor plate (FPIR) is captured by which component?

The light produced by incident x-ray exposure on a flat panel image receptor plate (FPIR) is primarily captured by the thin film transistor (TFT) array. In a flat panel detector system, the TFT serves as a key component that converts the light generated from the scintillator into electrical signals. The TFT array consists of a matrix of transistors that collect these signals, enabling the conversion of the light into a digital image for processing by the computer.

The role of the TFT array is crucial because it allows for efficient readout of the image data without interruption, ensuring that the image can be processed quickly and with high fidelity. This processing capability is essential for producing clear and accurate images for diagnostic purposes.

While other components, like the scintillator, play a role in the initial conversion of x-rays to light, it is the TFT array that captures and processes that light, making it integral to the imaging workflow in flat panel radiography systems.
