What does the acronym "TFT" stand for in digital radiography?

The acronym "TFT" in digital radiography stands for "Thin Film Transistor." This technology is pivotal in the construction of flat-panel detectors used in digital imaging systems. TFTs serve as the building blocks for electronic components in these detectors, allowing for the effective conversion of x-ray signals into digital images.

In a digital radiography system, the TFT gets integrated into the pixel structure of the detector, enabling the collection and transfer of electrical signals generated by the x-ray exposure. The use of TFT technology is crucial because it improves image quality and enhances the speed of image acquisition, which is essential in clinical settings. The robustness and efficiency of TFTs make them ideal for managing the large volume of data generated in medical imaging.

Understanding the role of TFTs helps in comprehending how digital radiography systems function and the advancements they represent in medical imaging technology.
