What is the primary purpose of a thin film transistor in a fluoroscopy imaging system?

The primary purpose of a thin film transistor (TFT) in a fluoroscopy imaging system is to convert X-rays into digital signals. In fluoroscopy systems, TFTs play a crucial role in the process of image acquisition and display. When X-rays pass through a patient and interact with the image receptor, the TFT helps in detecting these X-rays effectively and converting the resulting electrical signals into digital data. This digital data can then be processed and displayed as images, allowing for real-time visualization of the interior of the body.

TFT technology enhances the efficiency of image collection, as it allows for faster readout times and improved image quality. This is particularly important in fluoroscopy, where quick succession of images is often necessary for monitoring dynamic functions within the body. The ability of the TFT to facilitate the rapid conversion of X-rays into digital signals is what makes it an essential component in modern fluoroscopy equipment.
