Question

The film transistors (TFT) are found in which type of digital system?

a. CR (Computed Radiography)
b. DR (Digital Radiography)
c. PACS (Picture Archiving and Communication System)
d. MRI (Magnetic Resonance Imaging)

Answer 1

TFTs are used in Digital Radiography systems, where they help convert x-rays into electrical signals to capture digital images.

Step-by-step explanation:

The correct answer to the question of where Thin Film Transistors (TFT) are found is b. DR (Digital Radiography). TFTs are used in the flat-panel detectors of digital radiography systems. In contrast to traditional film-based radiography, digital radiography captures images using a flat-panel detector that converts x-rays into electrical signals. These signals are then read out by the TFT array, allowing for the digital image to be viewed and manipulated on a computer. This contrasts with Computed Radiography (CR), which uses photostimulable phosphor plates to capture image data, and Magnetic Resonance Imaging (MRI), which is based on nuclear magnetic resonance and does not use TFTs.
