How is image data acquired after the x-ray photons pass through the patient?

After X-ray photons pass through the patient, they strike a detector, which can be either a film or a digital sensor. In digital systems, the detector converts the X-ray photons into electrical signals, which are then processed to create a digital image. The varying degrees of X-ray absorption by different tissues result in contrast in the final image, allowing for visualization of anatomical structures. This image can then be viewed, analyzed, and stored for diagnostic purposes.
