What is the function of detectors in CT tomography?

Detectors in CT tomography function to capture the X-ray photons that pass through the body after being attenuated by different tissues. They convert these photons into electrical signals, which are then processed to reconstruct detailed cross-sectional images of the internal structures. This enables visualization of various anatomical features and helps in diagnosing medical conditions. The accuracy and sensitivity of the detectors significantly impact the quality and resolution of the resulting images.
