Computed Tomography An Overview: Overview

Computed tomography has advanced rapidly through innovations that improve image quality while reducing radiation dose. AI-enhanced reconstruction yields sharper, cleaner images, whereas photon-counting detectors enhance tissue characterization and diagnostic accuracy. Ultra-low-dose protocols, spectral imaging, and faster scanning techniques are expanding clinical use and improving efficiency, particularly in emergency care. These developments strengthen CT's role as a safer, more precise, and more effective tool in modern medical practice.
