Computed Radiography: Digital Imaging Advancements in Diagnostic Medicine
Computed radiography (CR) is a digital imaging technology that replaces conventional X-ray film with phosphor imaging plates, enabling rapid, high-resolution image acquisition and processing. After exposure, the imaging plate is scanned by a laser, producing a digital image that can be enhanced, stored, and transmitted electronically.
CR offers several advantages over traditional radiography: lower radiation doses, faster image acquisition, enhanced contrast resolution, and immediate image review. Integration with PACS and hospital information systems facilitates efficient storage, retrieval, and sharing of patient images, supporting telemedicine and remote consultations.
Applications of CR include orthopedic imaging, chest radiography, dental imaging, mammography, and emergency diagnostics. Advanced features such as image enhancement, edge detection, and automated measurements improve diagnostic accuracy. Computed radiography has played a pivotal role in the transition from film-based to fully digital radiology, enhancing workflow, reducing processing time, and improving patient care efficiency.
