Radiografisk

Radiografisk is an adjective used principally in Scandinavian languages to describe radiographic imaging and techniques that use ionizing X-ray radiation to visualize the internal structure of the human body or other objects. In medicine, radiography encompasses projection radiography, fluoroscopy, and newer digital methods such as digital radiography and computed radiography, which differ in how the image is captured and displayed. The basic principle is the differential absorption of X-rays by tissues of varying density, which creates contrast on an image.

Plain radiography produces two-dimensional pictures from a single projection. Fluoroscopy provides real-time imaging and is often used to guide procedures or study motion. Digital radiography uses solid-state detectors or computed radiography plates to convert X-ray photons into electrical signals, enabling rapid image generation and post-processing.

Applications are broad: skeletal radiography for fracture evaluation, thoracic radiography for lung and heart conditions, abdominal imaging, and specialized examinations such as mammography and dental radiography. In industry, radiography is used for non-destructive testing of materials and welds.

Safety is a central concern. Radiation exposure is minimized through principles of ALARA (as low as reasonably achievable), shielding, optimized exposure settings, proper positioning, and the use of protective equipment. Training and licensing for radiographers or radiologic technologists ensure standardized image quality and patient safety.

The discovery of X-rays by Wilhelm Conrad Röntgen in 1895 marked the beginning of radiography, followed by rapid advances in image quality, digital detectors, and safety practices that shaped modern radiographic practice.
