#x-ray imaging
- Actinography — A historical medical and scientific term used in the past as a synonym for radiography or the technique of obtaining internal structural images of solid bodies using X-rays or other active radiant beams. In old applied physics, it also defined the general method of printing or recording onto a photosensitive film the chemical effects directly caused by exposure to an electromagnetic wave flux within the ultraviolet spectrum.
- Actinoscopy — A historical medical term used in the past to designate fluoroscopy or radioscopy; a method of direct, real-time visual examination of the internal structures of the human body by projecting radiological shadows onto a fluorescent screen under the action of X-rays. This early structural technique allowed physicians in the last century to observe organ movements (such as heart pulsations or lung respiration) without developing a photographic plate.
- Amidotrizoate — An iodinated organic compound with an aromatic structure, clinically used as a water-soluble, high-osmolality radiological contrast agent, also known as diatrizoate. Due to the high number of iodine atoms in its molecule, it strongly absorbs X-rays, facilitating clear structural visualization of blood vessels, the urinary tract (urography), and the gastrointestinal system during diagnostic imaging investigations.
