Chest photofluorography, or abreugraphy (better known as mass miniature radiography in the UK and miniature chest radiograph in the US), is a photofluorography technique for mass screening for tuberculosis using a miniature (50 to 100 mm) photograph of the screen of an X-ray fluoroscopy of the thorax, first developed in 1936.
From the early days of radiation therapy, X-rays or gamma rays were used to develop large format radiographic films for inspection. With the introduction of cobalt-60 machines in the 1950s, radiation went deeper inside the body, but with lower contrast and poor subjective visibility.
Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices.
Spectral imaging is an umbrella term for energy-resolved X-ray imaging in medicine. [1] The technique makes use of the energy dependence of X-ray attenuation to either increase the contrast-to-noise ratio, or to provide quantitative image data and reduce image artefacts by so-called material decomposition.
EOS is a medical imaging system designed to provide frontal and lateral radiography images, while limiting the X-ray dose absorbed by the patient in a sitting or standing position. The system relies on the high sensitivity of a detector ( multi-wire chamber ) invented by Georges Charpak , which earned him the 1992 Nobel prize .
Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.

This process is unlike a diagnostic X-ray, where external radiation is passed through the body to form an image. [citation needed] There are several techniques of diagnostic nuclear medicine. 2D: Scintigraphy ("scint") is the use of internal radionuclides to create two-dimensional images. [4]
