X-ray Markers, also known as: anatomical side markers, [1] Pb markers, lead markers, x-ray lead markers, or radiographic film identification markers, are used to mark x-ray films, both in hospitals and in industrial workplaces (such as on aeroplane parts and motors). They are used on radiographic images to determine anatomical side of body ...
A feature of a radiograph that represent some kind of pathology was first coined "Roentgen signs" after Wilhelm Röntgen, the discoverer of the X-ray. [2] As the field of medical imaging developed and expanded to include numerous imaging modalities, imaging biomarkers have grown as well, in both quantity and complexity as finally in chemical ...
Radiochromic film is a type of self-developing film typically used in the testing and characterisation of radiographic equipment such as CT scanners and radiotherapy linacs. The film contains a dye which changes colour when exposed to ionising radiation, allowing the level of exposure and beam profile to be characterised. [1]

X-ray: uses X-rays to produce images of structures within the body; video link: Contrast media for X-rays: to provide a high contrast image of the details of the viscera under study; e.g. salts of heavy metals, gas like air, radio-opaque dyes, organic iodides, etc. Echocardiography machine: sonography of the heart is done here to know its ...
Taking an X-ray image with early Crookes tube apparatus, late 1800s. Radiography's origins and fluoroscopy's origins can both be traced to 8 November 1895, when German physics professor Wilhelm Conrad Röntgen discovered the X-ray and noted that, while it could pass through human tissue, it could not pass through bone or metal. [1]
Autoradiography of a coronal brain slice, taken from an embryonal rat. GAD67-binding marker is highly expressed in the subventricular zone.. An autoradiograph is an image on an X-ray film or nuclear emulsion produced by the pattern of decay emissions (e.g., beta particles or gamma rays) from a distribution of a radioactive substance.
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.
