Watson-Odelca x-ray set for mass miniature radiography, Europe, 1960-1961

Watson-Odelca photo-fluorographic x-ray set for mass miniature radiography (100mm images), by Watson and Sons (Electro-Medical), London, England, and N.V. Optische Industrie (De Oude Delft), specialist makers of X-ray equipment and optical technology, Delft, South Holland, Netherlands, used at Ilford Chest Clinic, London, England, where patients diagnosed with tuberculosis could be treated, 1960-1961

Mass miniature radiography was used to diagnose tuberculosis in Britain from 1936 onwards – in an attempt to control the disease by catching those affected as early as possible. People who appeared outwardly healthy might still show signs of tuberculosis, such as lesions in the chest, and so could spread the disease. This cream coloured machine produced X-ray images that were just 100 mm high. If physicians were unsure about a miniature X-ray when viewed on a projector, the patient was sent to hospital for a full chest X-ray.
