Room dedicated to Prof Mrs Röntgen
Professor Röntgen discovered the existence of X-rays on November 8 , 1895 through experiments in his laboratory in Würzburg. After 6 weeks of further experiments he invited his wife to his laboratory on the evening of December 22nd and demonstrated to her how a photo of her left hand looked like after radiation. The invention and properties of x-rays were carefully described and officially published on December 28,1895 In the "WÜRZBURG ROOM" we reconstruct the evening of December 22nd and show the equipment used for the "radiography" of Mrs Röntgen's left hand.
1 * a vacuum pump with a mercury pressure indicator connected to
2 * the X-ray generating device , itself connected to
3 * electrical power bobbin
4 * Mrs Röntgen's hand
5 * the fluorescent screen
6 * the picture of the hand on a photographic plate
Also shown is the first page of Röntgen's report of his experiments and a camera used to make pictures and provide evidence of the X-ray device he had invented.
Room dedicated to Prof J. Cornelis.(Neuro-radiologist UCL/KUL)
Professor Cornelis headed the neuro-radiology department in the academic hospital of the university of Louvain in the nineteen sixties. In addition to images of the skull taken from different angles, a large number of tomographs were produced with the "Polytome", an instrument developed by Philips. With the injection of contrasting agents such as "Lipidiol ®" images could be produced of the spinal marrow (myelographs), the brain( encephalographs) and arteries(arteriographs). A built in cassette device developed by the firm De Man allowed an easy switch of the radiographic parameters to optimise the imaging of different tissu

This widely-distributed "Art-Nouveau" model, elaborated by A-J. D'Arsonval, (France, 1851-1940) and manufactured by G. Gaiffe (France 1857-1943) enjoyed an excellent reputation and over the years underwent a number of improvements. Here, it's shown with the famous Rochefort high voltage coil at the top of the device supplied by alternating current through a mercury and gas atmosphere turbine at the bottom. At the top, 2 Villard gas valve tubes (rectifier) were placed; later replaced by the hot cathode valve tube or Kenotron developed in 1914 by S. Dushman (USA, 1883-1954) of GE's researched laboratory. After 1915, the addition of a filament transformer enabled the case of the new powerful vacuum W. Coolidges tubes(USA, 1873 -1975). d'Arsonval apparatus with Oudin's resonator : High frequency instruments are constructed along two principal types - that of d'Arsonval and that of Tesla - with in connection or combination with them, a third instrument, the resonator of Oudin.
Universal tomograph (origine Massiot France). This tomograph had a posterior version when the production Massiot became Philips Medical System. In a iron sheet construction this table was lighter than the first one (1947) in Holster, with a mass of 2500 kg! Professor Cornelis had the same equipment. He headed the neuro-radiology department in the academic hospital of the university of Louvain in the nineteen sixties. In addition to images of the skull taken from different angles, a large number of tomographs were produced with the "Polytome", an instrument developed by Philips. With the injection of contrasting agents such as "Lipiodol ® " images could be produced of the spinal marrow (myelographs), the brain (encephalographs) and arteries (arteriographs). A built in cassette device developed by the firm De Man allowed an easy switch of the radiographic parameters to optimise the imaging of different tissues. Note that in those days radiographic pictures were developed manually.
In the museum we display the first scanner (the sixth in the world) installed in 1974 in Belgium (city of Charleroi) in professor M.COLLARD's ( 1934 - ) department (ULB). A computer is used to store the subsequent tomographic images, improve or color the images electronically and reproduce the images in sequence afterwards. It results in in-depth images of the various body tissues allowing the diagnosis of lesions and the follow-up of applied medication and treatments. Linking computer and tomograph was achieved during the research work, carried out in the seventies in England by G.HOUNSFIELD and A.CORMACK. Their work was sponsored by the firm E.M.I., producer of the very successful records of the "Beatles". The computer had been developed during World War II for deciphering the coded messages of the German and Japanese armies.
