Abstract

1381744 X-ray tubes PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 22 March 1972 [25 March 1971] 13418/72 Heading H1D [Also in Division H5] An X-ray source particularly suitable for the radiography of soft tissues, e.g. for mammography, includes an X-ray tube having an anode target which comprises ruthenium, rhodium, or palladium, together with a filter for the X-rayswhich may be either outside the tube, or constitute the tube window-which comprises one of these elements or silver. The double focus, rotatable anode, tube shown has a cathode 7 divided by a centre tapping 8, and an anode formed by a disc 17 of one of the above materials mounted in a molybdenum holder 13, the electron beam 11 from the split cathode being incident on the disc or the holder, and the emitted X-rays passing through the beryllium window 3 and the filter 21.
