  • Godfrey Hounsfield
    Outstanding Contributions Over the Last 50 Years 50 Years of IOMP 1963-2013 Godfrey Hounsfield Sir Godfrey Newbold Hounsfield CBE, FRS was an electrical engineer, who was awarded the Nobel Prize for Physiology or Medicine for developing X-ray computed tomography (CT). Its introduction was a fundamental advance of the greatest importance to diagnostic medicine. His name is immortalised in the Hounsfield scale, a measure of electron density which is used in evaluating CT scans. In September 1939, Hounsfield joined the RAF as a volunteer reservist and worked as a radar mechanic instructor during the war. After the war he obtained a grant to study electrical and mechanical engineering at Faraday House in London and then joined the research staff of Electric and Musical Instruments (EMI) at their Central Research Laboratories to work on radar and guided weapons. He became interested in computers and led the team that built the UK’s first all-transistor computer: the EMIDEC 1100. In those days, transistors were much slower than valves. Hounsfield overcame this problem by using a magnetic core to drive the transistor. This led to transistors being used in computing earlier than would otherwise have been possible. Shortly after this, he began working on pattern recognition and became interested in developing a computer that could take Figure1. Hounsfield’s sketch for a CT scanner. measurements from X-rays at various angles to build up a three-dimensional picture of an object. Hounsfield’s first experimental system successfully scanned a pig’s brain in 1968. The scanning process took nine days and required two and a half hours to process the resulting 28,000 measurements on a high-speed computer.

  • Atkinson Morley Hospital
    72 YEARS OF THE NHS: ATKINSON MORLEY HOSPITAL Atkinson Morley Convalescent Hospital, Copse Hill c.1870. Built between 1867 and 1869, this was the first purpose built medical facility to be linked to an inner city hospital. It was constructed thanks to hotelier and former medical student, Atkinson Morley, to care for convalescent patients from St. George’s Hospital, Hyde Park. Morley had been a Governor at St. George’s and left money in his will to finance the new facility. Patients were transported between the two sites by two horse-drawn carriages - these were replaced by a 14 seat omnibus in 1888. Atkinson Morley Hospital, Copse Hill, c.1906 By 1901 the building was in a precarious state and the ceiling of the children's ward collapsed. The hospital underwent complete refurbishment and electricity was installed throughout. Patients recuperating in the open air, Atkinson Morley Hospital, c.1918. During the First World War, the hospital was converted to care for wounded servicemen - some of whom can be seen here, recuperating in day beds on the hospital balconies. By 1922 financial problems forced the hospital to close for a three month period. The interwar years witnessed its gradual evolution from a convalescence home to a fully functioning hospital, treating more acute cases including tuberculosis patients. Sir Wylie McKissock 1906 – 94 In 1939 the number of beds at the Atkinson Morley hospital was reduced to cut costs. This move was reversed during World War Two, when the hospital was needed to treat casualties and acute cases transferred from the Bolingbroke and St.

  • The Physician's Tale
    The physician’s tale Travels with the Medical Pilgrims 1928–2011 Foreword This is the third edition of accounts (Scribes’ Reports) of the Medical Pilgrims since the first volume was published in 1997 by RCP Publications. That first volume was collated by Clifford Hawkins. Sadly he died before finishing the task, which was completed by Alasdair Geddes and Robert Mahler. Subsequently, a further volume of eight Pilgrimages 1996–2003, edited by Robert Mahler was published in 2003 (see Editor’s note from that volume on page 159). Rather than producing a further update, Pilgrims agreed to a full compilation from 1928–2010 in a single volume which could then be made available on the internet and updated regularly. This contains 75 Scribe’s Reports (there were no meetings during the second World War and the first post war meeting was held at the London Hospital in 1948). The original purpose of the Medical Pilgrims was to visit centres of medical excellence and get to know leading continental physicians. Eight of the first ten Pilgrimages were to centres outside Great Britain and Ireland, seven to Continental Europe and one to America. Only three of the ten post war Pilgrimages were to Europe. However, although the pre-war pattern was temporarily re-established in the late 50s and 60s, the subsequent three decades saw 25 of 30 Pilgrimages within the UK and Ireland. From 2000, a more eclectic approach of earlier Pilgrimages has become established with an informal commitment to one in three Pilgrimages being undertaken outside the UK. The Medical Pilgrims are not an entity and there are no accounts to audit.
