Catterall is recognised across the world for her pioneering work in
neutron therapy. In 1943, she completed her initial training as a physiotherapist before deciding to re-train as a doctor. In the 1960s Catterall gained international attention for her work at
Hammersmith Hospital using an early 5
MeV cyclotron for neutron therapy treatment. She worked at Hammersmith Hospital until 1987, and wrote articles for medical journals during this period. In 1978 Catterall gave a guest lecture at the
Fermi National Accelerator Laboratory in Illinois. By 1982, the Cyclotron Unit at Hammersmith Hospital was at risk of closure, and Catterall was offered a job in the United States of America. Catterall was a member of the
British Institute of Radiology,
Royal College of Radiologists and a Fellow of the
American College of Radiology. In 1982, Catterall was awarded an honorary degree by
Durham University as part of their 150th anniversary events. == Sculpture ==
