Kok-Tee was born in Singapore, the third child of Khaw Kai-boh and Tan Chwee Geok. She came to the UK for secondary school initially at Westonbirt and then at Marlborough College. She followed her brother Chay-Tee (B2 1967-71) to study medicine at Girton College, Cambridge with her clinical studies at Westminster Medical School.
She qualified from Cambridge in 1979 and became a consultant radiologist at Ealing Hospital moving after two years to St George’s Hospital, Tooting. She specialised in breast screening and ultrasound. She was a popular member of the department and became an educational supervisor for the radiology trainees.
In 2005 while organising the scientific programme of the British Medical Ultrasound Society in Manchester she suffered an acute subarachnoid haemorrhage. She was treated at Hope Hospital, Salford as an emergency with coil embolization of the middle cerebral artery followed by craniotomy and evacuation of haematoma. She suffered devastating paralysis of her right side and loss of speech. After three months of rehabilitation at Queen Square, she eventually made a remarkable recovery and after a year she began to work in the Prints and Drawings Room at Tate Britain which she continued up until the covid pandemic.
She suffered a catastrophic spinal cord injury after an accidental fall down the stairs in unfamiliar surroundings while visiting relatives and died at the Royal London Hospital on the 15th November 2022. She will be remembered for her generosity and kindness to others as well as her loud laugh, a wicked sense of humour and her smile which always lit up the room.
