Although the discipline was at that time embryonic, he also established the first Canberra diagnostic ultrasound service there in 1976 and from humble beginnings this was developed into a comprehensive, state of the art centre. These were exciting years when practice outstripped the ability of the books to keep up and many interventional and other techniques were pioneered.

He became a foundation diplomat of the Diploma of Diagnostic Ultrasound and for many years was an examiner for the Diploma. In 1988 he received the uncommon distinction of an Honorary Fellowship of the Australasian College of Radiologists for services to Ultrasound.

Patient contact has always been an important stimulus for Fred, and he has now been seeing Thyroid patients in consultation at hospital and private clinics since 1969. Having all the investigative tools at his finger-tips, most patients are fully evaluated in a single visit.

Away from work, he tends his orchids in Sydney and writes an orchid column. Working half time has enabled him to extend his professional life and enjoy it more. And he intends to keep working for some time yet!
