And Rebecca, 24, won first prize for her presentation which examined the incorrect classification of red dot markers on wrist radiographs taken in accident and emergency departments.
Harry, 26, took third prize for his research looking at the accuracy of ultrasound in detecting paediatric fractures.
Senior Lecturer in Diagnostic Radiography at 海角直播 Dr Philip Cosson was research supervisor for three of the four students. He said: 'This event is one of the most prestigious research poster competitions we have in the field of radiography.
'To have four students from 海角直播 present their work is a fantastic achievement in itself, but to also come away with first and third prizes shows that the work we are doing is recognised as having a real impact in the radiography profession.
'All the students who presented their work in Helsinki are now working as professional radiographers after completing their courses at 海角直播.'
Rebecca, who is working at the Queen Elizabeth Hospital in Gateshead as a Diagnostic Radiographer, said the event has given her additional inspiration in her career and research.
She added: 鈥淚t has really motivated me and I would like to extend my studies into a PhD when the opportunity arises.
'To win first prize was unbelievable, especially as the standard of work was so high.
'In my research I established five anatomical/pathological predictors for error in wrist fracture identification; these may go on to inform image interpretation training and contribute to the wider knowledge base surrounding the 'red dot' radiographer abnormality detection scheme. It is great to know that the work I have carried out could make a real difference within the profession.' Harry, who is working as a Diagnostic Radiographer in Oxford at the John Radcliffe Hospital, said: 'It is amazing to know that people from so many countries were interested and impressed by my research. Coming third in such a prestigious competition was not something I was expecting - though I am extremely proud.'
The International World Congress of Radiography is set up by the International Society of Radiographers and Radiologic Technologists (ISRRT) and is an ideal way for students to liaise with some of the world鈥檚 top scientists and professionals.
