Friday, 23 January 2026
Doctoral candidate and lecturer in the Medical Imaging and Therapeutic Sciences Department, Gerhardus Koch, recently returned from an enriching international doctoral research exchange programme in Portugal.
Koch said the two-month programme at the Polytechnic Institute of Porto was “a truly unforgettable, once-in-a-lifetime opportunity”.
His research is titled: Individual patient radiation dose tracking guidelines for the South African healthcare system.
“It involves tracking the cumulative ionising radiation dose received by individual patients during medical imaging examinations throughout their lifetime. The purpose of maintaining such a record is to facilitate the early identification of individuals who are presumably at risk of developing radiation-induced injuries and cancers, thereby enhancing and promoting the justification and optimisation principles associated with patient radiation safety. Based on my research, I developed a model to guide the implementation of individual patient radiation dose tracking in South Africa.”
He said the experience has seen him grow personally and professionally.
“I expanded my professional network, formed lasting connections, and had the opportunity to share my research with international colleagues. The experience further led to the conception of a brand-new research project, which we are currently working on.
“This experience reinforced the importance of international research collaboration, scholarly mentorship, and adaptability. I am truly grateful to have had this opportunity and wish to thank our Head of Department, Dr Florence Davidson, for her encouragement, continued support and motivation.”
