About

Nina-Sophie Schmidt-Hegemann is a radiation oncologist whose research focuses on precision and motion management in prostate cancer radiotherapy. Her work addresses a critical challenge in the field: ensuring accurate dose delivery to the prostate despite patient movement and external factors. Her most-cited study, "Prefraction displacement and intrafraction drift of the prostate due to perineal ultrasound probe pressure" (2017, 18 citations), systematically quantifies how ultrasound probe pressure can cause significant prostate displacement before and during treatment fractions. This contribution provides essential data for clinicians using ultrasound-based image guidance, helping them account for and mitigate these shifts to improve treatment accuracy. By characterizing both prefraction displacement and intrafraction drift, Schmidt-Hegemann’s research directly informs protocols for real-time motion management, reducing the risk of geographic miss and toxicity. Her work is particularly valuable for practitioners adopting non-ionizing imaging techniques, offering evidence-based guidance to enhance the precision of prostate radiotherapy. Through this focused investigation, she has made a practical impact on daily clinical practice, underscoring the importance of understanding mechanical interactions between imaging devices and target anatomy.
