About

Piroska Kallos-Balogh is a leading researcher in medical imaging, specializing in the development and validation of phantoms for Positron Emission Tomography (PET). Her primary research areas include PET imaging methodology, radiomics, and image quality assurance. Dr. Kallos-Balogh’s most significant contribution is the invention of the "activity painting" phantom technique, which allows for the creation of highly reproducible phantoms with arbitrary, heterogeneous activity distributions. This breakthrough directly addresses a critical need in radiomics—the need for realistic, standardized test objects to evaluate the robustness of quantitative imaging biomarkers. Her foundational 2019 paper on this technique has garnered 10 citations, establishing a new tool for the field. Building on this, her 2024 multicentric study (5 citations) advanced the method to simulate arbitrary lesions within a radioactive background, enabling a rigorous, multi-center assessment of PET-based radiomics feature reproducibility. This work is pivotal for translating radiomics into reliable clinical practice. Dr. Kallos-Balogh’s innovative phantom solutions are essential for standardizing PET imaging research and improving the reliability of quantitative image analysis.
