Radiation Physics Analysis (RaphyA) is the research lab in the Department of Radiation Convergence Engineering at Yonsei University (Mirae Campus) in Wonju, Korea. RaphyA focuses on radiation convergence engineering technology, conducting research across various medical and radiation safety applications.

Our primary research areas include radiation therapy, radiation detection, radiation imaging, radiation dose evaluation, nuclear nonproliferation and safeguards. Our key technique include Monte Carlo simulation (Geant4, MCNP, PHITS, TOPAS, etc.), demand-based radiation detector development, AI based data analysis, exposed dose analysis, etc. The recent research topics are as follows.

1) Medical Physics

In-vivo patient dose verification with prompt gammas in particle therapy

Validity evaluation of brand new eye shield using Monte Carlo methods

Integrated C-arm CT and SPECT imaging system for internal source tracking

Conversion program from tetrahedral-mesh phantoms to DICOM data set for side effect reduction

2D dynamic multileaf collimator to improve treatment quality of the intensity-modulated radiation therapy

2) Safety and Security
