Dosie™ adds modeling Interstitial Photodynamic Therapy (I-PDT)

International Photodynamic Association World Congress, 2019 (Boston, USA) – Simphotek announces a new addition to its simulation software Dosie™ - near real-time finite element (FE) solver that accurately simulates light intensity distribution for interstitial type PDT. The new module is integrated with Dosie photokinetics that allows to estimate delivered PDT dose and (reacted) singlet oxygen dose in minutes.

We report incorporating finite-element-based light propagation simulations with photokinetics of the light-activated drug (PS) to create a dosimetry system for light fluence rate, fluence, and induced fluorescence, in near real-time and in 3D, for PDT treatment in the clinic. Recent experiments in phantoms at Roswell Park Cancer Institute show excellent agreement with calculations. Future efforts will develop a novel hardware and software prototype platform with feedback and monitoring that integrates real-time light and PS dosimetry.
