AI-Assisted 3D Microscale Mesh Models of Human Lungs from Iodine-Stained Serial-Sectioned Histology Images and Their Dosimetry Applications

Authors: John P. Aris, Wesley E. Bolch, Robert Joseph Dawson, Bonnie N. C. President, Yitian Wang

Affiliation: Johns Hopkins University, University of Florida

Abstract Preview: Purpose: Generation of a mesh-based microscale lung model is essential for accurate dosimetry analysis. Lungs exchange air with the environment and may be exposed to alpha-particle-emitting radionucli...

Addressing Radionuclide Decay Complexities in Targeted Alpha Therapy: A Computational Approach.

Authors: Denis Bergeron, Ryan P Fitzgerald, Ravneet Kaur, Rao Khan

Affiliation: John Hopkins University, NIST Radiation Physics Division, Howard University, National Institute of Standards and Technology

Abstract Preview: Purpose: There is growing interest in short-lived alpha-emitting radionuclides for cancer therapy due to their ability to selectively target and destroy cancer cells while sparing healthy tissue. Howe...
