This research explores “three-gamma PET,” a method that uses rare but information-rich gamma-ray events normally ignored by traditional PET imaging. By capturing and reconstructing these events with a custom 8π spectrometer, the project shows that three-gamma PET could improve accuracy, reduce scan time, and lower radiation dose, offering better diagnostics for cancer patients.

The talk highlights how biology involves unseen interactions and how distinguishing living from dead microorganisms is essential. Using the chemical PMA (propidium monoazide), researchers can identify active pathogens and reduce misinterpretation in diagnostic tests, especially for viruses that cannot be grown in labs. This technique helps improve diagnostics, guide treatments, and advance microbiological research.
