SEMINARIO: Time-of-flight PET – From pixels to blocks to whole-body system applications

Summary/Bio

This seminar will highlight recent advances in time-of-flight positron emission tomography (TOF-PET) and their impact on clinical imaging. Through precise digitization of time-of-flight information, PET imaging benefits from improved signal-to-noise ratio and enhanced effective sensitivity. While current clinical systems reach timing resolutions of around 180 ps, experimental work demonstrates that modern detector materials can achieve sub-100 ps performance. The integration of TOF-PET with large axial field-of-view (LAFOV) systems further increases geometric sensitivity, enabling new possibilities such as ultrafast dynamic imaging and low-dose imaging protocols, particularly beneficial for vulnerable patient populations.

Dr. Vanessa Nadig holds a PhD in physics from RWTH Aachen University. Following her doctoral work, she joined Siemens Healthcare Limited and King’s College London, where she focuses on translating advanced PET technologies into clinical applications. Her current work involves two whole-body PET/CT systems, contributing to the development of next-generation imaging capabilities.
