EARLY-CAREER RESEARCHERS IN MEDICAL APPLICATIONS @ CERN – SHORT TALKS

About

Discover how technological advances for high-energy physics have become essential tools for modern medicine.

This series of short talks is given by Early-Career Researchers working on projects related to diverse medical applications that arise from technology developed at CERN and in high-energy physics.

In this seminar 2 Researchers (one, an assistant professor at UNIMIB and the other, a CERN doctoral student) will share their work on TOF-PET.

Time-of-Flight (TOF) Positron Emission Tomography (PET) uses the time difference between the two annihilation photons to improve the Signal-to-Noise-Ration (SNR) compared to standard PET. A 10ps full-width-half-maximum (FWHM) coincidence time resolution (CTR) would mean a huge improvement in the SNR and spatial resolution, with an uncertainty of only 1.5mm. A CTR of 10ps would also increase effective sensitivity, which means earlier diagnosis and reduced patient exposure time to ionizing radiation, making this diagnostic test also possible for pregnant women and children.

The aim of our KT/MA project is to develop TOF-PET modules toward 50ps time resolution based on heterostructure concept. Heterostructured scintillators rely on the combination of two materials with complementary properties (e.g., high stopping power and ultra-fast scintillation kinetics) to take advantage from both. In this talk, we show the validity of these approach and the investigation of the fundamental properties of these structures.
