    03/07/2023, 16:35
    Contributed e-poster

    Metal halide perovskite (MHP) is a promising candidate material for the next-generation X-ray detector, particularly due to the excellent charge transport properties.
    However, a mobility-lifetime product of electrons and holes as well as detector stability are compromised by high ionic conductivity under an external electrical field.
    To resolve this issue, we explore charge transport...

    Contributed e-poster

    Hybrid lead halide perovskites are a promising candidate for a new generation of highly sensitive direct-converting detectors for medical X-ray imaging.

    03/07/2023, 16:35
    Contributed e-poster

    A major thrust of medical X-ray imaging is to minimize the X-ray dose acquired by the patient, down to single-photon sensitivity. Such characteristics have been demonstrated with only a few direct-detection semiconductor materials such as CdTe and Si; nonetheless, their industrial deployment in medical diagnostics is still impeded by elaborate and costly fabrication processes. Hybrid lead...

    04/07/2023, 16:35
    Contributed e-poster

    Ultra High Energy Cosmic Rays (UHECRs) above 100 PeV could be detected from space by pointing to the Earth's limb when the optical emission from extensive air showers (EAS) is produced. A space-born experiment could also play a key role in the multi-messenger field if the detection of Earth-skimming neutrinos will be ensured. The validation process for this detection of rare UHE events goes...

    Contributed e-poster

    Pushing the limits of the readout system in standard ToF-PET scanners will improve tomographic image reconstruction quality. Scintillation crystals optically coupled to photo-detectors, together with fast readout electronics, are the key elements to improve Coincidence Time Resolution (CTR).

    Positron Emission Tomography (PET) imaging constitutes the molecular imaging technique of excellence and is used to evaluate a radio-tracer uptake by an organ. To obtain PET images, patients are injected with radioisotopes that decay inside the patient body emitting a positron that subsequently annihilates with a core electron of the patient body, emitting two opposite 511 keV gamma-rays. PET...
