4. Breast PET Insert in a Whole-Body PET/MRI: Attenuation Effects and Resolution Recovery

Hong Phuc Vo (Institute of Medical Engineering, Universität zu Lübeck)

We are developing a breast PET insert operating in combination with a whole-body (WB) PET/MRI scanner to improve the detectability of small lesions and early metastases. However, additional detector material can introduce attenuation-induced artifacts that degrade WB-PET image quality. We implemented a joint reconstruction with attenuation correction to explicitly handle the different types...

40. A long axial field-of-view PET insert design based on dual-ended side-readout for simultaneous PET and metabolic MRI in the META-scan system

Introduction:
The META-scan, an ultra-high-field Magnetic Resonance Imaging (MRI) scanner developed to visualize metabolic processes in vivo in the entire human body, can potentially be used to study acute metabolic effects and fast interactions between the brain and other organs, such as the liver, gut, heart, and kidneys. However, due to its low sensitivity, studies involving drug...

17. 3D-printed multimodality phantoms for quality control procedures in TBPET, PSMR and FTMI systems.

Background:

Total Body PET (TB-PET) and PET/SPECT combined with MR (PSMR) systems, and Fast Timing in Medical Imaging (FTMI) have changed the field of molecular imaging. The technical improvements conveyed by these next-generation systems offer a unique opportunity to develop new scanning protocols, enabling earlier diagnosis and more precise, low-dose whole-body imaging through...

28. Multiple Emission Tomography: GPU-Accelerated LM-OSEM Reconstruction for Compton Events

Matteo Neel Colombo (Universita & INFN, Milano-Bicocca (IT))

13/05/2026, 15:30

The Multiple Emission Tomography (MET) detector is a single-layer ring of scintillator modules, that can work in Compton camera mode on top of the conventional "PET" one. Provided that a fast reconstruction that can exploit its high sensitivity can be developed, it is expected to enable imaging of exotic nuclei with high-energy gamma emissions. In this work, we present a list-mode Ordered...

18. The MERMAID Project: Current Developments and Future Directions

Ms Rebecca Kantorek (Universität zu Lübeck)

13/05/2026, 15:50

The MERMAID (Multi-Emission Radioisotopes – Marine Animal Imaging Device) project aims to develop a dedicated PET/CT scanner for functional imaging of adult zebrafish. The system consists of four rotating detector modules arranged in pairs and provides a field of view (FOV) of 2.5 cm (diameter) and 6 mm (axial length). To extend the axial FOV, a motorized stage is integrated for bed placement...
