12. A Mesh-Type Reference Computational Phantom Platform for Multi-Modality Monte Carlo Simulation in OpenGATE

Dr Jin Jegal (Korea Institute of Radiological and Medical Sciences, Department of Radiation Oncology, Seoul, Republic of Korea)

GATE workshop

Mesh-type Reference Computational Phantoms (MRCP) provide anatomically realistic tetrahedral organ structures, but their practical use in OpenGATE-based imaging and dosimetry simulations remains limited. In our previous work, a simplified tetrahedral phantom was imported using a tessellated solid-based workflow and evaluated with heart and body geometries. In this study, we extended the...

17. Toward Image Reconstruction of Realistic Breast Phantoms: Experimental Calibration of a GATE Model and Phantom Development for a dedicated Breast PET/MR Insert

Elnaz Olyaei (Werner Siemens Imaging Center, Department of Preclinical Imaging and Radiopharmacy, University of Tuebingen, Tuebingen, Germany)

GATE workshop

We are presenting the next steps of a simulation framework for a dedicated dual-layer, depthof-interaction (DOI)-capable breast PET insert integrated into the Siemens Biograph mMR
PET/MR system. This work combines two complementary steps, the experimental calibration
of the GATE detector model and the development of realistic, patient-derived breast phantoms,
both aimed at enabling...

15. Bridging Detector- and Scanner-Level Modeling: A New Actor for Ultrafast Modeling of Optical Photon Transport in Scintillation Detectors

Stephan Naunheim (University of California, Davis)

GATE workshop

Prototyping novel scintillation detectors and PET/SPECT scanners heavily relies on Monte Carlo simulations to inform hardware optimization and data-processing development. While optical photon simulations remain the gold standard for detector modeling and provide details on spatial, energy, and TOF resolution, they are extremely time-consuming because they track thousands of optical photons...

14. Dose point kernel characterization and ICRP-107 database validation in GATE v10 for targeted alpha therapy

Dr Matthew Strugari (Biomedical Imaging Research Group (GIBI230), Instituto de Investigación Sanitaria La Fe (IIS La Fe), Valencia, Spain)

12/11/2026 14:03

GATE workshop

Purpose: Targeted alpha therapy (TAT) offers high biological effectiveness, but image-based treatment verification and dosimetry remain challenging due to complex radionuclide decay schemes and the highly localized energy deposition of alpha particles. Dose point kernels (DPKs) can support voxel-based dosimetry by describing the spatial distribution of energy deposition around a...

13. A simplified reconstruction of Positron Emission Tomography image using Time of Flight simulated data in Gate 10

Marcin Balcerzyk (Bioaraba Health Research Institue)

12/11/2026 14:15

GATE workshop

Background: Ultrafast Time-of-Flight (TOF) information in Gate 10 simulations enables direct 3D PET reconstruction without scanner-specific modeling. Although such picosecond timing is not achievable in current detectors, simulated data allow exploration of idealized TOF regimes and rapid evaluation of prototype PET designs. Methods: The TOF-driven reconstruction assigns each...
