    Dr Marc-Antoine Verdier (IJCLab - Université Paris Cité)
    25/04/2023 09:40

    The main experimental challenging developments in positron emission tomography (PET) are currently focusing on improving the sensitivity either by pushing the time of flight (ToF) performances or extending the axial field of view. As an alternative the use of 3γ detection capability enables several extra advantages, including the possible enhancement of the ToF information to better locate the...

    M. Adrien Paillet (BioMaps-Université Paris-Saclay-SHFJ-CEA)
    25/04/2023 10:00

    PET imaging is undergoing continuous improvements thanks to developments of new
    detection approaches, new designs and new electronic chains. For example, whole-body
    scanners' geometries, advances in detectors' time resolution, and improvements in TOF image reconstruction are hot topics for dynamic acquisitions.
    Monte Carlo GATE simulations can be used to quantify the impact of these...

    25/04/2023 11:30

    The correlation of molecular neuroimaging and behavior studies in the preclinical field is of major interestto unlock progress in the understanding of brain processes and assess the validity of preclinical studies in drug development. However, fully achieving such ambition requires being able to perform molecular images of awake and freely moving animals whereas currently, most of the...

    Mlle Sarah Blind (CRAN, BioSiS, Université de Lorraine)
    25/04/2023 14:00

    As part of the european project RXNanoBRAIN, the image-guided radiation therapy and the radiosensitization by Gadolinium and Bismuth hybrid nanoparticles are investigated for the treatment planning of the glioblastoma brain tumor. In this context, we performed Gate Monte Carlo simulations to assess the deposited dose in clusters of Bismuth-Gadolinium nanoparticles in U251 glioblastoma cells....

    M. Mustapha Assalmi (Universite Mohammed First)
    25/04/2023 15:00

    In this study, we aimed to investigate the effect of flattened filter on dose distribution in a heterogeneous phantom using Monte Carlo simulation. The GATE Monte Carlo code was used to simulate photon beams of 6 MV in a heterogeneous phantom consisting of lung and breast tissues. The electrons accelerated by 6MV in flattened and unflattened modes were configured in Gaussian parameters. The...

  14. 46. New Digitizer in Gate 9.3
    Olga KOCHEBINA
    25/04/2023 16:30

    Digitizer in the current GATE plays an important role for PET, SPECT, CT, Compton Camera detectors or more generally for imaging system modeling. It simulates the response of the photodetection components by a sequence of analytical models. Digitizer takes as input a list of interactions, Hits, within a crystal or detector element and generates digital pulses. In a digitization, the last one...

  16. 55. Dose activities boosted with AI from lab LaTIM
    Dr Jing Zhang (LaTIM, UBO)
    26/04/2023 09:00

    Dose distribution is simulated by Monte Carlo (MC) method generally. However, due to its data dependency, complex model, long computational time, instead, our work utilize AI models to predict dose distribution in real time, which is a series of mathematical operations that fit on a wide range of data and flexible in handling new cases. Furthermore, this work compares the MC simulation...

    In Proton Therapy Center in Prague we have developed a method for patient based quality assurance. Our project is based on Monte Carlo (MC) and is built on Gate. By means of MC, dose computational algorithms of local treatment planning systems XiO 5.1 (Elekta, Sweden) and RayStation 11B (RaySearch, Sweden) can be verified as MC method provides the highest calculation accuracy. It provides...

    The PETITION PET detector, has been developed for in-beam use at Gantry 2 at PSI,
    with an open ring design allowing for measurement of patient activation both during and
    following proton therapy treatment. Tools for time resolved simulations of patient
    treatments have been implemented using Gate. Intra-field imaging in the dead time

  21. 53. Towards GATE 10 for ion beam therapy applications
    Mlle Martina Favaretto (MedAustron GmbH)
    26/04/2023 11:10

    In ion beam therapy, Monte Carlo (MC) particle transport simulations are being increasingly used to perform independent dose calculation (IDC) for quality assurance in light ion beam therapy. In practice, IDC consists in recomputing the dose in the patient starting from the treatment plan specifications, with a Monte-Carlo engine. The results can be compared with the planned dose as a...

  22. 56. Validation of TEPCActor for slab detectors in microdosimetry
    Mlle Sandra Barna (Medizinische Universität Wien)
    26/04/2023 11:30

    Monte Carlo (MC) simulations of microdosimetric spectra are available for different codes, detectors and particle types/energies. While good results can be achieved if the detector geometry is modelled in detail [1, 2], a simpler approach can also result in very good agreement.
    At five positions along a 238.6 MeV/u carbon ion pencil beam, spectra were collected using the Silicon MicroPlus...
