    Attenuation correction (AC) and scatter correction (SC) are essential in PET for accurate tracer quantification. Current AC methods use CT scans to derive AC factors but CT-based AC introduces extra radiation and can lead to artefacts due to spatial mismatch between PET and CT. Single scatter simulation is widely used for SC but is sensitive to errors in the attenuation map and relies on...

    Oral

    The evolution of high-resolution total-body (TB) PET/CT has expanded dynamic PET applications, yet the temporal resolution gap between PET and CT presents challenges for quantitative accuracy. Organ segmentation from CT exacerbates errors in kinetic modeling. This study aims to utilize enhanced anatomical details from TB PET for attenuation (AC) and scatter correction (SC), incorporating...

    Poster

    Long axial field of view (LAFOV) PET scanners enables measurements in the aorta or similar arteries with high time resolution which can used for definition of input functions to obtain the blood concentration as a function of time directly from reconstructed images.
    Here we present the application of a novel model-based recovery coefficient (RC) for partial volume correction to obtain...

    Oral

    The introduction of the Dual Flat Panel Walk-Through Total Body PET (WT-TB-PET) scan system has revolutionized imaging procedures, albeit presenting challenges stemming from patient motion while standing upright. Understanding motion patterns is pivotal for optimizing image quality and diagnostic accuracy. This study aims to analyse subject motion within the designed mock-up for the WT-TB-PET...

  5. 97. Estimation of the sensitivity for quantum entanglement imaging with total-body J-PET

    Total body imaging
    Oral

    In positron emission tomography, the density distribution
    of electron-positron annihilations in the patient's body
    is reconstructed based on the measurement of the time and position
    of the annihilation photon's interactions in the detection system.
    In this study, we demonstrate that J-PET scanner based on plastic scintillators
    enables the effective application of polarization of...

  6. 32. openSSS: open-source custom geometry and total-body PET scatter correction
    Rodrigo José Santo
    Total body imaging
    Oral

    Scatter correction is essential for quantitative and accurate time-of-flight (TOF) PET imaging. However, scatter estimation algorithms for total body and other custom geometries are not available in open-source libraries. To this end, we have developed an open-source implementation of the TOF-aware single-scatter-simulation (SSS) algorithm (openSSS). It is validated on the NEMA phantom and the...
