54. A multi-axes gantry system for total-body J-PET/CT scanner

Tevfik Kaplanoglu

Introduction
Conventional PET/CT systems acquire images sequentially along a single axis using a moving patient table, typically within one or two adjacent gantry enclosures. Although whole-body imaging is feasible in this configuration, it requires multiple discrete bed positions and is therefore more susceptible to motion-related artefacts than total-body approaches. In addition,...

47. Studies of attenuation and detector geometry effects in two- and three-gamma positronium decays towards 3γ/2γ imaging using the Total-Body J-PET tomograph.

Conventional Positron Emission Tomography (PET) relies on the detection of two back-to-back 511 keV photons originating from electron-positron annihilations. However, about 40 percent of annihilations occur via positronium formation, including ortho-positronium (o-Ps) decays into three photons. The features of positronium, including its lifetime and the ratio of 3γ to 2γ annihilations (3γ/2γ),...

6. From image to video in Total-Body PET: Maximum-Likelihood Motion and Activity (MLMA) reconstruction

The advent of long axial field-of-view (LAFOV) PET has enabled simultaneous imaging of all organs with substantially higher sensitivity. However, motion remains an issue that degrades image quality, as the sensitivity of LAFOV-PET is insufficient to mitigate fast irregular motion at the subsecond timescale. We therefore propose to correct for motion in LAFOV-PET at high frequency (2 Hz) by...

33. DSAC: A Novel CT-less Attenuation Correction Approach for Cost-Effective Plastic Scintillator based Total-body PET

Satyam Tiwari

Background: The development of Total-Body PET (TB-PET) based on plastic scintillators, such as J-PET [1,2], offers a longer axial field-of-view and cost-effective framework for whole-body imaging. This technology also enables advanced applications like positronium imaging of the human brain [3]. The necessity of an external CT scanner for attenuation correction (AC) limits the benefits of...

29. High throughput imaging with Walk-Through-PET

Stefaan Vandenberghe

14/05/2026, 15:05

The Walk-Through PET (WT-PET) is an innovative approach to Positron Emission Tomography imaging that rethinks both system geometry and patient workflow. Unlike conventional cylindrical PET scanners that require patients to lie still on a moving bed, the WT-PET uses two vertically aligned flat detector panels positioned on either side of a standing patient. This design introduces a more open...
