Photomultiplier tube (PMT)-based scintillation cameras are predominant in molecular imaging but have the drawback that position estimation is severely degraded near the edges (dead edge effect). This leads to sensitivity losses and can cause severe p

Convolutional neural network based attenuation correction for 123I-FP-CIT SPECT with focused striatum imaging

Autor: Marlies C Goorden, Freek J. Beekman, Yuan Chen

Publikováno v: Physics in Medicine and Biology, 66(19)

SPECT imaging with 123I-FP-CIT is used for diagnosis of neurodegenerative disorders like Parkinson’s disease. Attenuation correction (AC) can be useful for quantitative analysis of 123I-FP-CIT SPECT. Ideally, AC would be performed based on attenuat

SPECT and SPECT/CT

Autor: Freek J. Beekman, Brian Hutton, Marlies C Goorden

Single photon emission computed tomography (SPECT) and SPECT-CT are widely used in clinical practice, mostly based on rotation of planar gamma cameras. Tomographic images are reconstructed mainly using iterative algorithms that permit use of flexible

EXIRAD-HE: Multi-pinhole high-resolution ex vivo imaging of high-energy isotopes

Autor: Minh Phuong Nguyen, Marlies C Goorden, Freek J. Beekman

Publikováno v: Physics in Medicine and Biology, 65(22)

We recently developed a dedicated focusing multi-pinhole collimator for a stationary SPECT system that offers down to 120 µm (or 1.7 nL) spatial resolution SPECT images of cryo-cooled tissue samples (EXIRAD-3D). This collimator is suitable for imagi
