  1. 70. CT Synthesis in the Head & Neck Region for PET/MR Attenuation Correction: an Iterative Multi-atlas Approach

    In this work, we propose to tackle the problem of attenuation correction in the head & neck by synthesising CT from MR images using an iterative multi-atlas approach. The proposed method relies on pre-acquired T2-weighted MRI and CT images of the neck. For each subject, the MRI is non-rigidly mapped to the CT. To synthesise a pseudo CT, all the MRIs in the database are first registered to...

  2. 87. Simultaneous Reconstruction of Attenuation and Activity in ToF PET/MRI with Additional Transmission Data

    3 - Advances in MR-PET and MR-SPECT software and quantification
    Talk
    In Time-of-Flight PET/MRI systems accurate attenuation correction, based on the MRI image, is not straight forward. An alternative is attenuation correction based on emission data only. This is for instance done by simultaneous reconstruction of attenuation and activity with the MLAA algorithm, but the method as originally proposed has certain limits. The attenuation can only be determined up...

  3. 95. Imaging the Attenuation Coefficients of Positron Beams in Matter: Positron Attenuation Tomography
    Charles Watson (Siemens Healthcare)

    2 - Advances in MR-PET instrumentation: systems
    Talk
    A new positron annihilation imaging modality is described that enables non-destructive measurement of the linear attenuation coefficients (LACs) of positron beams in heterogeneous materials. This positron attenuation tomography (PAT) technique utilizes a positron emission tomography (PET) system embedded within a uniform static magnetic field, such as is found in integrated PET/MRI scanners. ...
