Improved axial spatial resolution in positron emission tomography (PET) scanners will lead to reduced sensitivity unless the axial acceptance angle for the coincidences is kept constant. A large acceptance angle, however, violates assumptions made in most reconstruction algorithms, which reconstruct parallel independent slices, rather than a three-dimensional volume. Two methods of treating the axial information from a volume PET scanner are presented. Qualitative and quantitative errors…

Factors Affecting Accuracy and Precision in PET Volume Imaging

Volume imaging positron emission tomographic scanners with no septa and a large axial acceptance angle and good energy resolution are needed in order to use a high energy threshold to reduce the coincident scattered radiation.

Three-dimensional image reconstruction for PET by multi-slice rebinning and axial image filtering.

The reconstruction method makes use of all coincidence data acquired by high-sensitivity PET systems that do not have inter-slice absorbers to restrict the axial acceptance angle, making it well suited for dynamic and whole-body studies.

Positron Emission Tomography With A Large Axial Acceptance Angle: Signal-to-noise Considerations

A volume imaging PET scanner with a large acceptance angle, such as the PE"-PET, offers fine spatial sampling and resolution in three dimensions, and a high sensitivity because of the inclusion of

Figures of merit for comparing reconstruction algorithms with a volume-imaging PET scanner.

It is shown that the single-slice rebinning algorithm is a good compromise between sensitivity, speed, and accuracy when compared to standard two-dimensional reconstruction, and a 3D reconstruction with alpha = 9 degrees.

Effect of spatial behavior of scatter on 3D PET

In 3D positron emission tomography (PET), all the coincidence events can be collected to increase the sensitivity of signal detection. However, the sensitivity increase results in the enlargement of
