PET-based geometrical calibration of a pinhole SPECT add-on for an animal PET scanner.
We developed SPECT imaging capability on an animal PET scanner to provide a cost effective option for animal SPECT imaging. The SPECT add-on sub-system was enabled by mechanically integrating a multiple-pinhole collimator in the PET detector ring. This study introduces a method to calibrate the geometrical parameters of the SPECT add-on using the PET imaging capability of the scanner. The propo...
متن کاملMonte Carlo simulations of a small-animal PET scanner
The work here presented analyzes the performances (in terms of scatter fraction, spatial resolution, sensitivity, image quality) obtained from a 10detectors small-animal PET, simulated via Geant4 Application for Emission Tomography (GATE), in comparison with other designs studied in previous works. Particular attention is given to the comparison with the 12-detectors miniPET II, already built a...
متن کاملFeatures of the NIH atlas small animal PET scanner and its use with a coaxial small animal volume CT scanner
ATLAS (Advanced Technology Laboratory Animal Scanner), a small animal PET scanner designed to image animals the size of rats and mice, is about to enter service on the NIH campus in Bethesda, Maryland. This system is the first small animal PET scanner with a depth-ofinteraction capability and the first to use iterative resolution recovery algorithms, rather than conventional filtered back proje...
متن کاملPerformance evaluation of an Inveon PET preclinical scanner.
We evaluated the performance of an Inveon preclinical PET scanner (Siemens Medical Solutions), the latest MicroPET system. Spatial resolution was measured with a glass capillary tube (0.26 mm inside diameter, 0.29 mm wall thickness) filled with (18)F solution. Transaxial and axial resolutions were measured with the source placed parallel and perpendicular to the axis of the scanner. The sensiti...
متن کاملThe imaging performance of a LaBr3-based PET scanner.
A prototype time-of-flight (TOF) PET scanner based on cerium-doped lanthanum bromide [LaBr(3) (5% Ce)] has been developed. LaBr(3) has a high light output, excellent energy resolution and fast timing properties that have been predicted to lead to good image quality. Intrinsic performance measurements of spatial resolution, sensitivity and scatter fraction demonstrate good conventional PET perfo...
