Imaging of weak-source distributions in LSO-based small-animal PET scanners.
UNLABELLED Lutetium oxyorthosilicate (LSO)- or lutetium-yttrium oxyorthosilicate (LYSO)-based PET scanners have intrinsic radioactivity in the scintillator crystals due to the presence of (176)Lu, which decays by beta-emission followed by one or more prompt gamma-ray emissions. This leads to intrinsic true counts that can influence the image when scanning low levels of activity. An evaluation o...
متن کاملAtlas-based attenuation correction for small animal PET/MRI scanners
Small animal PET/MRI scanners producing anatomically co-registered simultaneously-acquired images of morphology, function and metabolic activity have become available and are expected to have a huge positive impact on the pre-clinical imaging field. Attenuation correction (AC) necessary for accurate quantification of PET signals is challenging in these scanners because the measured anatomical m...
متن کاملSmall animal PET imaging.
Positron emission tomography (PET) is well established as an important research and clinical molecular imaging modality. Although the size differences between humans and rodents create formidable challenges for the application of PET imaging in small animals, advances in technology over the past several years have enabled the translation of this imaging modality to preclinical applications. In ...
متن کاملImproved dead-time correction for PET scanners: application to small-animal PET.
Pile-up and dead-time are two main causes of nonlinearity in the response of a PET scanner as a function of activity in the field of view (FOV). For a given scanner and acquisition system, pile-up effects depend on the material and size of the object being imaged and on the distribution of activity inside and outside the FOV, because these factors change the singles-to-coincidences ratio (SCR)....
متن کاملResolution Uniformity and Sensitivity of the NIH ATLAS Small Animal PET Scanner: Comparison to Simulated LSO Scanners Without Depth-of-Interaction Capability
Positron emission tomography (PET) scanners designed to image animals the size of rats and mice should possess simultaneously high and uniform spatial resolution and high sensitivity. ATLAS (Advanced Technology Laboratory Animal Scanner), a 6.0 cm diameter effective transverse field-of-view (FOV), 2 cm axial FOV ring-type research scanner seeks these goals by surrounding the animal with eightee...
