摘要:The correction of γ-photon attenuation in PET-MRI remains a critical issue, especially for bone attenuation. This problem is of great importance for brain studies due to the density of the skull. Current techniques for skull attenuation correction (AC) provide indirect estim...

摘要:The development of a reliable dose monitoring system in hadron therapy is essential in order to control the treatment plan delivery. Positron Emission Tomography (PET) is the only method used in clinics nowadays for quality assurance. However, the accuracy of this method is ...

摘要:Abstract(#br)The peripheral benzodiazepine receptor (PBR) is expressed by microglial cells in many neuropathologies involving neuroinflammation. PK11195, the reference compound for PBR, is used for positron emission tomography (PET) imaging but has a limited capacity to quan...

摘要:Objectives: One major obstacle to proper attenuation correction of the skull in PET-MR is the inability to detect the crystal component of cortical bone by 1H-MRI. Current techniques for skull attenuation correction in PET-MR (atlas-based and segmentation-based methods) prov...
