Dedicated brain PET system of PET/MR for brain research.
Institute of Medical Physics, Department of Engineering Physics, Tsinghua University, Beijing, China This work is to replace PET ring in human brain PET/MR system with a dedicated wearable PET insert, aimed at improving both patient feasibility and system performance for brain imaging. The designed PET/MR system includes two parts: the inside parts, including a radio frequency (RF) coil and PET...
متن کاملDesign study of dedicated brain PET with polyhedron geometry.
BACKGROUND Despite being the conventional choice, whole body PET cameras with a 76 cm diameter ring are not the optimal means of human brain imaging. OBJECTIVE In fact, a dedicated brain PET with a better geometrical structure has the potential to achieve a higher sensitivity, a higher signal-to-noise ratio, and a better imaging performance. METHODS In this study, a polyhedron geometrical d...
متن کاملA dedicated neonatal brain imaging system
PURPOSE The goal of the Developing Human Connectome Project is to acquire MRI in 1000 neonates to create a dynamic map of human brain connectivity during early development. High-quality imaging in this cohort without sedation presents a number of technical and practical challenges. METHODS We designed a neonatal brain imaging system (NBIS) consisting of a dedicated 32-channel receive array co...
متن کاملPerformance evaluation of a novel brain-dedicated SPECT system
Background: Single-photon emission computed tomography (SPECT) imaging is an important diagnostic tool for the early detection of the loss of nigrostriatal dopaminergic neurons in Parkinson’s disease (PD) and similar neurodegenerative disorders. Visualization and quantification of dopamine transporter (DAT) binding in the striatum is an established diagnostic tool to detect nigrostriatal dopami...
متن کاملDesign and performance evaluation of spheroid geometry for brain PET scanner using Monte Carlo modeling
Introduction: There has been a curiosity about the spheroid geometry for PET scanners developments since several years ago, therefore in this study, we are aiming to evaluate the performance of this geometry and compare its performance with cylindrical geometry using Monte Carlo simulation. Methods: We simulated a spheroid geometry with a radius of 199 mm...
