Journal ArticleDOI
GPU computing in medical physics: a review.
Guillem Pratx,Lei Xing +1 more
TL;DR: The authors review the basic principles of GPU computing as well as the main performance optimization techniques, and survey existing applications in three areas of medical physics, namely image reconstruction, dose calculation and treatment plan optimization, and image processing.
Journal ArticleDOI
X-Ray Luminescence Computed Tomography via Selective Excitation: A Feasibility Study
TL;DR: Computer simulations exploring the feasibility of imaging small objects with X-ray luminescence computed tomography, such as research animals, are presented.
Journal ArticleDOI
Development and MPI tracking of novel hypoxia-targeted theranostic exosomes.
TL;DR: An exosome platform that can target regions of tumor hypoxia and that can be monitored in vivo using magnetic particle imaging (MPI) is developed and the therapeutic efficacy of Olaparib-loaded exosomes was demonstrated by increased apoptosis and slower tumor growth in vo.
Journal ArticleDOI
Synthesis and Radioluminescence of PEGylated Eu3+-doped Nanophosphors as Bioimaging Probes
Conroy Sun,Guillem Pratx,Colin M. Carpenter,Hongguang Liu,Zhen Cheng,Sanjiv S. Gambhir,Lei Xing +6 more
TL;DR: High-energy radiation, currently employed in medical imaging modalities, such as X-ray computed tomography or positron emission tomo graphy (PET), may also be used to excite NIR-emitting radioluminescent nanophosphors (RLNPs) for bioimaging.
Journal ArticleDOI
Tomographic molecular imaging of x-ray-excitable nanoparticles
TL;DR: A prototype XLCT system is built and imaging in an optically diffusive medium shows that imaging performance is not affected by optical scatter; furthermore, the linear response of the reconstructed images suggests that XLCT is capable of quantitative imaging.
