Purpose:Cone beam X‐ray luminescence computed tomography (CB‐XLCT), which aims to achieve molecular and functional imaging by X‐rays, has recently been proposed as a new imaging modality. However, the inverse problem of CB‐XLCT is seriously ill‐conditioned, hindering us to achieve good image quality. In this work, a novel reconstruction method based on

Purpose: FDG‐PET is increasingly used in the gross tumor volume (GTV) definition of lungcancer patients undergoing radiotherapy. There is currently no reliable technique for segmenting GTV using PET, mainly due to varying background levels of the mediastinal blood pool and normal lung.

Scalability of Gaussian 03 on SGI Altix: The Importance of Data Locality on CC-NUMA Architecture
2009Performance anomalies when running Gaussian frequency calculations in parallel on SGI Altix computers with CC-NUMA memory architecture are analyzed using performance tools that access hardware counters. The bottleneck is the frequent and nearly simultaneous data-loads of all threads involved in the calculation of data allocated in the node where the ...

Efd-C(13)03/44 Bayesian Tomography Of Soft X-Ray And Bolometer Systems Using Gaussian Processes
2013A new Bayesian tomographic method for soft-X and bolometer diagnostic systems has been developed. The method is non-parametric in the sense of using Gaussian processes to model ,the underlying emissivity distribution, and the regularization of such a model becomes defined by a multivariate normal distribution at the points where the emissivity ...
