Digital tomosynthesis using a scanned projection radiographic system
"... Tomosynthesis, an imaging mode related to classical tomography, is designed to produce arbitrarily many tomograms through processing of an appropriate set of radiographs. This paper examines the applicability of digital radiography technology to this technique. In this approach, component radiograph ..."

Coil sensitivity encoding for fast MRI. In:
- Proceedings of the ISMRM 6th Annual Meeting,
, 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

the number of k-space samples is reduced is referred to as the reduction factor R. In standard Fourier imaging, reducing the sampling density results in the reduction of the FOV, causing aliasing. In fact, SENSE reconstruction in the Cartesian case is efficiently performed by first creating one such aliased
ORIGINAL ARTICLE Digital Tomosynthesis Aided by Low-Resolution Exact Computed Tomography
"... Abstract: Tomosynthesis reconstructs 3-dimensional images of an object from a significantly fewer number of projections as compared with that required by computed tomography (CT). A major problem with tomosynthesis is image artifacts associated with the data incompleteness. In this article, we propo ..."

"... We have developed a tomosynthesis-based radioactive seed localiza-tion method for prostate brachytherapy. In contrast to the projection image-based matching approach, our method does not involve ex-plicit segmentation of seeds and can recover hidden seeds. Modified distance map images are computed f ..."

-cate that the implanted seed locations can be estimated from three or four images depending on the number of seeds if the pose of a C-arm is known. The algorithm was validated using phantom and clinical patient data. Index Terms — Tomosynthesis, prostate cancer, brachytherapy, modified distance map.
Ultra-Fast Digital Tomosynthesis Reconstruction Using General-Purpose GPU Programming for Image-Guided Radiation Therapy
"... www.tcrt.org The purpose of this work is to demonstrate an ultra-fast reconstruction technique for digital tomosynthesis (DTS) imaging based on the algorithm proposed by Feldkamp, Davis, and Kress (FDK) using standard general-purpose graphics processing unit (GPGPU) program-ming interface.

Assessment of time dependency in face recognition: an initial study
, 2003
"... Abstract. As face recognition research matures and products are deployed, the performance of such systems is being scrutinized by many constituencies. Performance factors of strong practical interest include the elapsed time between a subject’s enrollment and subsequent acquisition of an unidentifie ..."

In this paper, a long-term image acquisition project currently underway is described and data from the pilot study is examined. Experimental results suggest that (a) recognition performance is substantially poorer when unknown images
Materials for an exploratory theory of the network society.
- The British Journal of Sociology
, 2000
"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."
