Getting more for less: adaptive X-ray fluorescence sampling for imaging

More for Less - Getting More Clients by Broadcasting Less Data

Broadcasting is scalable in terms of served users but not in terms of served data volume. Additionally, waiting time deadlines may be difficult to uphold due to the data clutter, forcing the clients to flee the system. This work proposes a way of selecting subsets of the original data that ensure near-optimal service ratio. The proposed technique relies on the novel data compatibility distance,...

Adaptive sampling for rover x-ray lithochemistry

Planetary rovers arriving at a new site may only have time to deploy contact instruments at a few selected locations before the mission must progress to the next locale. Since the number of command cycles is limited, operators typically script entire measurement sequences in advance. Onboard data analysis can improve the quality of these measurements by reacting immediately to collected data an...

Synthesis and characterization of Gd2O2 S: Tb3+ phosphor powder for X-ray imaging detectors

Gadolinium oxysulfide phosphor doped with trivalent terbium have been synthesized using urea homogenous precipitation and followed by sulfurization at 800 °C under argon atmosphere. Structural and morphological of synthesized phosphor powder were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectrometry (FT-IR). Hexagonal structure ...

An x-ray fluorescence imaging system for gold nanoparticle detection.

Gold nanoparticles (GNPs) may be used as a contrast agent to identify tumour location and can be modified to target and image specific tumour biological parameters. There are currently no imaging systems in the literature that have sufficient sensitivity to GNP concentration and distribution measurement at sufficient tissue depth for use in in vivo and in vitro studies. We have demonstrated tha...
