In this paper, we propose a slice-based interactive segmentation of spectral CT datasets using a bag of features method. The data is acquired from a MARS scanner which divides up the x-ray spectrum into multiple energy bins for imaging. [...]

Assessment of metal implant induced artefacts using photon counting spectral CT
/ Amma, Maya Rajeswari (Otago U.) ; Butler, Anthony P H (MARS Bioimaging ; Canterbury U. ; Otago U.) ; Raja, Aamir Y (Otago U.) ; Bamford, Benjamin (Otago U.) ; Butler, Philip (MARS Bioimaging ; Canterbury U. ; Otago U.) ; Walker, E Peter (Otago U.) ; Matanaghi, Aysouda (Otago U.) ; Adebileje, Sikiru A (Otago U. ; Canterbury U.) ; Anderson, Nigel (Otago U.) ; Anjomrouz, Marzieh (MARS Bioimaging) et al.
The aim is to perform qualitative and quantitative assessment of metal induced artefacts of small titanium biomaterials using photon counting spectral CT. The energy binning feature of some photon counting detectors enables the measured spectrum to be segmented into low, mid and high energy bins in a single exposure. [...]

MARS pre-clinical imaging: the benefits of small pixels and good energy data
/ Butler, Philip H (MARS Bioimaging ; Canterbury U. ; Otago U.) ; Adebileje, Sikiru A (Otago U. ; Canterbury U.) ; Alexander, Steven D (MARS Bioimaging) ; Amma, Maya R (Otago U.) ; Amjomrouz, Marzieh (MARS Bioimaging) ; Asghariomabad, Fatemeh (Otago U.) ; Atharifard, Ali (MARS Bioimaging) ; Atlas, James (Canterbury U.) ; Bamford, Benjamin (Otago U.) ; Bell, Stephen T (MARS Bioimaging) et al.
Images from MARS spectral CT scanners show that there is much diagnostic value from using small pixels and good energy data. MARS scanners use energy-resolving photon-counting CZT Medipix3RX detectors that measure the energy of photons on a five-point scale and with a spatial resolution of 110 microns. [...]

Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider
/ Alimena, Juliette (Ohio State U.) ; Beacham, James (Duke U.) ; Borsato, Martino (Heidelberg U.) ; Cheng, Yangyang (Cornell U., LNS) ; Cid Vidal, Xabier (Santiago de Compostela U.) ; Cottin, Giovanna (Adolfo Ibanez U. ; Chile U., Catolica ; Taiwan, Natl. Taiwan U.) ; De Roeck, Albert (CERN) ; Desai, Nishita (Tata Inst.) ; Curtin, David (Toronto U.) ; Evans, Jared A. (Cincinnati U.) et al.
Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Hadron Collider (LHC) at CERN, these long-lived particles (LLPs) can decay far from the interaction vertex of the primary proton-proton collision. [...]
