Interactive image segmentation of MARS datasets using bag of features / Kanithi, Praveenkumar (Canterbury U.) ; de Ruiter, Niels J A (Canterbury U. ; Otago U. ; MARS Bioimaging) ; Amma, Maya R (Otago U.) ; Lindeman, Robert W (Canterbury U.) ; Butler, Anthony P H (Canterbury U. ; MARS ; Otago U. ; CERN) ; Butler, Philip H (Canterbury U. ; MARS Bioimaging ; Otago U. ; CERN) ; Chernoglazov, Alexander I (Canterbury U. ; MARS Bioimaging) ; Mandalika, V B H (Canterbury U. ; MARS Bioimaging) ; Adebileje, Sikiru A (Canterbury U. ; Otago U.) ; Alexander, Steven D (MARS Bioimaging) et al.
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. [...]

Medipix3RX neutron camera for ambient radiation measurements in the CMS cavern / Bheesette, Srinidhi (Otago U. ; CERN) ; Lokhovitskiy, Arkady (CERN) ; Mallows, Sophie (CERN) ; Walsh, Michael F (MARS Bioimaging) ; Doesburg, Robert M N (MARS Bioimaging) ; Bell, Stephen T (MARS Bioimaging) ; Dabrowski, Anne (CERN) ; Butler, Anthony P H (Otago U. ; CERN ; MARS Bioimaging ; Canterbury U.) ; Butler, Philip H (Otago U. ; CERN ; MARS Bioimaging ; Canterbury U.) ; Adebileje, Sikiru A (Otago U.) et al.
We describe a CMS-Medipix3RX neutron camera developed by adapting and modifying detector readout electronics developed at the University of Canterbury. The readout electronics are part of the MARS x-ray scanner used for imaging applications [1]. [...]

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. [...]

Semi-analytic off-axis X-ray source model / Shamshad, M (U. Otago, Dept. Radiol.) ; Anjomrouz, M (U. Otago, Dept. Radiol.) ; Smithies, D J (MARS Bioimaging) ; Largeau, A (Telecom Phys., Strasbourg) ; Lu, G (Canterbury U.) ; Atharifard, A (U. Otago, Dept. Radiol.) ; Vanden Broeke, L (Canterbury U.) ; Aamir, R (U. Otago, Dept. Radiol. ; MARS Bioimaging) ; Panta, R K (U. Otago, Dept. Radiol. ; MARS Bioimaging) ; Walsh, M F (MARS Bioimaging) et al.
Spectral computed tomography (CT) systems are employed with energy-resolving photon counting detectors. Incorporation of a spectrally accurate x-ray beam model in image reconstruction helps to improve material identification and quantification by these systems. [...]

Per-pixel energy calibration of photon counting detectors / Atharifard, A (Otago U.) ; Healy, J L (Canterbury U.) ; Goulter, B P (MARS Center) ; Ramyar, M (Otago U.) ; Broeke, L Vanden (Canterbury U.) ; Walsh, M F ; Onyema, C C (Canterbury U.) ; Panta, R K (Otago U.) ; Aamir, R (Otago U.) ; Smithies, D J et al.
Energy resolving performance of spectral CT systems is influenced by the accuracy of the detector's energy calibration. Global energy calibration maps a given threshold to the average energy response of all pixels of the detector. [...]

Oblique fluorescence in a MARS scanner with a CdTe-Medipix3RX / Broeke, L Vanden (Canterbury U.) ; Atharifard, A. (Unlisted, NZ) ; Goulter, B.P. (Unlisted, NZ) ; Healy, J.L.

(Telecom Phys., Strasbourg) ; Mueller, K. (Lubeck, Fachhochschule) et al.
The latest version of the MARS small bore scanner makes use of the Medipix3RX ASIC, bonded to a CdTe or CZT semi-conductor layer, to count x-ray photons and create a spectroscopic CT data set. The MARS imaging chain uses the energy-resolved 2D transmission images to construct quantitative 3D spectral and material images. [...]
