Particle detection and classification using commercial off the shelf CMOS image sensors
(Elsevier Science, 2016-04)
In this paper we analyse the response of two different Commercial Off The shelf CMOS image sensors as particle detectors. Sensors were irradiated using X-ray photons, gamma photons, beta particles and alpha particles from ...
Interpretation of x-ray images to investigate the viability of incorporating poly (Ethylene-co-vinyl acetate) (eva) waste in portland cement
(2019-01-01)
EVA (poly(ethylene-co-vinyl acetate)) is a copolymer widely used in the Brazilian footwear industry, where approximately 18% of the EVA remains as waste, principally after the cutting out of insoles. EVA wastes cannot be ...
An automatic correction method for the heel effect in digitized mammography images
(SPRINGER, 2008)
The most significant radiation field nonuniformity is the well-known Heel effect. This nonuniform beam effect has a negative influence on the results of computer-aided diagnosis of mammograms, which is frequently used for ...
Automated fish bone detection using X-ray imaging
(ELSEVIER SCI LTD, 2011)
In countries where fish is often consumed, fish bones are some of the most frequently ingested foreign bodies encountered in foods. In the production of fish fillets, fish bone detection is performed by human inspection ...
Caracterización morfológica por micro-tomografía computada de piezas dentales con tratamientos de conducto
(2022-07)
La micro-tomografía (CT) es una de las técnicas analíticas de contraste por absorción por medio de imágenes de rayos X de interés en diversas áreas de ciencia y tecnología, por su capacidad de lograr una caracterización ...
X-ray micrographic imaging system based on COTS CMOS sensors
(John Wiley & Sons Ltd, 2018-06-04)
This paper presents the use of commercial off the shelf CMOS image sensors for the acquisition of X-ray images with high spatial resolution. The X-ray images, with application in biology, electronic components inspection, ...
H alpha Imaging of X-ray Sources in Selected Globular Clusters with the SOAR Telescope
(2009)
We present results of a search for objects with H-alpha excess, such as cataclysmic variables (CVs) and chromospherically active binaries (ABs), as counterparts to X-ray sources detected with Chandra satellite observatory ...
Active X-ray testing of complex objects
(BRITISH INST NON-DESTRUCTIVE TESTING, 2012)
X-ray testing of complex objects - such as luggage screening at airports - is usually performed manually. This is not always effective, since it depends strongly on the pose of the objects of interest (target objects) and ...
Simulation of defects in aluminium castings using CAD models of flaws and real X-ray images
(BRITISH INST NON-DESTRUCTIVE TESTING, 2005)
In order to evaluate the sensitivity of defect inspection systems, it is convenient to examine simulated data. This gives the possibility to tune the parameters of the inspection method and to test the performance of the ...
Evaluation of a Commercial Off The Shelf CMOS Image Sensor for X-ray spectroscopy up to 24.9 keV
(Pergamon-Elsevier Science Ltd, 2020-12)
We studied the X-ray spectroscopy capability and the detection efficiency of a low cost Commercial Off The Shelf CMOS Image Sensor (CIS) in the energy range from 6.4 to 24.9 keV using the fluorescence spectra emitted by ...
