Abstract. Displacement monitoring is a critical control for risks associated with potentially sudden slope failures. Instrument measurements are, however, obscured by the presence of scatter. Data filtering methods aim to reduce scatter and therefore enhance performance early warning systems (EWSs). The effectiveness EWSs depends on lag time between onset acceleration its detection system such ...

PURPOSE X-ray scatter is a significant impediment to image quality improvements in cone-beam CT (CBCT). The authors present and demonstrate a novel scatter correction algorithm using a scatter estimation method that simultaneously combines multiple Monte Carlo (MC) CBCT simulations through the use of a concurrently evaluated fitting function, referred to as concurrent MC fitting (CMCF). METHO...

The spatial recognition feature of near infrared hyperspectral imaging (HSI-NIR) makes it potentially suitable for Fusarium and deoxynivalenol (DON) management in single kernels to break with heterogeneity contamination wheat batches move towards individual kernel sorting provide more quick, environmental-friendly non-destructive analysis than wet-chemistry techniques. aim this study was standa...

Detection of gamma rays which Compton scatter within a patient but are still within the photopeak window of the Anger camera leads to inaccuracies in quantification of radioactivity from nuclear-medicine images. With the dual-energy-window correction method and a single (universal) scatter multiplier, the activity error is relatively large when there is tissue background with a large range of v...

Accurate scatter correction is one of the major problems facing quantitative 3D PET and many methods have been developed for the purpose of reducing the resultant degradation of image contrast and loss of quantitative accuracy. A new scatter correction method called Statistical Reconstruction-Based Scatter Correction (SRBSC) is proposed in this paper and evaluated using Monte Carlo simulations,...

OBJECTIVE The radioactivity count distribution in the brain must be determined accurately to accurately measure cerebral blood flow (CBF). Scatter and attenuation are factors that compromise the accuracy of determining radioactivity counts in the brain. METHODS We compared regional CBF in patients by an autoradiographic method using N-isopropyl-p-[123I] iodoamphetamine when, first, attenuatio...

Valine (C5H11NO2) is one of the most important amino acids in oilseed rape and has a close relationship with the influence of herbicide stress during growing stage. The traditional methods for amino acid detection were to use high performance liquid chromatography (HPLC) or amino acid analyzer. These methods were time consuming for preparation and detection, costly, laborious and not convenient...
