UNLABELLED Cardiac SPECT images are degraded by photons scattered in the thorax. Accurate correction for scatter is complicated by the nonuniform density and varied sizes of thoraxes and by the additional attenuation and scatter caused by female patients' breasts. Monte Carlo simulation is a general and accurate method for detailed modeling of scatter. Hence, for 99mTc we compared statistical r...

The extraction of chemical information from dense particulate suspensions, such as industrial slurries and biological suspensions, using near-infrared (NIR) spectroscopic measurements, is complicated by sample-to-sample path-length variations due to light scattering. Empirical pre-processing techniques such as multiplicative scatter correction (MSC), extended MSC, and derivatives have been appl...

The Vis-NIR spectroscopy technology was studied on nondestructive measurement of sugar content in navel orange. Three different spectral ranges of 450-1000nm,1000-1800nm and 450-1800nm were selected, respectively and five different spectral pre-processing methods of Standard Normal Variate (SNV), first derivative (FD), second derivative (SD), multiplicative scatter correction (MSC) and smoothin...

Determination of the myristicin and alpha-pinene content nutmeg is still constrained by extended testing time in laboratory, which expensive carried out destructively. In addition, non-destructive using spectroscopy often faces problems building models that only rely on algorithms perform linearly, such as PCR PLSR. Therefore, present study studied Vis-NIR (381-1065 nm) a fast, inexpensive, mec...
