Ideal current patterns yielding optimal signal-to-noise ratio and specific absorption rate in magnetic reso- nance imaging: computational methods and physical insights. Magn. Reson. Med. 2012; 68(1): 286-304.Lattanzi, R. and D.K. Sodickson, Ideal current patterns yielding optimal signal-to-...
The signal-to-noise ratio (SNR) at the output of an ideal FM detector is determined as a function of the modulation index for the case of an SSB-FM signal plus narrow-band Gaussian noise at the input, where the input SNR is large. The modulation is assumed to be sinusoidal, and the...
募我院20例志愿者分别行冠状位STIR 及T2IDEAL 序列磁共振检查，对臂丛神经节后段两种扫描序列图像的图像伪影、信噪比(signal to noise ratio ,SNR )及对比噪声比（contrast to noise ratio ,CNR ）进行图像质量评价；（2）收集16例臂丛神经损伤患者行常规及T2IDEAL 检查，观察节后臂丛神经损伤的影像特征。结果：STIR...
The raw intensity optical image is converted to an electronic signal that can be digitally processed and then displayed on a monitor. In this system, the spatial intensity distribution emanating from the monitor is the final image. The task of the optical system to the left of the detector is...
aTHz的时域频谱信噪比很高,这使THz非常适用于成像应用。 The THz time domain frequency spectrum signal-to-noise ratio is very high, this causes THz to be suitable extremely for the image formation application.[translate]
Magnetic resonance imaging uses real and complex forms of the Fourier transform and to a lesser degree the Radon transform and their appropriate inverses. Under ideal conditions, these solutions are fast and optimal in the sense of signal-to-noise ratio (S/N). In practice, though, the phase ...
performance. For example, because the RF front end is the first section in the receiver chain, the design of its low noise amplifier is critical to achieving the desired signal to noise ratio (SNR). This example shows how to incorporate RF front end behavior into an existing radar system ...
The result showed clear signal/noise ratio and was highly reproducible. This solution also worked in vitro differentiated definitive endoderm cells (data not shown). Region 1 Region 2 Figure 1. ChIPmentation sequencing profiles for Gata6Chromatin preparation and immunoprecipitation have been performed ...
Therefore, an alternative approach is to fit the Z-spectra at low irradiation powers using a multi-pool Lorentzian model29, 32, 33. The reliability of these approaches depends strongly on the signal-to-noise ratio (SNR), which may be compromised by spatiotemporal resolution. Moreover, ...
