Sentence examples for maximum attenuation coefficients from inspiring English sources
The minimum and maximum attenuation coefficients obtained for each tissue type are presented in Fig. 3. Based on these ranges, thresholding was performed to generate a custom color map for segmenting tissue type and the resulting en face parametric image of attenuation is shown in Fig. 2(C).
In addition, the maximum attenuation coefficient in each attenuation zone is not affected by the initial stress.
The theoretical results show that the initial stress significantly alters the position and width of the attenuation zones, however, it does not affect the maximum attenuation coefficient.
Successive underwater scans at depth intervals between 5 and 50 cm down to a maximum depth of 3 m were done around noon and used to calculate the diffuse spectral attenuation coefficients, Ko (Smith, 1968).
Because the attenuation coefficient curve is not smooth in the frequency domain, the gradient-based optimization methods cannot be directly used in the design optimization of phononic band-gap materials to achieve the maximum attenuation within the desired frequency range.
The same effect was observed for mass attenuation coefficients comparison.
The overall transmittance, attenuation coefficients, coupling losses, bending losses, and damage-intensity thresholds were determined using four continuous-wave laser sources with the maximum output power of 300 mW and a pulsed 9 ns laser with the maximum output energy up to 1 mJ.
The correction for photon attenuation requires the availability of patient-specific attenuation map, which accounts for the spatial distribution of attenuation coefficients of biological tissues.
Three methods are used to provide partial attenuation compensation, using effective attenuation coefficients.
Profiles of attenuation coefficients and phase velocities.
