The contribution of contrast-enhanced color Doppler ultrasonography (CDUS) and dynamic flow (DF) (Toshiba) in the evaluation following treatment of hepatic tumors with radiofrequency (RF) is discussed.
W is amplitude contrast ratio, which denotes contribution of image contrast that result from inelastic scattering in the image formation that is dominated by elastic electron scattering, and γ(k) is phase shift produced by spherical aberration and defocus that can be described by the Scherzer formula (Williams and Carter 1996), γ k = π 2 C s λ 3 k 4 − 2 Δ zλ k 2 (3).
The contribution of dynamic contrast-enhanced ultrasound in antiangiogenic treatment assessment has been widely discussed by Lassau et al, 24, 32 underscoring the usefulness of this method as a functional modality for monitoring targeted treatments.
Here, we investigate the contribution of luminance and contrast information to global form detection, a stage between the extraction of local orientation and the recognition of objects.
LMMs with random coefficients were used to estimate the contribution of each visual contrast to the foraging efficiency of dichromats and trichromats respectively.
In particular the method for obtaining PS involves separating contribution of the delivery of contrast medium via the supply artery from the enhancement of the extracellular compartment of the tissue of interest by performing a deconvolution of the tissue TDC with respect to that of the supply artery.
The mixed contribution of elastic and inelastic contrast is discussed.
In the following, we highlight the main contribution of the paper: In contrast to our previous work [1], we use a more detailed and broadly suitable energy consumption model that explicitly considers both the energy consumed by each cell (sector) at a base station and models the basic energy consumed if at least one cell is active at a base station.
This confidence level allows us to quantify the contribution of the diffusion coherence contrast to the produced tracts.
Next, we analyze, with the help of the constructed confidence level, the contribution of the diffusion coherence contrast to every connection.
