A large number of observations will pr...

Malposition of venous cannula can cause inadequate venous drainage during cardiopulmonary bypass. It would be good clinical practice to use TEE to check the position of inferior venous cannula to avoid this problem at the earliest.

In truth, the authors have built the four scatter diagrams with regression line, but they have omitted to report the required regression equation for each of the drawn plots, i.e. within every plot the respective values of the intercept and beta-coefficient (slope) are lacking, in contrast with the good rule which provides for inclusion of the constant in equation, according to the scheme: Y( d...

Clutter affects almost any kind of visual technique and can obscure the structure present in the data even in small datasets, making it hard for users to find patterns and reveal relationships. In this paper we present a general strategy to analyze and reduce clutter using a special kind of sampling, together with an ad-hoc displacement technique and perceptual issues collected through a user s...

The purpose of this study was to evaluate different approaches for scatter artifact reduction in the field of dimensional computed tomography (CT). The methods we investigated can be subdivided into one software-based method and three hardware-based methods. The software-based method uses a Monte Carlo scatter simulation to estimate scatter intensities for an initial model of the geometrical an...
