Magnetic Resonance Imaging allows for minimally invasive targeting and thermal ablation of tumors while monitoring the temperature distribution. Conventional MR thermometry procedures are hampered by either low accuracy or high sensitivity to motion artifacts due to the use of a reference temperature image. A new, dual-echo technique has been developed to obtain the temperature distribution wit...

Fluoroscopic overlay images rendered from pre-operative volumetric data can provide additional guidance for physicians during catheter ablation procedures for treatment of atrial fibrillation (AFib). As these overlay images are compromised by cardiac and respiratory motion, motion compensation methods have been proposed. The approaches so far either require simultaneous biplane imaging for 3-D ...

Abstract. A heave compensation system is one of the absolutely necessary instruments to secure mining operation. The heave compensation system includes a heave compensated platform which is to compensate heave motion and a gimbaled platform which is to accommodate pitch and roll. The simulation of a nonlinear model based on fuzzy PID control is performed. The results show that the compensation ...

We identify and test a specific psychological mechanism underlying cross-national differences in preferences for performance-based versus redistributive compensation systems. We posit that individuals’ beliefs in the inherent justness and deservedness of individual outcomes (i.e., just world beliefs: JWBs) can help explain individual and culture-level variation in preferences for these compensa...

Judging object trajectory during self-motion is a fundamental ability for mobile organisms interacting with their environment. This fundamental ability requires the nervous system to compensate for the visual consequences of self-motion in order to make accurate judgments, but the mechanisms of this compensation are poorly understood. We comprehensively examined both the accuracy and precision ...

Is it time for a vaccine injury compensation scheme in Australia? The answer in part requires an assessment of how well the current ‘modified common law’ system serves to compensate those who suffer vaccine injuries. By considering the basic approach of the current common law1 and looking at cases previously decided, it should become possible to reach an informed conclusion on the relative meri...

This paper deals with the coding of the partition information resulting from the segmentation of video se quences Motion compensation of partition sequences is described as an e cient inter frame mode of coding It involves the prediction of the partition the computation of the partition compensation error the simpli cation of the error and its transmission The major issues and processing steps ...
