A fast intra mode decision algorithm for H.264/AVC is proposed in this paper. The objective is to reduce the encoder complexity without significant rate-distortion performance degradation. Three methods are adopted: (1) the block size is selected between 4times4 block and 16times16 block based on the smoothness and correlation information. (2) A(More)
The use of arsenic trioxide (As2O3, ATO) combined with all-trans retinoic acid (ATRA) has recently been reported to induce remission in patients with acute promyelocytic leukemia (APL). However, its efficiency remains inconclusive mainly due to the small number of the available cases. In this study, therefore, we present a clinical study using a combination(More)
For many image-guided interventions there exists a need to compute the registration between preprocedure image(s) and the physical space of the intervention. Real-time intraprocedure imaging such as ultrasound (US) can be used to image the region of interest directly and provide valuable anatomical information for computing this registration. Unfortunately,(More)
We present a technique for automatic intensity-based image-to-physical registration of a 3-D segmentation for image-guided interventions. The registration aligns the segmentation with tracked and calibrated 3-D ultrasound (US) images of the target region. The technique uses a probabilistic framework and explicitly incorporates a model of the US image(More)
Whole heart segmentation of 3D ultrasound (US), also referred to as echocardiography or simply echo, is useful in cardiac functional analysis to achieve quantitative diagnostic information of the heart. However, characteristics of US imaging such as limited field-of-view, artifacts and inconsistent intensity distribution makes automated approaches a(More)
The determination of twenty one kinds of constant and trace elements in Chinese herb Ranunculus ternatus thunb was performed by ICP-AES. The results show that K, Fe, Ca, Cr, Mg, Mn, Zn, Co, Cu, Ni, Se and Sr are relatively rich in Ranunculus ternatus and the content of Pb, Cd and As are very low. The ratio of the content of Zn to that of Cu is about 3,(More)
This paper presents a new registration framework for estimating myocardial motion and strain from multiple views of 3D ultrasound sequences. The originality of our approach resides in the estimation of the transformation directly from the multiple views rather than from a single view or a reconstructed compounded sequence. This allows us to exploit all(More)
This paper presents a novel method for compounding large numbers of multi-view 3D echocardiography volumes based on feature consistency. Our proposed method directly addresses issues involved with reducing the effects of echocardiography artefacts in the final compounded volume. Quantitative validation experiments are carried out using an echocardiography(More)
