摘要： The invention discloses a method for calculating the signal-to-noise ratio (SNR) in parallel acquisition image reconstruction, comprising: determining a reconstruction expression for a linear operation of the image reconstruction; determining a weighted coefficient according to the reconstruction expression; calculating the SNR according to the weighted coefficient and the raw data. The SNR not only is relevant to the geometric shape and position of the coils, but also is influenced by the reconstruction method and the sampling mode. The SNR is calculated based on contribution of the raw data at positions in the reading direction from all the phase-coding lines in all acquisition channels. It reflects more precisely the loss of the SNR in the parallel acquisition image reconstruction, especially the changes in the SNR caused by the number of the reference lines combined during the reconstruction.

摘要： The invention discloses a method and an apparatus for reconstructing a parallel-acquired image, comprising: generating reconstruction data by combining uniformly under-sampled data and low-frequency fully-sampled data in MRI K-space according to a hybrid sampling mode; calculating the sensitivity distribution of a coil according to said low-frequency fully-sampled data; and reconstructing an image according to the reconstruction data, the coil's sensitivity distribution and the hybrid sampling mode. The signal to noise ratio of the reconstructed image is effectively improved by using the reconstruction data combined with the low-frequency fully-sampled data in reconstructing the image since the low-frequency fully-sampled data contains more useful information.

摘要： A biocompatible material may be configured into any number of implantable medical devices including intraluminal stents. Polymeric materials may be utilized to fabricate any of these devices, including stents. The stents may be balloon expandable or self-expanding. The polymeric materials may include additives such as drugs or other bioactive agents as well as radiopaque agents. By preferential mechanical deformation of the polymer, the polymer chains may be oriented to achieve certain desirable performance characteristics. The stent has a plurality of hoop components interconnected by a plurality of flexible connectors. The hoop components are formed as a continuous series of substantially longitudinally or axially oriented radial strut members and alternating substantially circumferentially oriented radial arc members. The geometry of the struts and arcs is such that when the stent is expanded, it has very high strains within a relatively small region. This strain localization results in what is often referred to as “hinging”, where the hinge is the small region within which the strains are very high.

摘要： The present invention is a method of shoot apical meristem transformation for monocot plant via sufficient and micro wounding (SMW). The technical process includes: expose the apical meristem by removing the coleoptile away when the shoot grows to 0.2-2 cm after 1-2 days of seed germination; make sufficient and micro wounding transformation to the apical meristem by stabbing and brushing for 2-3 times using the SMW brush having 100-5000 bristles which is 4-20 μm in diameter for each one and 0.5-3 mm in exposed length, and dipped with the Agrobacterium tumefaciens containing binary vector harboring exogenous genes; develop the treated meristems directly to normal plants after co-cultivation; promote the plants to develop big spikes and set more seeds; harvest the seeds of T0 plants separately; detect and identify the transformation results in T1 generation which is bred from each individual T0 plant. The advantages of the invention are independent of tissue culture, unlimited in genotype, unnecessary to carry resistant marker, simple and large scale to perform, and applicable to all monocot plants which can set seeds. The transformation efficiencies for wheat, rice and maize using this method are 49%, 66.3%, and 100%, respectively.
