提供重建所需的属性，输入是rcvbuffer中的rfdata，输出是interbuff或者imagebuff。

  Recon =        senscutoff  [double]     0.0到1.0、灵敏度阈值，Cutoff value for excluding channel from sum.       pdatanum    [double]     定义重建数据像素位置PData结构索引，Number of PData structure to use.     rcvBufFrame [double]     帧编号为第一帧，-1为Rcvbuffer如果最后一个采集帧与上一个重建帧相同，等待1万ms（newFrameTimeout）传输新帧，如果没有，处理旧帧。If provided, overrides the frame no. in ReconInfo       newFrameTimeout [double] (dflt 1000 msec) Time (msecs) to wait for new frm       IntBufDest  [1x2 double] 指定接收重构目标缓冲区和帧，[InterBuffer number, frame number]       ImgBufDest  [1x2 double]  帧号设置为-1，表示下一帧用于输出[ImageBuffer number, frame number]       RINums      [n double]   对应ReconInfo号，Row vector of n ReconInfo structure nos. 

定义重建过程中每一步的细节

  ReconInfo =  mode       [string]    Numeric or string representation  txnum      [double]    发射索引号，获得发射波形特性，Number of transmit object used for acquisition.  rcvnum     [double]    其中，接收索引号endsample-startsample<4096，Number of receive object used for acquisition.  Aperture   [1xnumchannels double] 重建所使用的换能器通道，重建孔径与接收孔径一致时使用Apod阵列。(optional) aperture specification  regionnum  [double]    重建区域，参考PData.Region，定义所有区域结构。Number of Region structure for pixel data.  pagenum    [double]    每次采集一组彩色多普勒，10组计算需要采集Indicates page no. for multi-page InterBuffer  normPower  [double]    Optional normalization power (see text).  normWeight [double]    Optional normalization weight (see text).  scaleFactor [double]   Optional scale factor for all modes.  Pre        [string]    ’clearInterBuf’,‘clearImageBuf’,‘interleaveRF’  Post       [string]    ’IQ2IntensityImageBuf’,’…Add’,’…Mul’  threadSync [double]    default=0, 1=>sync after recon w this RI
