This paper proposes s new method to construct wavelets decomposing and reconstructing matrices of wavelet coefficients without iterative calculation in symmetrical extension for finite length signal ,and correspondingly gives the base vectors and basis images of 9/7 wavelet. The matrices can be used for image-partition processing based on wavelet method.
给出了对称延拓方式下有限长信号不需逐级计算而直接得到小波系数的分解矩阵和由这些小波系数重构原信号的重构矩阵的构造方法,并给出了常用的相应于9/7小波的分解矩阵和重构矩阵及其基向量,它们可广泛用于基于小波的图像分块处理中。

Results (1) Osteitis and destruction of end-plate showed long T1 and long T2.(2) Anterior and lateral abscess had long T1 and long T2 presenting even and structure-less signal.(3) The intervertebral discs showed normal or only degeneration at the early stage, and destroyed at later stage.(4) With Gd-DTPA enhancement, fibrotic granulation around abscess and destroyed area was well demonstrated.(5) Abscess in the bone and/or paraspinal abscess, destruction of end-plate were the important evidence for early diagnosis.
结果 (1)椎体骨炎及终板破坏呈长T1长T2信号,(2)椎旁或椎前冷脓肿呈长T1长T2均匀无结构信号,且上下跨越范围较大,(3)早期椎间盘信号正常或只出现退变,晚期则被破坏,(4)Gd-DTPA增强扫描可清楚显示冷脓肿周围纤维肉芽组织及椎管内侵犯,(5)骨内小脓肿和/或椎旁脓肿、椎体终板破坏是MRI诊断早期脊柱结核的重要依据。

The time-resolved technique currently used, is generally utilized to improve selectivity by adjusting delay sampling time. It is effective for eliminating the interference from signals with shorter lifetime to that with longer lifetime, but the revers is invalid.
目前所使用的时间分辨荧光光谱分析技术,一般都是通过延迟一定时间后再对样品信号采样,这对于消除短寿命信号对长寿命荧光信号的干扰非常有效,但不能消除长寿命信号对短寿命信号的干扰。

Results In 11 cases,5 cases were intracranial,and 6 cases intravertebral canal.MRI could effectively show similarly shuttle or long-round shape's abnormal signal imaging.The T1W imaging showed uniformity or asymmetric and low or equal signal.The borders were slighty low or equal signal intensity,some had spetum.The T2W imaging showed obviously high signal,and a few cases showed slightly high or equal signal,while the borders showed slightly low or equal signal imaging.The thin peripheral could be obviously enhanced,but without inner enhancement.
结果 11例中发生于颅内5例,椎管内6例,其 MRI 表现:断面上显示为在颅板下或椎管内的梭形或长圆形异常信号影, T1WI 上表现为均匀或不均匀的低、略低或等信号影,周边为略低或等信号的较厚边缘,少部分(2例)有分隔; T2WI 上多表现为较明显的高信号,少数呈等、略高信号,并可见略低或等信号的边缘;增强扫描病灶边缘明显强化,其内无明显强化或不强化,1例病灶呈较均匀的强化,1例病灶部分呈片状强化。

All metaphases showed three distinct green signals, which have the same size and intensity, corresponding to a normal chromosome 8 and two isochromosomes 8q, and five red signals, of which one was located on a normal chromosome 8 and the another two quite symmetrically on the both arms of each isochromosome 8q, respectively.
结果发现:所有中期分裂相均显示3个绿色荧光杂交信号和5个红色荧光杂交信号;2个绿色荧光杂交信号分别位于2条等臂8q染色体着丝粒处,信号大小和强度均与位于正常8号染色体着丝粒处的1个绿色荧光杂交信号相当;1个红色荧光杂交信号位于正常8号染色体长臂上,另外2个红色荧光杂交信号非常对称地位于每一条等臂8q染色体的两条长臂上。
