为防止在生成的时候会导致姓名等信息会出现乱码的，需要建一个初始化类。
这个最好是在程序启动的时候就初始化，因为放到生成图片里面才实例化，也会出现乱码的情况，使用方式如下

  MYIOManage.SetImplementation(MYIOManage.Instance);

    /// <summary>
    /// 点击(此处)折叠或打开MyIOManager.SetImplementation(MyIOManager.Instance);
    ///将fo-dicom使用的默认字符集修改一下。注意，我的类中BaseEncodingImpl取得的是Encoding.Default，意思就是取系统默认编码。这样在中文系统下就是GB2312或者GB18030了，就可以友好的支持中文了，而不 用在每次调用DicomDataSet的AddOrUpdate方法时指定编码了。是不是很方便呢。
