RIS中PDF转换DICOM文件(dicomcs )
RIS调用dicomcs 根据传入pdf路径 生成DCM文件的代码
说明:(非DCM图像,只是存储了)
生成DICOM文件的基本代码

info.PatientID = patid; //影像号
info.PatientName = CurPatient.PATNAME; //姓名
info.PatientSex = CurPatient.SEX; //性别

info.StudyID = modalityid; // 检查号
info.StudyInsUID = "2.2.280.7777." + modalityid;
info.StudyTime = CurApply.ACCESSION_DATE.ToString("hh:mm:ss"); //检查时间
info.FileName = Path.GetFileNameWithoutExtension(file); //文件名称
info.FileType = "pdf"; //类型
info.Modality = "SR"; //l类型
string outFile = string.Format(@"{0}\{1}_{2}.dcm", tempDicomPath, modalityid, info.FileName); //输出路径
deal.GenerateFileDicom(info, outFile); //生成文件FileDicom 类,生成文件:
