How do I change Transfer Syntax for DICOM images using sample Java sources?

Question

Hi,
I tested using Note:876534.1 Java API samples. It works fine when I put the "Implicit VR Little Endian" DICOM file.
I could insert the DICOM file, also I could get the all DICOM tags correctly by SQL.
But I could not get all DICOM tags when inserted "Explicit VR Little Endian" and "JPEG Lossy" DICOM file.
Also I could not find how to change the Transfer Syntax to orddicom Java API.
How do I change following simple java source for inserting different Transfer Syntax DICOM file?
Connection conn = DriverManager.getConnection(args[0], args[1], args[2]);
System.out.println("Got database connection");
conn.setAutoCommit(false);
Statement stmt = conn.createStatement();
CallableStatement cs = null;
cs = conn.prepareCall("begin ord_dicom.setDataModel(); end; ");
cs.execute();
cs.close();
String rowInsertSQL = "insert into dicom_test (id, dcmobj) values (" + args[3] + ",ordsys.orddicom())";
stmt.execute(rowInsertSQL);
System.out.println("Inserted empty dicom object ...");
String rowSelectSQL = "select dcmobj from dicom_test where id = " + args[3] + " for update";
OracleResultSet rset = (OracleResultSet)stmt.executeQuery(rowSelectSQL);
rset.next();
OrdDicom dcmProxy = (OrdDicom)rset.getORAData("dcmobj", OrdDicom.getORADataFactory());
rset.close();
System.out.println("selected row for update...");
File testFile = new File(args[4]);
boolean success = dcmProxy.loadContent(testFile, true);
dcmProxy.setProperties();
if (success) {            
String updateSQL = "update dicom_test set dcmobj=? where id=" + args[3];
OraclePreparedStatement opstmt =
(OraclePreparedStatement)conn.prepareStatement(updateSQL);
opstmt.setORAData(1, dcmProxy);
opstmt.execute();
int contentLength = dcmProxy.getContentLength();
String SOPInstanceUID = dcmProxy.getSOPInstanceUid();
System.out.println("contentLength: " + contentLength);
System.out.println("SOPInstanceUID: " + SOPInstanceUID);
opstmt.close();
Thanks,
Tatsuya

Answer 1

It would go like this
1. TIFF + XML metadata => DICOM image file
you can use the method ord_dicom.createDicomImage(src blob, metadata xmltype, dest blob) to create the DICOM image in a blob.
2, then use the ORDDicom constructor ORDDIcom(data blob) to create an ORDDicom object
3. then use the ORDDicom processCopy method to change the image properties.
Alternatively you can change image properties on the input TIFF image (using ORDImage methods) then create the DICOM image. If you are happy with the image properties then you can skip step 3.
