Interfile to DICOM using libraries.

[pma...@hggm.es]

Hi everyone;

Could someone say me How could I use the libraries for converting images in interfile format to DICOM?

Thanks in advance.

Here code solve jpeg to dicom:

public class Testjpg2Dcm {
    public static void main(String[] args) throws IOException, ImageReadException, ImageWriteException, Exception {
 
       
       
       
                     JFileChooser choix = new JFileChooser();
     choix.setFileSelectionMode(JFileChooser.FILES_ONLY);//sélectionne que le répertoire
                 
         
        int retour = choix.showOpenDialog(null);
     if(retour == JFileChooser.APPROVE_OPTION){
                   
        File fileInput = choix.getSelectedFile();
        JFileChooser saveDicom = new JFileChooser();
                saveDicom.setFileSelectionMode(JFileChooser.FILES_ONLY);
        saveDicom.setMultiSelectionEnabled(false);
        saveDicom.showSaveDialog(null);
        File fileOutput =saveDicom.getSelectedFile();
jpgdcm jpg = new jpgdcm(fileInput,fileOutput);

   
    }
}

Thank you Dimitri.

The format that I want to transform is similar to interfile but with more fields. Thinking about an interface for converting any image to DICOM. Because is faster and I needed for my job I will probably use the xml2dcm example ( any format (interface) -> XML -> DICOM ) instead directly to DICOM (any format (interface) -> DICOM). I will check your code and the xml2dcm code and I will do my best, lol. 

Best Regards.

I got something similar from the xml2dcm example, but what about a case with multiple slices and frames?

My idea is made sequence in VR=OW for Tag Pixel Data.
We will for example modality US.
I even can't  make. I think at this problem and make an example code.
 

[Pedro Macías Gordaliza]

Thank you Dimitri.

Afraid me neither, max I can do is split the raw data and create several DICOM files saving the position,thicness,ect in the corrects fields. 

Other issue for me is what can I do when I have 32-bit bits per sample?? (7FE0,0010) just allow OB or OW. maybe rescale slope?

[Dimitri Pianeta]

8, 16 bits or 32 bits per sample meant that (2^32)-2 (4GB), and (7FE0, 0010) (Pixel Data) can OW.

Computing Tag PixelData :

ROWS * COLUMNS * NUMBER_OF_FRAMES * SAMPLES_PER_PIXEL * (BITS_ALLOCATED/8) 

OW meant Other Word String.

[Pedro Macías Gordaliza]

Thank you Dimitri.

Thought OB goes for 1 - byte per sample and OW for 2 byte per sample, Which field can I use for indicating if the data is signed or unsigned? 

[Pedro Macías Gordaliza]

Forget the last one, too much working today.lol... silly question.

[Pedro Macías Gordaliza]

Last one,lol, What about float values? let's say 32 -bit real(float) values per pixel

These pixel Data can 32bits in integer (int).

[Pedro Macías Gordaliza]

...yeah I know, but as the same way is possible to indicate signed or unsigned with the pixel representation element, is there one for float ? I am trying with rescale but I am getting nothing.

[Dimitri Pianeta]

Let Pixel Representation (0028,0103) be  unsigned (0) or signed (1). By default, the tag (0028,0130) has value 0.
Pixel Representation has VR= US.
