How to replace Image in Dicom file

[buiductoan]

Hello everybody, I have a DICOM file include header and image. I want to replace the image in dicom file by other image (example testimage.jpg). So I will use DicomImage class to do it. But I don't know function to do it. How to replace Image in Dicom file?
My idea has two steps:
+ First step, I will delete image in the Dicom file
+ Second stem, I will add a new Image in DICOM file.
Is my idea correct or not correct?

Instead of trying to replace the PixelData, you can create a new image, copy the original header, add the new pixeldata and save with the same filename as the original.

I think this idea not accurate. Because you can not copy all information in header and dataset in a new file. Instead of you must get pixel data from jpg file and copy it into PixelData Tag in DICOM file. But I try to copy but not successfully. The first I will convert image to dataset by code

Code: Select all

Image2Dcm i2d;
I2DOutputPlug *outPlug = new I2DOutputPlugSC();
I2DImgSource *inputPlug = new I2DJpegSource();
E_TransferSyntax writeXfer;
inputPlug->setImageFile("abc.jpg");
DcmDataset *dataset = NULL;
OFCondition result = i2d.convert(inputPlug, outPlug, dataset, writeXfer);

The second I will get pixelData in dataset and using putAndInsertUint8Array in the dicomfile refference from http://support.dcmtk.org/wiki/dcmtk/how ... essed-data, after I can not open the dicom.
