Very often we get questions about how to create DICOM files from externally imported images, such as BMP, JPG and Tiff, etc. Following are things which we have done for you during the file import and things you need to fill in to make the output a VALID DICOM file.
Call DicomImage.FileImport method to import external Images
Please note all group and element numbers below are in Hex format.
Attributes already set by DicomObjects during File Import:
(0008,0018) : SOP Instance UID (0020,000D) : Study Instance UID (0020,000E) : Series Instance UID (0028,0002) : Samples per Pixel (0028,0004) : Photometric Interpretation (0028,0006) : Planar Configuration (0028,0010) : Rows (0028,0011) : Columns (0028,0100) : Bits Allocated (0028,0101) : Bits Stored (0028,0102) : High Bit (0028,0103) : Pixel Representation (0028,1050) : Window Centre (0028,1051) : Window Width (7FE0,0010) : Pixel Data
Attributes you need to set before writing the Image out:
