DICOM Format (DIC)

DICOM (DIC) files are commonly used in medical images. LEADTOOLS reads a broad range of DICOM formats, converting them to LEAD-supported bits-per-pixel as necessary.

Read Support is provided in all toolkits. Full support for this file format is available in Medical Imaging toolkits.

LEADTOOLS writes DICOM files in the LEAD-supported bits-per-pixel. DICOM files can contain many comment fields of various types. Use the L_ReadFileComment function to read comments in an existing file. Before writing a file, use the L_SetComment function to create an array of comments to be saved in the file. Use the L_DeleteComment function to delete a comment field from a file.

You can read DICOM files as follows:

You can write DICOM files as 8, 12, or 16-bit grayscale, 8-bit palettized color, or 24-bit RGB color (8 bits per plane).

 It is possible to speed up the loading of large DIC files. For more information, refer to Using Filter Data to Speed up Loading Large Files.
