Changes from Version 15 to Version 16

Version 16 of this C API has changed from version 15 as follows:

Feature Updates:

• LEADTOOLS medical imaging now supports all IODs and TAGS in 2008 base standard of DICOM 3.

  • LEADTOOLS version 16 now supports UNICODE and ANSI versions of the C API dlls. For information on the required dll name and import library, please refer to Files To Be Included With Your Application.

• LEADTOOLS DICOM version 16 adds support for reading and writing DICOM data sets with 1-bit image data.

• LEADTOOLS DICOM version 16 supports for creating/working with DICOM encapsulated documents.

• LEADTOOLS DICOM version 16 supports for multi-frame functional groups.

• LEADTOOLS DICOM version 16 enhanced DICOM communications.

• DICOM IOD tables and context mapping tables are now loaded on demand instead of at startup. Tables can optionally be not loaded at all, or loaded partially.

• When creating DICOMDIR with icon image or image preview for multi-frame DICOM, you can use representative Frame Number (0028, 6010) tag for the image frame.

• Additional high level interfaces were added to simplify the handling and creation of Enhanced MR and CT with Shared Functional Groups and Per-Frame Functional Groups.

• Also, additional high level interfaces were added to handle the following:

  • 1-bit Bitmap support

-   PDF encapsulated DICOM 
-   CDA encapsulated DICOM 
-   Raw Data encapsulation
