The LEADTOOLS Medical Imaging product line includes everything programmers need to develop a complete DICOM Medical Imaging Solution. Create any DICOM Layer Actor in the IHE Framework; add support for any DICOM service; capture images from TWAIN, Screen, Video for Windows (VfW) driver, DV (Digital Video) driver and WDM driver sources; print via Windows printer driver or DICOM Print SCP; display 1-64 bit images including automatic zoom, pan and scroll functionally; process 1-64 bit image data; stream image or video data to a DICOM dataset; load, save and convert DICOM to any of over 100 image formats; as well as image annotation including functionality to create overlays; and convert DICOM datasets to AVI/MPEG files.
The LEADTOOLS DICOM .NET Class Library provides classes that enable you to incorporate DICOM support into your Windows applications. DICOM File Support and DICOM Security are available with all Medical Imaging products. DICOM Communication support is available only with the full Medical Imaging Suite.
With this toolkit, you can:
- Load, process, display, window level and save 12 and 16 bit grayscale images (including support for 16-bit grayscale TIFF).
- Detect and set LowBit and HighBit for image data, display images with automatic LUT intensity expansion, or set LUT entries and ranges with specific values and gradients.
- Display images through the LUT without changing the data, or process the image data using the LUT.

LEADTOOLS DICOM Security supports the Secure Transport Connection Profiles as specified in part 15 of the DICOM 2003 standard. Included in this add-on is support for TLS secure transport connection profile and ISCL Secure transport connection profile. The LEADTOOLS DICOM Security support eliminates the need of a VPN (virtual private network) for secure communication to comply with HIPAA regulations.
Use LEADTOOLS DICOM Security to encrypt sensitive data between DICOM nodes that you develop or existing nodes that support TLS or ISCL connection profiles.
HIPAA Privacy and Security required compliance by April 14, 2003 with standards for guarding data integrity, confidentiality and availability for any application that maintains or transmits individual health data. LEADTOOLS DICOM Security allows for quick, accurate, and complete implementation of security functions that will ensure an application connected to the Internet will be HIPAA compliant. Three areas of risk as well as computer/entity authentication, confidentiality and data integrity are addressed with the LEADTOOLS DICOM Security for efficient 128-bit encryption implementation.
