LEADTOOLS Recognition SDK – a Third-party Review

Recognition SDK

We were recently put in contact with an experienced technical blogger and web developer, Dick Strauss, about exploring the possibility of conducting a product review. He found our product line interesting and something his readers might benefit from. We were happy to partner up with him and gave him a development license for one of our most popular products, LEADTOOLS Recognition.

Not only did he navigate our documentation and rapidly implement both full-page and zonal OCR with little effort, but he found that LEADTOOLS was, in his opinion, a “stunning product” rather than just a “good functional product.” He experienced the entire process of using LEADTOOLS, including unlocking support with his development license, starting a project from scratch, and firing off some questions to our outstanding support department.

New White Paper: Integrating HL7 into Medical Applications with LEADTOOLS

This month, we have published a white paper on the new LEADTOOLS HL7 SDK technology that was added in Version 19. A versatile and popular messaging standard for medical applications, HL7 truly broadens the scope of LEADTOOLS SDKs. Since HL7 is a messaging standard for interoperability between any healthcare application, this new library within LEADTOOLS V19 can be used across the board in imaging (PACS) and non-imaging (EHR, RIS, HIS, billing, patient tracking, etc.) applications alike.

If you are developing any kind of application for the healthcare industry, this white paper is especially relevant as HL7 is already the worldwide messaging standard for the exchange of patient care and clinical information. We hope you enjoy this informative read about such an important standard, its general uses and how customers are using LEADTOOLS to implement it.

Integrating HL7 into Medical Applications with LEADTOOLS
Health Level Seven (HL7) Messaging has gained widespread popularity and acceptance as a flexible standard of exchanging structured electronic health information. HL7 can enable communication and interoperability between standardized information and imaging systems such as Electronic Health Records (EHR), Hospital Information System (HIS), Radiology Information System (RIS), Laboratory Information System (LIS) and Picture Archiving and Communication System (PACS), as well as any individual practice management or front-office application used by healthcare providers for tasks such as billing and patient tracking. The LEADTOOLS HL7 SDK simplifies the integration of complex HL7 standards into any healthcare application and developers can create full-featured, HL7-compliant PACS in record time.

In addition to the PDF download format, we have also published this white paper on The CodeProject.
