"There is strong demand to make medical images more accessible for remote review, diagnosis, and collaboration between locations, and users are often constrained by limited network capacity or bandwidth", commented David Benini, Aware's director of product marketing. "AccuRad provides solution developers with software components that address these problems with DICOM-compatible JPEG 2000 and JPIP image compression, streaming, and viewing technology."
Aware's AccuRad is comprised of three software development kits (SDKs) that include libraries, sample applications with source code, a command line codec, and a Windows GUI tool with viewer. Aware's AccuRad J2KSuite enables JPEG 2000 compression and decompression. The AccuRad JPIPStream toolkit enables a developer to build JPIP-compliant servers and clients. Finally, AccuRad DICOMView ActiveX component combines the latest delivery and display technologies for viewing medical images in a standard browser and is easily integrated into other viewing applications.
Aware's AccuRad solution also includes implementations of the JPEG 2000 and JPIP imaging standards, which employ advanced compression and streaming techniques to greatly reduce the file size of medical images and improve transmission time. In addition to smaller file sizes, AccuRad's region of interest viewing and progressive display dramatically speeds up the image viewing process and is significantly more efficient for remote users, such as teleradiologists, accessing the images and volumes. All Aware products are fully supported and backed by the expertise developed by providing wavelet-based compression solutions since 1987.
JPEG 2000 is an image compression standard designed for a broad range of applications, including the compression and transmission of medical images. The standard is based on wavelet technology and a layered file format that offer lossless compression, diagnostic-quality lossy compression, and advanced system-level functionality. JPEG 2000 was created by the Joint Photographic Experts Group ("JPEG") and standardized by ITU-T SG16 and ISO/IEC JTC 1 SC 29 WG1. The standard is described by ITU-T T.800 and ISO/IEC 15444. Over 320 organizations from 21 countries contributed their expertise to the new standard which was formally approved in January, 2001.
JPIP is a client/server communication protocol defined in Part 9 of the JPEG 2000 (ISO/IEC 15444:9) suite of standards, officially entitled "Interactivity Tools, APIs and Protocols". JPIP enables a server to transmit only those portions of a JPEG 2000 image that are applicable to the client's needs. In conjunction with either HTTP or UDP protocols, JPIP enables the client to access metadata or other contents from the image file. This capability results in a vast improvement in bandwidth efficiency and speed when performing important and valuable image viewing tasks in a client/server environment, while reducing the storage and processing requirements of the client.
Digital Imaging and Communications in Medicine (DICOM) is an application layer network protocol for the transmission of medical images, waveforms, and ancillary information which supports a wide range of medical images across the fields of radiology, cardiology, pathology and dentistry. JPEG 2000 has been selected for inclusion in the DICOM standard for medical image transfer. DICOM Supplement 61 was ratified in November 2001 adding JPEG 2000 transfer Syntaxes to the protocol.
Aware is a veteran of the biometrics industry, providing biometric and imaging software components used in government systems worldwide since 1992. Aware's interoperable, standard-compliant, field-proven imaging products are used in a number of applications, from border management to criminal justice to medical imaging. Aware is also a technology supplier for the telecommunications industries. For more than ten years, Aware has pioneered innovations at telecommunications standards-setting organisations and continues to develop and market DSL silicon intellectual property and test and diagnostics products. Its StratiPHY IP product line supports DSL standards, including ADSL2+ and VDSL2, and has been broadly licensed to semiconductor companies. Telecom equipment vendors and phone companies use Aware's DSL test and diagnostics modules and Dr. DSL software to help provision DSL circuits globally.
