Abstract

The proposed Stream File Format (SFF) provides an application independent, Operating System agnostic, computer language neutral container file that can embed multiple streams of high bandwidth Ultrasound data with serializable objects for storing extensible meta-data.

1. Title of the Invention

An extensible method for archival & retrieval of high bandwidth ultrasound data

2. Abstract

The proposed Stream File Format (SFF) provides an application independent, Operating System agnostic, computer language neutral container file that can embed multiple streams of high bandwidth Ultrasound data with serializable objects for storing extensible meta-data.

3. Background Information

The Ultrasound machine is capable to generating high volumes of various kinds of data. The proposed method describes a technique for storing such data and provides a mechanism to extend the blueprint of basic structures.

This technique helps various applications to archive either on the same system or on the network with raw data and the corresponding meta-data in one logical entity. Such archived data can then be retrieved to reconstruct the original parameters along with the data. Since the whole concept is extensible, the base structures are reused, thus fuelling efficiency without sacrificing the compatibility.

DICOM standards are typically used to achieve storage and retrieval of such data. The custom tags are heavily used to embed meta information.

However, DICOM doesn't provide extensible structures and doesn't cater to the needs of sophisticated features that require object serialization as part of the ultrasound raw and meta-data.

By promoting the meta-data that are part of private-tags with select raw-data types and formats that were supported in the DICOM to first-class serializable objects, the proposed technique not only helps to bind various meta-data information with the Ultrasound raw data, but also handles data types and format that are not even considered in the DICOM standard.

4. Details

The SFF extends RIFF (Resource Interchange File Format) chunks for the layout. In order to provide a quick access to the SFF file, the headers are stored with "four character code" (FourCC) as tag Id. All the meta-data information is coded with specific FourCC as identifiers. In addition to adopting RIFF chunks, the SFF also extends AVI file format. Since AVI provides the necessary structures for non-standard streams and custom-headers, we use it effectively to add Ultrasound specific information as part of the file. This technique enables us to leverage AVI tools for parsing and analyzing the custom streams.

In order to meet the platform independence requirement, the binary layout of the file format must be specified. The attached diagram depicts the SFF binary specification.
