Hybrid dual-modality image processing systems and methods are disclosed. For example, an image processing system includes a computer for processing SPECT tomographic projection data and a CT volume image. The computer derives a SPECT transverse volume image from the projection data and registers the SPECT transverse volume image with the CT volume image to obtain an attenuation map and registration information. The computer uses the attenuation map and the registration information to derive a SPECT transverse volume image with attenuation correction. The computer uses the registration information to derive a SPECT transverse volume image without attenuation correction. The SPECT transverse volume images, with and without attenuation correction, are derived at or near the same time, using the same registration information. The registration information is stored in, carried by, or otherwise communicated through the attenuation map for subsequent processing of the SPECT transverse volume images.

Hybrid dual-modality image processing system and method

Methods, frameworks and systems for validating DICOM (Digital Imaging and Communications in Medicine) SR (Structured Reporting) XML (Extensible Markup Language) documents against DICOM SR templates, using XSLT (Extensible Stylesheet Language Transformations) technology alone or as a complement to XML Schema, are disclosed. A framework of generating XSLT stylesheets from XML representation of DICOM SR templates is developed. Also a mechanism and method of automatic generating XSLT stylesheets for validating SR document contents are provided. In addition, a mechanism and method of flexibly adapting in different DICOM SR XML formats is provided.

Framework of validating DICOM structured reporting documents using XSLT technology

A conversion system converts DICOM SR information from a DICOM-formatted file into an XML representation. By providing a mapping between DICOM SR and XML, the DICOM SR content material can be more easily processed by application programs that are DICOM-specific, such as medical analysis programs, as well as by application programs that are not DICOM-specific, such as routine clerical or data-management programs. In a preferred embodiment, a two-phase conversion is employed. The DICOM information is parsed and Fig converted directly into a 'raw' XML data set. Thereafter, the 'raw' XML is transformed into a proper XML output form, via an XSLT processor. Changes to the desired XML output form can thus be effected via changes in the corresponding XSLT stylesheets.

DICOM to XML generator

A method for mapping a DICOM document into a UML document is disclosed and claimed by this invention. The method includes mapping each DICOM Information Entity in the DICOM document into a corresponding UML class in the UML document, mapping each DICOM IOD Module in the DICOM document into a corresponding UML class in the UML document, mapping each DICOM Macro in the DICOM document into a corresponding UML class in the UML document, and mapping each DICOM Attribute in the DICOM document into a corresponding UML attribute in the UML document. It also includes a UML profile for DICOM information model which guides the UML modeling for all the DICOM IODs. It can also guide the genertion of XML schemas and DTDs from UML models based on this profile.

Precise UML modeling framework of the DICOM information model

A DICOM-to-XML conversion system is provided that converts the DICOM SR standard into a set of XML DTDs and Schemas. By providing a mapping between the DICOM SR standard and XML DTDs and Schemas, DICOM specific XML-based applications can be developed, via a larger field of XML-fluent application developers. Additionally, by providing standard XML DTDs and Schemas for containing DICOM data, other commonly available non-DICOM-related applications, such as accounting and mailing programs, can be structured to use information as required from DICOM reports that are converted to conform to these defined XML DTDs and Schemas. In a preferred embodiment, a two-phase conversion is employed. The DICOM SR specification is parsed and converted directly into a set of &ldquo;raw&rdquo; XML documents. Thereafter, the &ldquo;raw&rdquo; XML documents are transformed into the corresponding XML DTDs and Schemas, via an XSLT processor. Changes to the desired XML DTDs and Schemas, as standards develop, can thus be effected via changes in the corresponding XSLT stylesheets, without modification to the DICOM-to-raw-XML process.
