Introduction<strong>VISUCAM</strong>1 Introduction1.1 PurposeThis DICOM Conformance Statement was written according to part PS 3.2 of [1].The intended audience for this Conformance Statement is hospital technical staff, system integratorsand software engineers. The reader is assumed to have good understanding of the DICOM standard.The Conformance Statement of one implementation can be compared with the ConformanceStatement of another implementation to determine which capabilities are commonly supported.DICOM does not, by itself, guarantee interoperability. Furthermore, the identification of commoncapabilities by comparing DICOM Conformance Statements is also not sufficient to guaranteeconnectivity between two devices.A DICOM Conformance Statement cannot replace validation and cross-vendor testing with otherdevices. Validation and cross-vendor testing are still required to ensure that both devices areperforming as intended.1.2 ScopeThe application described in this document is the <strong>VISUCAM</strong> Software from <strong>Carl</strong> <strong>Zeiss</strong> Jena GmbH,Germany. This software implements DICOM Offline Media Storage service and acts as File SetCreator.1.3 Definitions, Acronyms and AbbreviationsACR-NEMAAEDCOAmerican College of Radiology - National Electrical Manufacturers Association.Application EntityDICOM Composite Object.

<strong>VISUCAM</strong>Implementation Model2 Implementation ModelThe <strong>VISUCAM</strong> DICOM services are implemented as a single Application Entity which acts as ImageCreator and provides the DICOM Offline Media Storage service as File Set Creator. It provides aninterface to CD-R/RW , other mass storage devices and network connected file systems. The<strong>VISUCAM</strong> software includes a database for configuring and managing operating parameters.2.1 Application Data Flow DiagramLocal Real-WorldActivitiesCopyright © <strong>Carl</strong> <strong>Zeiss</strong> Meditec AG.

The Remote Real-World Activities are shown on the right and the Local Real-World Activities are shown on the left.2.2 Functional Definition of Application EntitiesThe <strong>VISUCAM</strong> Application Entity is designed to create DICOM images and write them to (shared)harddisk or an offline medium. It is capable of:• Creating a new File-set onto an unwritten medium (e.g. CD-RW)• Writing a new File-set to a network file system2.3 Sequencing of Real World ActivitiesA sequencing of Real-World Activities is not applicable.Seite 6 von 10<strong>Carl</strong> <strong>Zeiss</strong> Meditec AG

<strong>VISUCAM</strong>Extensions, Spezializations and Privatisations of SOP Classes4 Extensions, Spezializations andPrivatisations of SOP Classes4.1 Image Pixel Attribute Description for Grayscale ImagesThe <strong>VISUCAM</strong> application supports the MONOCHROME2 photometric interpretation pixelformat. The values are:• samples per pixel (attribute 0028, 0002) = 1• photometric interpretation (attribute 0028,0004) = “MONOCHROME2”• pixel representation (attribute 0028, 0103) = 0• bits allocated (attribute 0028, 0100) = 8• bits stored (attribute 0028,0101) = 8• high bit (attribute 0028,0102) = 7Copyright © <strong>Carl</strong> <strong>Zeiss</strong> Meditec AG. All rights reserved.Alle Rechte vorbehalten.4.2 Image Pixel Attribute Description for Color ImagesThe <strong>VISUCAM</strong> application supports the RGB color image description with the unsignedinteger 24 bit color image plane pixel format:• samples per pixel (attribute 0028, 0002) = 3• photometric interpretation (attribute 0028,0004) = “RGB”• pixel representation (attribute 0028, 0103) = 0• bits allocated (attribute 0028, 0100) = 8• bits stored (attribute 0028,0101) = 8• high bit (attribute 0028,0102) = 7• planar configuration (attribute 0028,0006) = 0.4.3 Acquisition Context ModuleThe <strong>VISUCAM</strong> application utilizes a special Coding Scheme to encode the AcquisitionContext Module:Coding Scheme "99HIKO" (see [3]):Coding Scheme Designator (0008,0102):Coding Scheme Version (0008,0103):99HIKOVP3.2Seite 8 von 10<strong>Carl</strong> <strong>Zeiss</strong> Meditec AG
