E.1 Conformance Statement Overview​

This fictional product EXAMPLE-PRINT-SERVER-MANAGEMENT implements the necessary DICOM services to facilitate the Print​ (SCP)ImagingManagementinthehealthcaredepartments,managingPrintimagingoveranetworkonMedicalLaserImagingSystems.​ It enables the capabilities to capture images at any networked DICOM modality and then print them anywhere they're needed in the​ medical facility.​

Furthermore, before sending the images to be printed the EXAMPLE-PRINT-SERVER-MANAGEMENT will apply image processing,​ using presentation parameters and LUT to improve the image presentation quality and consistency. Moreover, it will manage the​ printing presentation format and the Printer queue and Configuration.​

Table E.1-1 provides an overview of the network services supported by EXAMPLE-PRINT-SERVER-MANAGEMENT.​

E.4.1 Implementation Model​

E.4.1.1 Application Data Flow​

This implementation model uses the DICOM Basic Print Management Meta SOP Class to receive studies for the Medical Imager.​ Multiple associations to Print SCUs are supported.​

Figure E.4.1-1. Application Data Flow Diagram​

The Print Server is receiving the Images with the Presentation and Annotation information, it Apply it on the images and creates a​ print-jobwithintheprintqueue,containingoneormorefilmpagescomposedfromimagesselectedbytheclientPrintSCU.Furthermore,​ it also manages the Printer Status and Configuration.​

E4.1.2 Functional Definition of AEs​

E.4.1.2.1 Functional Definition of Print Server (SCP) Application Entity​

ThePrintServerSystemacquirestheimageswiththedemographicsandpresentationinformationfromtheconnectedPrintComposer​ (SCU)thatisGroupedwithaWorkstationoranArchivedevice.Studiesaretemporarilystoredondisk.Theimagesarethenprocessed​ and formatted and finally queued as a print job on the Printer queue. If the Printer is operating normally, then the film sheets described​ in the print-job will be printed. Changes in the Printer operation status will be detected (e.g., film Magazine empty) and reported back​ to the Print SCU. If the Printer is not operating normally, then the print-job will be set to an error state and can be restarted by the​ user via the job control interface.​

The Print Server Management includes:​

•​DICOM Association and Negotiation Management​

•​Image Buffering​

•​Image Processing (Windowing level, P-LUT, GSDF, Annotation, etc)​

•​Image Formatting (Film sheet format)​

•​Printing​

•​Print Job Status Tracking​

•​Print Status Tracking​

•​Printer Configuration Tracking​

The Printer Status and Configuration can be requested at any time by the Print SCU, while the Print Server will update the Print SCU​ asynchronously whenever the Printer status get changed. Furthermore, the Print Server provides in addition a Service operation of​ checking the networking connectivity to it's Print SCU using the Verification SOP Class.​
