10 How to extend New modality: Data model (storage and access structure) Import mapping and conversion Configuration definitions presentation: + data base + image selection + image annotation (monitor & film) + info/text page New clinical application: facility (User Interface) protocol print Philips Medical Systems 10 Common Digital Systems, Gerrit Muller

11 How to extend, other vendors New modality vendor (via DICOM): Customization data element semantics Validation New PACS vendor (via DICOM): Customization data element semantics Customization export: + matrix size + nr of bits + processing + graphics representation Validation Philips Medical Systems 11 Common Digital Systems, Gerrit Muller

12 Distributed applications USER DSI Client images Bolus chase request Print or export by ref. overview image(s) Easyvision R/F Server processed images to PACS film sheets Philips Medical Systems 12 Common Digital Systems, Gerrit Muller

13 Distributed applications USER Easyvision Rnn.m digitized audio MS word file electronic report Speech recognition RIS/HIS Philips Medical Systems 13 Common Digital Systems, Gerrit Muller

14 Distributed MR&CDS applications USER MR scanner based f.i. on IAP Client images PMSnet on DICOM Fancy function request Print or export by ref. overview image(s) Easyvision CT/MR Server processed images to PACS film sheets Philips Medical Systems 14 Common Digital Systems, Gerrit Muller

15 PMSnet, DICOM PMSnet, DICOM = network + protocol + data dictionary + services + model Services are: world wide standardized (store, query, etc.) multivendor PMS standardized (print, file, export) multi-modality Bi lateral agreed (CT: print via port number and fixed data elements) Unilateral supported (for instance: Muller! -> print) Philips Medical Systems 15 Common Digital Systems, Gerrit Muller

16 Services in PMSnet/DICOM Uni- and Bi-lateral services: simple fulfill many demands low implementation effort low functionality Standardized services: allow for full model: + Film low + Print Job Muller finished + Feedback on film output client side needs more code to benefit from full model. Philips Medical Systems 16 Common Digital Systems, Gerrit Muller

17 PMSnet on DICOM = DICOM + PMS services + detailed data dictionary + detailed model Philips Medical Systems 17 Common Digital Systems, Gerrit Muller

18 Status CDS: Transition from sequential development to parallel development Technology Improvement Plan: start phase 2 Interfacing, further manageability Software Process Improvement: + Strive for improved manageability, maintain innovation rate (requirement management, planning, etc.) + SW development environment (DDTS, Clearcase?) + Quantification (Metrics) (QAC?, project TU Delft) + Documentation Philips Medical Systems 18 Common Digital Systems, Gerrit Muller

19 Major phases Phase 1 (modularization): + Cleanup most obvious modules + First division in separate packages + Equalization of internal data model and PMS Data Dictionary + PMSnet, PMSdor, complete new + analysis (modularity, notifications, properties) Phase 2 (Interfacing): + Further modularity restructuring + Prototyping interface + Advanced development interface + Prepare external interface + Explore real time extensions(e.g. Threads) Philips Medical Systems 19 Common Digital Systems, Gerrit Muller

20 Major phases 2 Phase 3 (Internal benefit, standardization) + Explore C++ + Explore X + Implement 1D viewing + Use external interface Phase 4 (external benefit) + Decide on C++, X use + Use platform by non CDS clients Philips Medical Systems 20 Common Digital Systems, Gerrit Muller

21 Status june 1994 Modularity + CDS pack independent of rest SW + SW archive divided in groups, dependencies are analyzed and reduced Property management + file structure streamlined SPI support library + Implementation finished + Increased performance and functionality + Much less code + Configuration simpler PMSdor, PMSnet redesigned Solaris 2 HP: viewing ported, plan for product porting Philips Medical Systems 21 Common Digital Systems, Gerrit Muller

22 Cardio graphics: + additional functionality + cold graphics removed Data representation: + XDR based self describing object format Data base: + improved performance + support for spooled services Process structure: + import and export servers-> network server + spoolers and UNIX command server removed Memory usage: + ASW: 20% reduction (UNIX 20% increase) Documentation: + System level OK Philips Medical Systems 22 Common Digital Systems, Gerrit Muller
