  • generative model transformer an Open Source mda tool Initiative
    Conference on Object-Oriented Programming Systems Languages and Applications, 2003
    Co-Authors: Jorn Bettin, Ghica Van Emde Boas, E.d. Willink
    Abstract:

    The Generative Model Transformer (GMT) project is an Open Source Initiative to build a Model Driven ArchitecureTM tool that allows fully customisable Platform Independent Models, Platform Description Models, Texture Mappings, and Refinement Transformations. The project should result in (a) a tool that fulfils the MDA promise for faster/more accurate/better maintainable application development, (b) a tool for industrial use, and (c) MDA related research-which is encouraged and needed. A distinctive feature of GMT is the emphasis of model transformations as "first-class model citizens". The implementation of model transformations is envisaged to be in conformance with the future OMG modeling standard for Queries, Views, and Transformations (QVT).

  • su f brb 16 a spreadsheet based automatic trajectory generator sage an Open Source tool for automatic creation of truebeam developer mode robotic trajectories
    Medical Physics, 2015
    Co-Authors: A Etmektzoglou, P Mishra, M Svatos
    Abstract:

    Purpose: To automate creation and delivery of robotic linac trajectories with TrueBeam Developer Mode, an Open Source spreadsheet-based trajectory generation tool has been developed, tested and made freely available. The computing power inherent in a spreadsheet environment plus additional functions programmed into the tool insulate users from the underlying schema tedium and allow easy calculation, parameterization, graphical visualization, validation and finally automatic generation of Developer Mode XML scripts which are directly loadable on a TrueBeam linac. Methods: The robotic control system platform that allows total coordination of potentially all linac moving axes with beam (continuous, step-and-shoot, or combination thereof) becomes available in TrueBeam Developer Mode. Many complex trajectories are either geometric or can be described in analytical form, making the computational power, graphing and programmability available in a spreadsheet environment an easy and ideal vehicle for automatic trajectory generation. The spreadsheet environment allows also for parameterization of trajectories thus enabling the creation of entire families of trajectories using only a few variables. Standard spreadsheet functionality has been extended for powerful movie-like dynamic graphic visualization of the gantry, table, MLC, room, lasers, 3D observer placement and beam centerline all as a function of MU or time, for analysis of the motions before requiring actual linac time. Results: We used the tool to generate and deliver extended SAD “virtual isocenter” trajectories of various shapes such as parameterized circles and ellipses. We also demonstrated use of the tool in generating linac couch motions that simulate respiratory motion using analytical parameterized functions. Conclusion: The SAGE tool is a valuable reSource to experiment with families of complex geometric trajectories for a TrueBeam Linac. It makes Developer Mode more accessible as a vehicle to quickly translate research ideas into machine readable scripts without programming knowledge. As an Open Source Initiative, it also enables researcher collaboration on future developments. I am a full time employee at Varian Medical Systems, Palo Alto, California

  • th c 12a 12 veritas an Open Source tool to facilitate user interaction with truebeam developer mode
    Medical Physics, 2014
    Co-Authors: P Mishra, J Lewis, T Etmektzoglou, M Svatos
    Abstract:

    Purpose: To address the challenges of creating delivery trajectories and imaging sequences with TrueBeam Developer Mode, a new Open-Source graphical XML builder, Veritas, has been developed, tested and made freely available. Veritas eliminates most of the need to understand the underlying schema and write XML scripts, by providing a graphical menu for each control point specifying the state of 30 mechanical/dose axes. All capabilities of Developer Mode are accessible in Veritas. Methods: Veritas was designed using QT Designer, a ‘what-you-is-what-you-get’ (WYSIWIG) tool for building graphical user interfaces (GUI). Different components of the GUI are integrated using QT's signals and slots mechanism. Functionalities are added using PySide, an Open Source, cross platform Python binding for the QT framework. The XML code generated is immediately visible, making it an interactive learning tool. A user starts from an anonymized DICOM file or XML example and introduces delivery modifications, or begins their experiment from scratch, then uses the GUI to modify control points as desired. The software automatically generates XML plans following the appropriate schema. Results: Veritas was tested by generating and delivering two XML plans at Brigham and Women's Hospital. The first example was created to irradiate the letter ‘B’ with a narrow MV beam using dynamic couch movements. The second was created to acquire 4D CBCT projections for four minutes. The delivery of the letter ‘B’ was observed using a 2D array of ionization chambers. Both deliveries were generated quickly in Veritas by non-expert Developer Mode users. Conclusion: We introduced a new Open Source tool Veritas for generating XML plans (delivery trajectories and imaging sequences). Veritas makes Developer Mode more accessible by reducing the learning curve for quick translation of research ideas into XML plans. Veritas is an Open Source Initiative, creating the possibility for future developments and collaboration with other researchers. I am an employee of Varian Medical Systems.
