Event pictures

This is a working meeting - the goal is to start writing code! The event will look something like these pictures from the May 2010 meeting in Washington.

Introduction

Date: September 13-17 2010

Location: Barcelona

Agenda: Nominally 9am to 5pm each day Monday through Friday. Monday will start with a review of the topics. Anyone who has prepared material they would like to present can suggest a time slot so a detailed agenda for the rest of the week can be prepared. Unless otherwise allocated, it is expected that the time will be spent hacking, with ad hoc discussions and debugging sessions as needed.

  • Monday
    • 9am - welcome
    • Everyone should say a few words of what they want to accomplish during the week. Also state if you would like to present on a topic and lead a discussion so these can be added to the agenda.
    • Review of git methodologies (Jc, Benoit, Sascha and all)
  • Tuesday
  • Wednesday
    • afternoon status update from everyone, review to-do items for the rest of the week.
  • Thursday
  • Friday
    • afternoon summary of progress and discussion of ongoing work, future {talk,hack}fests...

Goal: A follow on to the wildly successful March 2010 pre-hackfest and May 2010 hackfest .

Requirements: attendees must be enthusiastic about CTK and willing to spend their time with the details of dicom, git, cmake, c++, Qt, vtk, itk, openinventor, and related technologies. People who do not feel qualified for this are politely not invited :)

Group size: maximum 20 participants so we can have a manageable working meeting. The organizing committee will invite and select participants based on input from TheTeam.

Organizers: Ivo Wolf, Steve Pieper, Stephen Aylward

Site Hosts: TBD

Attendees: (due to limited space, please contact the organizers to attend)

  1. Steve Pieper, Isomics, Inc., USA
  2. Ivo Wolf, Hochschule Mannheim and DKFZ, Germany
  3. Marco Nolden, DKFZ, Germany
  4. Sascha Zelzer, DKFZ, Germany
  5. Julien Finet, Kitware, USA
  6. Jean-Christophe Fillion-Robin Kitware, USA
  7. Xavi Planes, Spain
  8. Daniele Giunchi, Italy
  9. Alessandro Chiarini, Italy
  10. Paolo Quadrani, Italy

Future Events: The organizing committee invited a group of developers to get the CTK project started and we've believe we've reached capacity for this event. Future hackfests will be announced in advance and we hope lots of people will be interested in participating. The venue and activities at future hackfests will be determined based on the number of active participants in the project.

Preparation

Developers should bring a laptop with the current CTK source code downloaded and built.

Use the CTK developers mailing list to discuss build issues and topics for ongoing work.

We plan to hold weekly phone conferences during the month leading up to the actual hackfest. Be prepared to discuss projects so we can make the most effective use of the face-to-face hackfest time.

Preliminary Agenda

  • Monday, 9am - 5pm:
    • git workflow
    • other presentations (please add here)
    • DICOM Application Hosting in CTK (Sascha)
    • ...
  • Thursday to Friday, 9am - 5pm:
    • coding in small groups

Topics and Projects

Pick up threads of discussion and activity from Pre-Hackfest and May 2010 Hackfest

General set of topics (attendees, please flesh this out with your own ideas!)

Schedule Talkfest

  • Pick a time and place for a talkfest in the US (perhaps at Washington University in St. Louis).

Review driving application

  • First: Define the purpose of CTK:
    • Candidate: CTK is meant to span the boundaries of current toolkits and applications. Specifically, its parts are intended to be easily integrated into current software systems and help them address software engineering challenges that impede their clinical use. We are currently focusing simplifying the challenging tasks of (1) integrating DICOM Q&R functionality into applications (i.e., thereby enabling the integration of applications into the data workflow of a clinical environment) and (2) providing clean and effective user interfaces that are appropriate for use in a clinical environment (e.g., intuitive user-interface widgets for window and level selection). Future challenges to be addressed include methods for software testing, event handling, and more.
  • Second: Define the driving application to be bundled with CTK (that demonstrates the utility of CTK).
    • "cool" application for users = "WOW!" application for computer scientist
    • Candidate: The WOW! application could be achieved by working towards three goals:
      • Goal1: Provide Qt widgets for browsing data on a PACS and downloading (Q&R) select images to local disk.
        • Should support batch download based on selected slices, series, studies, and patients.
        • Would be nice to save in another format such as NIFTI, but that is a nice-to-have.
        • Query/browse Qt widget would show results as a tree (patient, study, series, images) with optional keys (sex, etc), when available
        • Provide progress reporting of transfers
        • This would be HUGE for the community. Imagine having a small set of Qt/DCMTK widgets that combined together form a Q&R workstation. This is a great place to start sharing.
      • Goal2: slice-based view of downloaded data (data on disk)
        • Qt image viewer with intensity window/level and not much more. This is meant to be minimalistic.
      • Goal3: initiate processing on data (server-based data or downloaded data) using the dicom plug-in standard
        • This is where we can really help the community. Provide a C++ reference implementation, and some Qt widgets that help initiate calls to available services.

Organization and Workflow

  • First day will be dedicated to code organization and policies for git-based workflow.
    • expected result will be a set of procedures for dissemination to the ctk community for comment and adoption.

DICOM

  • Review of ITKv4 DICOM Plans and discussion of DCMTK and GDCM.

Widgets

  • Review status of Qt-based CTK widget developments
    • Slicer4, DTK, GoFigure (others?)

Plugins, Modules

(utilities for discovering and invoking code blocks)

Old:

  • Plugins: not-application dependent (like a java plugin that runs in firefox or internet explorer or in our case something like a registration routine that gets invoked from a host application)
  • Modules: rely on some of the API of the host application (like a loadable module that creates a custom GUI using a Qt API so it may work in more than one Qt-based application)

Interoperability

(gluing toolkits together)

  • VTK/OpenInventor shared OpenGL rendering context

Events and Communications

(run-time messaging within and among applications)

  • ZMQ
  • OpenIGTLink
  • Event Bus (MAF, Patrick's ZMQ)

Integration

(using CTK code in different applications)

  • Change the private implementation macros to behave like Qt (derivable pimples)
  • Improve unit testing macros (interactive mode, property check...)
