IPCAI 2020- Program

Dear colleagues,

We are pleased to welcome you to IPCAI 2020 which will take place from June 23-24, 2020, in conjunction with the Computer Assisted Radiology and Surgery (CARS) Congress. In light of the ongoing COVID-19 pandemic, IPCAI 2020 will be held as a fully virtual conference. The virtual conference platform is now available on the IPCAI website for everyone to explore the IPCAI 2020 program, and the virtual conference

characteristics. This year, the conference comprises the following components:

IPCAI paper presentations: For all IPCAI papers accepted at this year's conference, short 10 min presentations will be pre-recorded and be available on the conference platform. Selected papers will be presented in two live sessions: (1) “Selected Short Paper Presentations” which will include short presentations (10mins long) of regular papers voted by the conference delegates and the ACs, followed by a moderated live question/answer session. (2) “Selected Long Paper Presentations” which will include long presentations (20mins long) of regular papers shortlisted for an award by the IPCAI 2020 Award committee, followed by a moderated live question/answer session.

IPCAI paper and long abstract discussions: The “Online Town” will be used to host the “Regular Paper Town” and “Long Abstract Town” sessions where the conference delegates will have the opportunity to connect live to the presenting authors of each regular paper and long abstract, respectively.

Interactive sessions: The “Ask me anything” session has been introduced this year which will be a live session led by members of the IPCAI 2020 Steering Committee and ACs from academia and industry. The conference delegates will have the opportunity to ask in advance questions to be discussed during this session. More details can be found on the Virtual IPCAI website. Also, the “IPCAI Town” will allow the conference delegates to socialise and play the IPCAI quiz. Each paper will have a dedicated RocketChat channel to allow the communication between the delegates and the authors.

Keynote lectures: The CARS keynote lectures will be held live with question/answer options.

Voting and feedback: The conference delegates will have the opportunity to vote for short presentations to be presented during the “Selected Short Paper Presentation” session, vote for the best short presentation which will receive the audience award, and provide their feedback. More details can be found on the Virtual IPCAI website.

All the sessions have been scheduled in the time-zone of the hybrid CARS conference and in a time slot that will maximize world-wide attendance. To accommodate the delegates who can not participate within healthy working hours due to time zone issues, all the pre-recorded videos will be available on the website for registered users. To register for the conference, special registration and group registration fees are applicable at

The organizing team is committed to make IPCAI 2020 a vibrant and interactive virtual conference with exciting sessions which will welcome participants from all over the globe.

We look forward to seeing you there!
With our best regards
