Consortium for Electrocardiographic Imaging (CEI) events and activities: Updates and Invitations
Dana Brooks
Dear CEI participants:
This note is to give you all a quick update on CEI activities and
events, and in particular to invite you all to attend the CEI
satellite meeting to be held the day before the Functional Imaging
and Modeling of the Heart Conference this June in Bordeaux France:
- CEI satellite 5 June, http://www.ecg-imaging.org/community/events/cei-symposium-2019,
- FIMH 6-8 June, https://fimh2019.sciencesconf.org/
Note that separate registrations are required for the two meetings. More detail on the CEI satellite meeting is given below.
=====
What else is in this email:
In addition to the satellite meeting, CEI participants have been
actively working in our on-going workgroups.
Please join those activities by submitting your results to our
collaborative processing activities and joining the workgroup
meetings as described below. Note that some CEI workgroup
collaborative activities use the Covalic system; there are some
comments on Covalic use at the end of this email.
The latest details can usually be found on the CEI website, http://www.ecg-imaging.org. There is also a google calendar showing CEI meetings, deadlines, and conferences linked from that webpage, at http://www.ecg-imaging.org/subscribe/ceimeetingcalendar

I. CEI Satellite Meeting:
This is an exciting time for investigating the clinical potential
of CEI, with two commercial vendors and several recent, somewhat
conflicting, reports in the literature. The satellite meeting will
feature a mixture of clinical and engineering presentations as
well as time for open discussion. To date we have multiple
confirmed speakers now, including two ECGI-minded clinicians:
Hubert Cochet [Bordeaux] and Uyen Nguyen [Maastricht]). More
details will be announced over the coming weeks on the CEI
website, http://www.ecg-imaging.org.
The organizing committee is Matthijs Cluitmans (Maastricht U and Philips), Laura Bear (LIRYC), Jess Tate (U Utah) and Brian Zenger (U Utah).
====II. Signal Processing Workgroup
The signal preprocessing workgroup has started two new subgroups,
on interpolation and signal averaging.
1. Interpolation – The goal of this group is to study
interpolation of body surface potentials and its impact on ECGI.
This includes finding optimal interpolation methods and learning
how to identify regions where interpolation would be
beneficial/detrimental to the inverse problem. If you would like
the be involved with this subgroup e-mail Prof.Yesim Serinagaoglu,
yse...@metu.edu.tr. The
next meeting of this group is on 21 March at 15:00 CET. Contact
Dr. Serinagaoglu for information on how to join the meeting. (Note
there will be1 hour less difference than usual with the US due to
differences in the date of transition to summer time between
Europe and the US).
2. Signal Averaging – The goal of this group is to study signal
averaging methods in relation to ECGI. This includes finding the
best methods for preprocessing, beat segmentation, clustering and
alignment, assessing the impact of potentially correlated noise
(i.e. geometric error or respiratory
noise) and how to counteract these effects.If you would like the
be involved with this subgroup e-mail Dr. Jaume Coll-Font, jcol...@gmail.com. The
next meeting of this group is on 20 March at 15:00 CET. Contact
Dr. Coll-Font for information on how to join the meeting. (See
note above on Europe / US time difference.)

III. Activation / Recovery Time Estimation Workgroup
This workgroup has been developing datasets that participants can use to compare estimation of activation and recovery times from surface potential measurements. New ECGI-reconstructed surface potential signals have recently been made available on Covalic (https://challenge.kitware.com/#challenge/5b44770756357d05219fa8e3, Phase 2, Setup 1-3). We are planning to prepare a CinC abstract based on results for these new data so we encourage you to give it a try! The deadline for submitting results to Covalic for this CinC contribution is Monday, March, 25. The next workgroup meeting will be on Tuesday, March, 26, 16:00 CET. (See note above on Europe / US time difference.) For more information on this workgroup contact Steffen Schuler, steffen...@kit.edu

IV. PVC Localization Workgroup
The PVC workgroup has recently uploaded two clinical datasets to
Covalic, one from Dalhousie University and the other from
Karlsruhe Institute of Technology, for interested groups to use to
try out PVC localization methods. We are interested in comparing
results obtained using any method, including activation-based, TMP
based, surface potential based, dipole based, or any other
approach. The goal is to synthesize results and publish
comparisons based on them. The link to this dataset on Covalic is
https://challenge.kitware.com/#phase/57571091cad3a51cc63468df.
We request responses be uploaded to Covalic by May 1.
====
V. Atrial Fibrillation Workgroup
This workgroup has two subgroups, one working on algorithms for atrial-ventricular cancellation and the other on source localization for atrial fibrillation.
1. Updates on AA-ventricular cancellation subgroup
Pietro Bonizzi from Maastricht is leading this group on working
with ventricular cancellation algorithms for electrogram signals.
They are also systematically comparing electrogram
cancellation algorithms. Contact Pietro for more information at pietro....@maastrichtuniversity.nl
2. Updates on AA-source location subgroup: Techniques for
noninvasive (ECGI) AF driver location
Miguel Rodrigo from Madrid / Valencia is working on a new version of a document which will incldue activation time algorithms to be discussed in the next meeting. Contact Miguel at miro...@gmail.com for more information.
The group has also been actively discussing a recent publication
from the Bordeaux group (Duchateau et al) ECGI paper.
The next meeting will be April 17th 15:00 CEST.
====
VI. Other CEI Activities
There are two other workgroups currently being formed, one on integration with clinicians (concentrating at the moment on the Bordeaux satellite meeting) and one looking at developming a software platform for integration of different algorithmic approaches into a framework pipeline, probably using the SCIRun software. Jess Tate of University of Utah (je...@sci.utah.edu) and Eelco van Dam of PEACS, NL (eelco....@peacs.nl) are leading this effort.

VII. Comments on Use of Covalic
Use of Covalic: as noted in several of the workgroup activity descriptions above, we are using the Covalic platform for collaborative algorithmic activity on shared data, https://challenge.kitware.com/#challenges. Covalic can present some challenges of its own so we recommend:
1. Pay close attention to all details such as naming conventions of files when submitting solutions, and
2. Do not hesitate to contact the leader of the relevant workgroup if you have difficulty with using Covalic.
