Workshop program (September 14th, 2014)

The workshop will start with the presentation and distribution of the onsite testing datasets (15 new patients) and the start of the challenge. For the remainder of the morning session, participants will run their algorithms on this data. The organizers will evaluate the results with reference data during the lunch break. After lunch, we intend an invited lecture and a set of selected talks (based on the pre-workshop results). Following these presentations, we will have a poster session, where the participants can explain their algorithm, possibly including on-site demos. The afternoon session will conclude with a presentation of the challenge results, and a town hall discussion.

Guest speaker

The workshop organizers are honored to welcome Dr. A. Papachristidis, a world class echocardiologsit expert that has been involved in the challenge (along with two others cardiologists) to define the manual references of the whole database.

Biography of Dr. A. Papachristidis

Dr. Alexandros Papachristidis is a Clinical Fellow in Pacing and Echocardiography at King’s College Hospital, London, UK. He trained at the Medical School of National and Kapodistrian University of Athens, Greece and was qualified as a Specialist Cardiologist in 2011. He has a special interest in Echocardiography and Cardiac Pacing and particularly in 3D echocardiography, left ventricular dyssynchrony assessment and cardiac ressynchronization therapy.

Prizes

During the on-site workshop, the testing 2 dataset will be processed by the participating teams. The methods will be ranked according to two sub-categories: the semi-automatic and the fully automatic approaches. The final score will be calculated as the mean value of the scores obtained from each testing dataset (average value of the global score obtained from the Testing 1 and Testing 2 dataset). For each sub-category, a diploma will be awarded to the challenger that obtained the best global score.

Finally, the team that will obtain the best score from all the participants (whatever the sub-category) will be rewarded by a life-size human heart model, sponsored by Materialise cie. A photo of this model is given above.
