2. PRIMAGE is one of the largest and more ambitious European research projects in
medical imaging, artificial intelligence and childhood cancer.
The project is funded with 10 million euros by the European Commission, 16 European
institutions are participating in the consortium and has an implementation duration of
4 years. Internationally recognized researches in in-silico technologies and clinical
experts in pediatric cancer are part of the staff of PRIMAGE.

What is PRIMAGE?

3. PRIMAGE proposes a
cloud-based platform
to support decision
making in the clinical
management of
malignant solid
tumors, offering
predictive tools based
on the use of novel
imaging biomarkers, in-
silico tumor growth
simulation and
machine-learning.

What is PRIMAGE?
PRIMAGE project is devoted at developing methods of computational analysis of medical images
applied to child cancer.

● Model training is computationally
intensive and requires GPUs.
● A Data Scientist (DS), writes the code
for the training and error estimation of
the classifier and stores it (1) in a
private repository.
● The commit triggers (2) the autobuild
system to build a container image (3),
which is stored in the private registry.
● The DS submits the training job (4).
● The application runs on the tagged
resources provided of GPUs (5) which
pull the images (7) and gets the data
on a volume mounted from the shared
storage (6).
● At the end of the process, the output
model is stored in the shared storage,
accessible from the user’s console (8).

PRIMAGE aims at developing state-of-the-art and cutting-edge research tools for
building up clinical decision support systems.
Such research tools will leverage HPC resources and cloud infrastructures for their
development and operation.
PRIMAGE is a clinical-led project technically coordinated by an SME leading the
application of AI technologies in medicine.
