February 28, 2017 | Oncologists and radiotherapists get new software

list barat outil logiciel​List, a CEA Tech institute, recently developed a new software application that helps oncologists and radiotherapists diagnose tumors, plan treatment, and predict the patient’s response.

The new software combines data from different medical imaging techniques (MRI, PET, and other scans) using a non-supervised statistical analysis to characterize various types of tumor tissue, providing oncologists and radiotherapists with valuable assistance diagnosing tumors and planning radiotherapy treatments.

The tumor and organ edges are automatically located and active areas of the tumor are distinguished from necrotic tumor tissue and zones of edema. “The software uses statistical analysis methods to perform a 3D segmentation of the tissue, giving each type of tissue its own unique signature,” explained a List researcher. “This gives practitioners a basis for identifying tissue. The practitioner can then either approve or correct the results as needed. This saves time and provides a more objective assessment than manually segmenting the tumor slice by slice.”

The software also delivers benefits for patient monitoring by providing quantitative data on tumor growth and identifying new tumor markers. For example, the software can be used to determine tissue signatures for the early detection of recidivism in glioblastoma patients, as well as for any other type of pathology.

February 9, 2017 | Gerim 2 offers X-ray tomography-based non-destructive testing

controle non destructifList, a CEA Tech institute, is investigating ways to increase the use of X-ray tomography in non-destructive testing (NDT). The institute’s Gerim 2 platform has a new robotic cell to help further this research.

X-ray tomography is a high-resolution imaging technique used for the non-destructive testing of sensitive parts. However, because the technique is difficult to implement, it had, until now, been used only to inspect small parts, due to the fact that the parts must be placed on a rotating platform between a fixed X-ray source and detector.

To use the technique on larger parts and, ultimately, right at the inspection site, List developed a new robotic inspection cell at its Gerim 2 platform. The cell’s major innovation is that the X-ray source and detector are no longer fixed. They are mounted on robotic arms, which move around the part being inspected, which remains fixed. “The main development here was advanced algorithms to reconstruct tomographic images generated by non-standard trajectories with limited viewing angles,” explained a List researcher. “We improved the trajectories and made sure that the effects of robot positioning errors on the 3D reconstruction were taken into account when assessing the cell’s performance.”

The trajectory simulation and 3D reconstruction developments achieved have all been integrated into List’s CIVA software and will be validated during a series of tests. Industrial R&D partners can access the resources of the Gerim 2 platform, which opened in March 2016 at Paris-Saclay, for their emerging robotized X-ray imaging R&D needs.

January 13, 2017 | Deep learning for better audio and video content archiving

analyse semantiqueCEA Tech institute List recently worked with France’s national television broadcasting company to develop an automated, real-time analysis system to facilitate audio and video content annotation

Manually annotating audio and video content does not generally provide complete or consistent enough information. France's national television broadcasting company turned to List to come up with solution to get more out of its content. List leveraged its strong know-how in deep learning for image recognition to develop a tool capable of automatically identifying nearly 15,000 people and around 20 different sports in real time. The institute completed a demonstration of its semantic analysis tool for videos on footage of the 2016 French Open tennis tournament.

List's researchers started with a neural network that was already capable of identifying 2,000 different faces. They added a learning layer to the network to increase the number of faces to what was required for the project. "We searched the internet for images of the 15,000 people on our partner's list and we integrated them into the system," said a List researcher. "This brought our image recognition rate to 95% and gave us a model that we can expand as needed." The researchers also developed a tool to identify around 20 different sports from video footage.

France's major broadcasting companies have expressed interest in List's semantic analysis tools, so there should be ample opportunity to take the results of these advances even further!

Convergence pour l’industrie du futur : un vrai succès !

convergence cea aifDu 6 au 9 décembre 2016 s’est déroulée la première édition de « Convergence pour l’industrie du futur », évènement rassemblant les acteurs majeurs français et européens de la thématique, dont le CEA.

Inauguré par le Président de la République François Hollande, ce nouvel évènement qui réunissait pour la première fois les salons Midest, Smart Industries et le forum Industrie du Futur a été un franc succès. Au total 1800 exposants et 42000 professionnels se sont retrouvés au Parc des Expositions de Paris Nord Villepinte.

 

Le CEA, membre fondateur de l’Alliance Industrie du Futur, a présenté 9 démonstrateurs technologiques sur 2 espaces (CEA et Alliance Industrie du Futur) et a participé à 4 tables rondes. La startup ISYBOT a également annoncé sa création le 8 décembre lors d’un événement organisé sur le stand de l’Alliance Industrie du Futur.
