Technological challenges in Positron Emission Tomography: a physicist’s perspective

Coloquio excepcional - invitado del programa Maldacena.

Fecha y Horario:

19 de noviembre de 2019, 14:30hs

Orador:

Dr. Claude Comtat

Afiliación:

Atomic Energy and Alternative Energies Commission (CEA) · Frédéric Joliot Institute for Life Sciences –Paris – Saclay Multimodal Biomedical Imaging Lab (Biomaps)

Resumen:

Positron Emission Tomography (PET) is a molecular imaging technique, which allows the in vivo measurement of biological processes at the molecular and cellular level. It is based on the injection of a molecule labelled with a b+ decaying radionuclide that targets a biological process of interest and the detection of the resulting pairs of gamma photons. PET plays an important not only in clinical applications (mostly in oncology), but also in drug development and in biomedical research. It is a rapidly evolving technique, thanks to the joint efforts of chemists, physicists, mathematicians, computer scientists, engineers, biologists, pharmacologists, and physicians. The objective of the talk is to give an overview of current challenges in the development of new detectors and new data processing methods to further improve the sensibility and the accuracy of PET. This will include, in particular, hybrid imaging, total-body imaging, the 10-picosecond challenge, parametric imaging, machine learning.

Minibio:

El Dr. Comtat es físico graduado de laEcole polytechnique fédérale de Lausanne, y Doctor en Física de Alta Energía por dicha Universidad. Trabajó como investigador en el servicio de medicina nuclear-PET del Centro Médico de la Universidad de Pittsburgh, junto con el Dr. Paul E. Kinahan, reconocido pionero en física de PET. Trabajó en el Hospital Frédéric Joliot (Orsay, Francia), donde continúa sus investigaciones en el campo de reconstrucción de imágenes, modelación de cerebro y oncología en PET, así como también en aplicaciones farmacológicas en PET/MR. Desde 2015, es miembro destacado del laboratorio de In Vivo Molecular Imaging.
