Radioactive astronauts: images worth a thousand experiments.

Google Tech Talks April, 22 2008 ABSTRACT Cosmic radiation presents a very real threat to astronauts. As part of a NASA funded project to evaluate the cancer risks of a trip to Mars, Dr. Costes' team has been collecting hundreds of gigabytes of 3D and 4D imagery showing the traversal of cosmic particles in human cells, and characterizing the DNA damage along those tracks to reveal the existence of DNA repair factories. In addition to sharing his project with us, Dr. Costes will discuss how they've overcome some of the challenges in 3D image registration and segmentation, pattern recognition and classification, and storing, organizing and browsing through thousands of images and experimental measurements. Speaker: Sylvain Costes Dr. Costes is a principal investigator in the Life Sciences Division of the Lawrence Berkeley National Laboratory.
