Patent number: 10188281Abstract: An observation system for viewing light-sensitive tissue includes an illumination system configured to illuminate the light-sensitive tissue, an imaging system configured to image at least a portion of the light-sensitive tissue upon being illuminated by the illumination system, and an image display system in communication with the imaging system to display an image of the portion of the light-sensitive tissue. The illumination system is configured to illuminate the light-sensitive tissue with a reduced amount of light within a preselected wavelength range compared to multispectral illumination light, and the image of the portion of the light-sensitive tissue is compensated for the reduced amount of light within the preselected frequency range to approximate an image of the light-sensitive tissue under the multispectral illumination.Type: GrantFiled: March 30, 2016Date of Patent: January 29, 2019Assignee: The Johns Hopkins UniversityInventors: Russell H. Taylor, Seth D. Billings, Peter L. Gehlbach, Gregory D. Hager, James T. Handa, Jin U. Kang, Balazs P. Vagvolgyi, Raphael Sznitman, Zachary Pezzementi

Patent number: 8588509Abstract: We presented an approach for speeding-up image acquisition when tasked with localizing specific structures in FIB-SEM imagery. It exploits the fact that low-quality images can be acquired faster than higher-quality ones and yet be sufficient for inference purposes. We have demonstrated greater than five-fold speed-ups at very little loss in accuracy in the context of mitochondria and synapse detection. Furthermore, the algorithm we propose is generic and applicable to many imaging modalities that allow trading quality for speed.Type: GrantFiled: June 28, 2012Date of Patent: November 19, 2013Assignee: Ecole Polytechnique Federale de Lausanne (EPFL)Inventors: Pascal Fua, Graham Knott, Raphael Sznitman, Aurelien Lucchi
