Tutorial 1 (09:30-10:30): Colour in Medical Imaging with a focus on laparoscopy

Tutors : Craig Revie (FFEI Limited) and Ole Jakob Elle (The Intervention Centre, Rikshospitalet, Oslo University Hospital)

Title :Colour in Medical Imaging with a focus on laparoscopy

Summary:  The Digital Imaging and Communications in Medicine (DICOM) specification which describes various imaging modalities and identify those which use colour imaging. Traditionally medical imaging has been monochrome but with the expansion of medical diagnostic technology there is an increasing use of colour and recognition by some of those most closely involved that there is a need to improve the way in which colour is handled. This tutorial will look at a wide range of applications including medical photography, dental and prosthetic surgery, ophthalmology. petri dish imaging, digital pathology and endoscopy / laparoscopy. It will also cover the more general topics of image processing, multi-spectral imaging, visualisation and display calibration which span a number of these applications. The first part of this tutorial will provide an overview that shows some of the colour requirements for each imaging modality and the second part will look in detail at some of the issues faced in laparoscopy.

Biography W Craig Revie :W Craig Revie is Principal Consultant at FFEI Limited and is responsible for the specification of software for imaging in the areas of Graphic Arts and Life Sciences, particularly in relation to colour. He was responsible for the specification of Fujifilm’s XMF Workflow and has led the Sierra project which aims to provide a calibration framework and materials for digital microscope systems. In addition to his responsibilities with FFEI, Craig represents Fujifilm and Fuji Xerox in the ICC, CIE and ISO TC130 standards groups.

Biography Ole Jakob Elle: Ole Jakob Elle was born in Arendal, Norway 12th of April 1967. He studied at Norwegian Institute of Technology from 1986-1990 at Department of Production and Quality Engineering and started a PhD in underwater robotics at Department of Cybernetics in collaboration with Department of Production and Quality Engineering in 1992. From 1996-1998 he worked as a product developer at Luxo ASA working with medical light systems. He joined The Intervention Centre at Rikshospitalet, Oslo University Hospital in 1998 to be a bridge between the product development department at Computer Motion in Santa Bargbara, CA, USA and the cardiac surgeon at the hospital within robotic surgery. The Intervention Centre is also his Current place of work, where he now is heading the section for Technology Research there. He holds a 20% position as Associate Professor at Department of Informatics, University of Oslo in the research group ROBIN (Robotics and Intelligent systems) Ole Jakob Elle defended his PhD in robotic surgery in 2004.

 

Tutorial 2 (1045-11:30): Spectral Image Reproduction: Workflow and Application

Tutor : Dr. Philipp Urban (Head of Competence Center 3D Printing Technology, Fraunhofer Institute for Computer Graphics Research IGD, Fraunhoferstr. 5, 64283 Darmstadt, Germany)

Title :Spectral Image Reproduction: Workflow and Application

Summary:  Conventional trichromatic imaging (i.e., RGB) can have a wide range of colorimetric accuracy and is always constrained by metamerism. For color-critical, scientific, and archival applications, trichromatic imaging is often insufficient. Spectral imaging alleviates these limitations. This short course overviews spectral capture, spectral color management, and spectral printing.

Benefits:

 Attendees will be able to:

• Understand the advantages and disadvantages of spectral imaging compared with trichromatic imaging

• List and compare different techniques of spectral imaging.

• Become familiar with the foundations of estimating spectral reflectance from multi-channel images.

• Learn about separation techniques for spectral reproduction.

• Comprehend the applications of spectral imaging for multi-ink printing and spectral color management.

Biography: Philipp Urban received the M.S. degree in mathematics from the University of Hamburg, Germany, and the Ph.D. degree from the Hamburg University of Technology, in 1999 and 2005, respectively. From 2006 to 2008, he was a Visiting Scientist with the Munsell Color Science Laboratory, Center for Imaging Science, Rochester Institute of Technology, Rochester, NY, USA, and headed afterward the Color Research Group at the Institute of Printing Science and Technology, Technische Universität Darmstadt, Darmstadt, Germany. Since 2013, he has been the Head of the Competence Center 3D Printing Technology with the Fraunhofer Institute for Computer Graphics Research IGD, Darmstadt. His research interests include spectral imaging, image quality, and material appearance reproduction.

Tutorial 3 (10:45-11:30): Illusory colors and what one can do with them

Tutor : Bruno Laeng (Department of Psychology, University of Oslo)

Title :Illusory colors and what one can do with them

Summary:  About 4% of the general population has a perceptual ability called synesthesia (e.g., seeing colors when listening to music). The talk will focus on grapheme-color synesthesia or the perception of colors when reading black-printed letters or numbers. Far from being a disturbance, these "illusory" colors confer some advantages in visual attention and memory tasks.

Biography :Bruno Laeng is professor in cognitive neuropsychology. He received his Bachelor in experimental psychology from Universitá La Sapienza (Roma, Italia) and a Ph.D. in biological psychology from The University of Michigan (Ann Arbor, Michigan, USA). He has previously held positions at the University of Bergen, University of Tromsø, University of Guelph (Canada), Harvard University (USA) and he has been a Clinical Research Fellow at the Massachusetts General Hospital, Boston (USA). At present, Bruno Laeng is Professor in Psychology, University of Oslo, Oslo, Norway.
