IMAGING AND RADIOLOGY


Radiology Assistant

This is one of the best teaching sites for Radiology. The educational site was launched and hosted by The Radiological Society of the Netherlands. It was launched as a non-profit organisation to provide education in radiology. The site was the brain child of Robin Smithuis and the subjects are now presented by many experts in the field. The English text is edited by Marieke Hazewinkel and Jennifer Bradshaw.

Although the site was started to help medical care in South East Asia, it is a brilliant site to educate young residents as well as any radiologist willing to learn anywhere in the world.The site covers a wide range of topics and will help the doctors to learn and interpret the findings on x-ray, CT Scan and MRI scan.Being an Orthopaedic Surgeon I was particularly impressed with what is presented under musculoskeletal system and spine (under Neuroradiology).


Femto photography - The future of Imaging Technology

Ramesh Raskar


In 1964 MIT professor Harold Edgerton, pioneer of stop-action photography, famously took a photo of a bullet piercing an apple using exposures as short as a few nanoseconds. Inspired by his work, Ramesh Raskar and his team set out to create a camera that could capture not just a bullet (traveling at 850 meters per second) but light itself (nearly 300 million meters per second).

 

Ramesh Raskar joined the Media Lab from Mitsubishi Electric Research Laboratories in 2008 as head of the Lab's Camera Culture research group. His research interests span the fields of computational photography, inverse problems in imaging, and human-computer interaction. Recent inventions include transient imagingto look around a corner, a next-generation CAT-scan machine, imperceptible markers for motion capture (Prakash), long-distance barcodes (Bokode), touch + hover 3D interaction displays (BiDi screen), low-cost eye care devices (NETRA) and new theoretical models to augment light fields (ALF) to represent wave phenomena.

 

Here he presents femto-photography, a new type of imaging so fast it visualizes the world one trillion frames per second, so detailed it shows light itself in motion. This technology may someday be used to build cameras that can look round corners or see inside the body without X-rays.

 

Photography is about creating images by recording light. At the MIT media lab, professor Ramesh Raskar and his team members have invented a camera that can photograph light itself as it moves at, well, the speed of light

 

Ramesh Raskar qualified as an engineer from the Govt College of Engineering, Pune, India. Did his M.S. Computer Science at the University of Iowa and obtained his Ph.D in Computer Science from the University of North Carolina at Chapel Hill
