Motivated by improved outcomes and lower overall costs, clinical practice has replaced many traditional procedures with minimally invasive ones. Performing these procedures is significantly more challenging due to reduced visual and tactile feedback. Computer Aided Intervention systems aim to augment the clinician's abilities by providing virtual or augmented views as navigational guides, or by utilizing robots to align tools to prescribed poses. Two challenges associated with adoption of CAI systems include high financial costs and complex clinical workflows. In the first part of this talk we will present a registration framework, using consumer grade RGBD cameras for intraoperative point cloud acquisition, in the context of neurosurgery, as a way to address these challenges. We evaluate two cameras, the Microsoft Kinect v1 and the Sense from Sense3D. We show that they provide similar, clinically acceptable, registration accuracy on the order of 2mm RMSE. In the second part of this talk, we will introduce the SimpleITK toolkit, a simplified open source interface to the Insight Segmentation and Registration Toolkit (ITK), developed at the National Library of Medicine. This modified interface is implemented in C++ with bindings available for several popular programing languages including: Python, R, Java, Lua, Ruby, Tcl and C#. The intent of SimpleITK is to allow non-expert programmers to take advantage of the rich set of algorithms available in ITK. We will illustrate the use of SimpleITK components in a live demonstration using the Python programming language and provide references to the freely available resources associated with the toolkit.

He obtained his Ph.D. in computer science from The Hebrew University of Jerusalem, Jerusalem Israel, in 2004. From 2006 to 2011 he was an assistant professor in the department of radiology, Georgetown university, and from 2011 to 2014 he was a principal investigator at Children's National Hospital in Washington DC. He is a member of the MICCAI society and a senior member of the IEEE society. He was chair of SPIE Medical Imaging: Image-Guided Procedures, Robotic Interventions, and Modeling (2013-2016) and is the program chair for the Information Processing in Computer Assisted Interventions (IPCAI) 2016 conference. He believes in the open science approach to conducting research, actively supporting the development of open source software, and has lead and contributed code to multiple medical toolkits including the Image-Guided Surgery Toolkit (IGSTK), the Insight Registration and Segmentation toolkit (ITK), SimpleITK, and the Public software Library for UltraSound imaging (PLUS).
