Abstract:

Image-guided intervention techniques are replacing traditional intervention, surgery, and invasive procedures with minimally invasive techniques that incorporate medical imaging to guide the intervention. Patients prefer these procedures to open surgeries and interventions because they are typically less traumatic to the body and result in faster recovery times. Despite its many merits, image guided intervention procedures are challenging due to restricted views and depth perception, limited mobility and maneuvering of surgical instruments, and poor tactile feedback in some instances, which make it difficult to palpate organs. Virtual simulators and planning systems are powerful tools that allow clinicians to practice and rehearse their surgical and procedural skills in a risk-free environment. Software is an integral part of these virtual simulators and planners. Whether it is for interfacing with a tracking device to collect position information from surgical instruments, integrating intra-operative and pre-operative images, controlling and guiding robots or generating a 3D visualization to provide visual feedback to the clinician, software has a critical role. Open source software is playing a major role in increasing the pace of research and discovery in image-guided intervention systems by promoting collaborations between clinicians, biomedical engineers, and software developers across the globe. Kitware, Inc., a leader in the creation and support of open-source scientific computing software is at the forefront of this type of effort. In this talk, I will provide an overview of image guided intervention system and discuss two NIH funded image guided intervention training projects currently led by Kitware: 1) A simulator that trains clinicians to improve procedural skill competence in real-time, ultrasound-guided renal biopsy and 2) An interactive, patient-specific virtual surgical planning system for upper airway obstruction treatments.

Abstract:

Situated language interaction is a complex, multimodal affair that extends well beyond the spoken word. When interacting, we use a wide array of non-verbal signals and incrementally coordinate with each other to simultaneously resolve several problems: we manage engagement, coordinate on taking turns, recognize intentions, and establish and maintain common ground as a basis for contributing to the conversation. Proximity and body pose, attention and gaze, head nods and hand gestures, prosody and facial expressions, all play very important roles in this process. And just like a couple of decades ago advances in speech recognition opened up the field of spoken dialog systems, current advances in vision and other perceptual technologies are again opening up new horizons — we are starting to be able to build machines that computationally understand these social signals and the physical world around them, and participate in physically situated interactions and collaborations with people.

 

In this talk, using a number of research vignettes from work we have done over the last decade at Microsoft Research, I will draw attention to some of the challenges and opportunities that lie ahead of us in this exciting space. In particular, I will discuss issues with managing engagement and turn-taking in multiparty open-world settings, and more generally highlight the importance of timing and fine-grained coordination in situated language interaction. Finally, I will conclude by describing an open-source framework we are developing that promises to simplify the construction of physically situated interactive systems, and in the process further enable and accelerate research in this area.

 

Bio:

Dan Bohus is a Senior Principal Researcher in the Adaptive Systems and Interaction Group at Microsoft Research. His work centers on the study and development of computational models for physically situated spoken language interaction and collaboration. The long term question that shapes his research agenda is how can we enable interactive systems to reason more deeply about their surroundings and seamlessly participate in open-world, multiparty dialog and collaboration with people? Prior to joining Microsoft Research, Dan obtained his Ph.D. from Carnegie Mellon University.

Abstract:

Vision-based surgical instrument segmentation, which aims to detect instrument regions in surgery images, is often a critical component for the computer or robot-assisted surgical systems. While advanced algorithms including deep CNN models have achieved promising instrument segmentation results, several limitations remain unsolved: (1) The robustness and generalization ability of existing algorithms is still insufficient for challenging surgery images, and (2) deep networks usually come with high computation cost, which needed to be addressed for time-sensitive applications during surgery. In this talk, I will present two algorithms to address these challenges. First, I will introduce a lightweight CNN that can achieve better segmentation performance with less inference time on low-quality endoscopic sinus surgery videos compared with several advanced deep networks. I will then discuss a domain adaptation method that can transfer the knowledge learned from relevant and labeled datasets for instrument segmentation on an unlabeled dataset.
