Speaker: Prof. Samuel Kadoury, Ph.D., P.Eng., Polytechnique Montreal, Canada Research Chair in Medical Imaging and Assisted Interventions
Spinal deformities such as adolescent idiopathic scoliosis are complex 3D deformations of the musculoskeletal trunk. For the past two decades, 3D spine reconstructions obtained from diagnostic scans have assisted orthopedists assess the severity of deformations and establish treatment strategies. However, these procedures required significant manual intervention and were not suited for routine clinical practice. This presentation will expose computational methods recently developed in our lab based on machine learning and statistical analysis to automatically reconstruct the personalized spine geometry from X-rays, classify various deformation patterns in 3D, predict disease progression and perform intra-operative guidance during surgical procedures, with the use of biomechanical simulation models and multi-modal registration. Experiments performed at the CHU Sainte-Justine Hospital on adolescent patients demonstrate the potential clinical benefit of capturing statistical variations in the spine geometry to help diagnose and treat this disease.

He completed a post-doctoral fellowship at Ecole Centrale de Paris and was a clinical research scientist for Philips Research at the National Institutes of Health, developing image-guided systems for liver and prostate cancer. Dr. Kadoury has published and presented his work in a number of conferences and journals such as Radiology, ISMRM, IEEE TMI, Medical Image Analysis, MICCAI and IPCAI, and served as Area Chair for conferences such as MICCAI and CVPR. He has also been granted five international and US patents the field of image-guided interventions and is co-recipient of the NIH merit award and the RSNA Cum Laude Award for his work in artificial intelligence for liver cancer detection.
This presentation will discuss how symmetric and asymmetric motions can be used for training and rehabilitation. Many daily tasks require that a person use both hands simultaneously, such as moving a large book or opening the lid on a jar. Such bimanual tasks are difficult for people who have a stroke, but the tight neural coupling across the body has been hypothesized to allow individuals to self-rehabilitate by physically coupling their hands. The interaction discussed here separates the task and guidance forces by guiding one hand so the user can actively recreate the motion with their other hand that receives task-related forces. This method is based on the ability of humans to easily move their hands through similar paths, such as drawing circles, compared to the difficulty of simultaneously drawing a square with one hand and a circle with the other. Experiments were performed to characterize the reference frames, interaction stiffnesses, and trajectories that humans can recreate.
The second half of this presentation will focus on gait rehabilitation for individuals with asymmetric impairments. Asymmetric gait is caused by many impairments, such as leg-length discrepancy, prosthetics, and stroke. Using a model of gait based on kinematic synchronization, it is shown that some types of symmetry can be generated in a person with an asymmetric impairment, but not simultaneously in both motions and forces. To balance the limitation of always having some asymmetries, perception of gait is used to put limits upon what appears symmetric even if it is not perfectly symmetric. One rehabilitation method, the Gait Enhancing Mobile Shoe (GEMS), uses an exaggerated asymmetric motion to generate an after-effect that has a better walking pattern. The GEMS uses a Kinetic Shape wheel to passively redirect the user’s natural downward forces while walking into a backward motion that generates a corrective after-effect. The Kinetic Shape has also been applied to the tip of a walking crutch to assist in locomotion. At the conclusion of this talk, you should have a better understanding of the symmetries and asymmetries that exist in your daily motions.

Steered particles offer a method for targeted therapy, interventions, and drug delivery in regions inaccessible by large robots. Magnetic actuation has the benefits of requiring no tethers, being able to operate from a distance, and in some cases allows imaging for feedback (e.g. MRI). However, for MRI and setups where the distances between external magnets are much larger than the robot workspace, the magnetic field is approximately uniform across the workspace. Moreover, the system is severely under-actuated when there are more particles than control inputs. In my talk I’ll share tricks we use to overcome this underactuation for coverage, manipulation, self-assembly, and steering large numbers of particles. You can help — visit http://swarmcontrol.net and play some games.
Aaron Becker’s passion is robotics and control. Currently as an Assistant Professor in Electrical and Computer Engineering at the University of Houston, he is building a robotics lab. NSF selected Aaron for the CAREER award in 2016 to study massive manipulation with swarms: using a shared input to drive large populations of robots to arbitrary goal states. Becker won the Best Paper award at IROS 2014. As a Research Fellow in a joint appointment with Boston Children’s Hospital and Harvard Medical School, he implemented robotics powered and controlled by the magnetic field of an MRI. As a Postdoctoral Research Associate at Rice University, Aaron investigated control of distributed systems and nanorobotics with experts in the fields. His online game http://swarmcontrol.net seeks to understand the best ways to control a swarm of robots by a human. The project achieves this through a community of game-developed experts. Aaron earned his PhD in Electrical & Computer Engineering at the University of Illinois at Urbana-Champaign.
Often within the clinical domain, the practical translation of computational modeling for therapeutic benefit is criticized as being idealized or not compatible with real clinical practice. As a result, the integration of these powerful approaches within the workflow of procedural medicine has been diminished. However, with continued improvements in computing and instrumentation, the ability to translate complex models from idealized prospective predictive roles to ones that are more integrated within therapeutic and novel imaging frameworks is becoming a rapid reality. Recent advances in biophysical model-embedded systems designed to enable novel soft-tissue surgical/interventional applications are an excellent example and will be explored in this talk. The paradigm suggested is that procedural precision medicine should not be limited to only the use of patient data (e.g. imaging, biomarkers, physiological variables, etc.) for staging and conventional guidance, but, in addition, it should also serve as a patient-specific scaffold that when combined with advanced computation and instrumentation can add new enhanced capabilities to therapeutic guidance and delivery. This is a paradigm that challenges convention because it advocates a more collaborative intraoperative patient care environment with diverse teams of engineers, scientists, and physicians working together to best meet therapeutic procedural goals.

He received his Ph.D. from Dartmouth College in Engineering with Biomedical Specialization in 1998. The focus of his doctoral research was on computational biomechanical models of the brain for surgical applications. He stayed on for a post-doctoral training experience continuing that work and initiating projects in areas of inverse problems (elastography and epileptogenic source localization). He joined the faculty at Vanderbilt University in the Spring of 2001 and is currently Vanderbilt’s Harvie Branscomb Professor. He is a Professor of Biomedical Engineering with appointments in Radiology and Radiological Sciences, and Neurological Surgery. He is director of the Biomedical Modeling Laboratory, co-founder of the Vanderbilt Institute for Surgery and Engineering (VISE, www.vanderbilt.edu/vise ). He was a co-inventor of the first FDA approved image-guided liver surgery system. He is currently PI on several NIH research grants concerned with model-enhanced image-guided brain, liver, kidney, and breast surgery. He is also involved in modeling efforts for predictive forecasting in neoadjuvant chemotherapy outcomes for breast cancer, and differentiating brain tumor radio-necrosis from recurrence in radiosurgery. In addition, he recently created a novel NIH-T32 training program focused at training engineers to create novel technology platforms for treatment and discovery within surgery and intervention. Dr. Miga is also an American Institute for Medical and Biological Engineering Fellow and an Associate Editor for the Journal of Medical Imaging. He has also served extensively on NIH panels to include being a former charter member of the Biomedical Imaging Technology (BMIT) study section, and recently taking on a new charter member role with the Bioengineering, Technology, and Surgical Sciences (BTSS) study section. His research interests are in computational modeling for surgical and interventional applications, inverse problems in therapeutics and imaging, and image-guided surgery.
It is well-established that surgical care directly affects patients’ quality of life, and that poor quality surgical care increases the risk of death and other severe complications. The process of ensuring high quality surgical care begins with educating, efficiently training, and credentialing competent surgeons. While there is currently no global consensus for surgical competency, most definitions refer to the level of skill required to safely perform a particular procedure. Most tend to think of surgical competency as relating to both technical and non-technical skill as well as judgment during a procedure, and so being able to assess and, more importantly, improve on each of these aspects ultimately drives the quality of surgical care that exists throughout the healthcare system. This talk will focus on the use of current technology available to train surgeons and explore new research strategies in computer science to improve training.

Last Seminar of the Semester.
Locomotion and perception are a common thread between robotics and biology. Understanding these phenomena at a mechanical level involves nonlinear dynamics and the coordination of many degrees of freedom. In this talk, I will discuss geometric approaches to organizing this information in two problem domains: Undulatory locomotion of snakes and swimmers, and vibration propagation in spider webs.
In the first section, I will discuss how differential geometry and Lie group theory provide insight into the locomotion of undulating systems through a vocabulary of lengths, areas, and curvatures. In particular, a tool called the *Lie bracket* combines these geometric concepts to describe the effects of cyclic changes in the locomotor’s shape, such as the gaits used by swimming or crawling systems. Building on these results, I will demonstrate that the geometric techniques are useful beyond the “clean” ideal systems on which they have traditionally been developed, and can provide insight into the motion of systems with considerably more complex dynamics, such as locomotors in granular media.
In the second section, I will turn my attention to vibration propagation through spiders’ webs. Due to poor eyesight, many spiders rely on web vibrations for situational awareness. Web-borne vibrations are used to determine the location of prey, predators, and potential mates. The influence of web geometry and composition on web vibrations is important for understanding spider’s behavior and ecology. Past studies on web vibrations have experimentally measured the frequency response of web geometries by removing threads from existing webs. The full influence of web structure and tension distribution on vibration transmission; however, has not been addressed in prior work. We have constructed physical artificial webs and computer models to better understand the effect of web structure on vibration transmission. These models provide insight into the propagation of vibrations through the webs, the frequency response of the bare web, and the influence of the spider’s mass and stiffness on the vibration transmission patterns.

Dr. Hatton is the recipient of a 2017 NSF CAREER award to further his work in the dynamics of locomotion.
Microsurgical resection, endovascular means and stereotactic radiotherapy are the major treatments of cerebral arteriovenous malformations (AVM) and each method has its own limitations. Preoperative fractionation embolization can reduce bleeding and surgical risk, however, patients have to experience repeated pain due to the repeated treatments, and face the risk of rupture of AVM during treatment. The purpose of this study is to evaluate the advantages and safety of combined surgical and endovascular. One hundred and ninety-five patients were successfully completed with combination of endovascular therapy and craniotomy in the hybrid operating room from February 2016 to July 2017 in Beijing Tiantan Hospital. We get our initial experience of combined surgical and endovascular procedures in hybrid operating room (OR) in the treatment of cerebral AVM. Hybrid operation can improve the ratio of total resection and efficacy of surgery of cerebral AVM, and reduce post-operative complications, medical costs and the repeated pain due to the repeated DSA examinations.
