ESE Seminar: "Detecting and Tracking of Freezing of Gait in Parkinson's Disease Patients Using Inertial Sensors" Seminar: "Detecting and Tracking of Freezing of Gait in Parkinson's Disease Patients Using Inertial Sensors"2017-05-02T05:00:00Z10 a.m.Green Hall, Room 0120<p>​Prateek Gundannavar Vijay, PhD Candidate, will present.<br/></p><p><strong>Abstract: </strong>Recent study suggests an increase in the incidence rates of parkinsonism and Parkinson's disease (PD) over the last 30 years. Early symptoms in PD are mostly movement related, including tremor, rigidity, slowness of movement, and postural instability. These asymmetrical and uncoordinated episodes of gait patterns are commonly referred to as freezing of gait (FOG). The episodic behavior of the FOG patterns is sudden, generally lasting for few seconds, tending to increase in frequency and duration as the disease progresses. Hence, understanding the FOG patterns can help in developing effective methods of diagnosis and treatment. Currently, clinicians use patient questionnaires with highly subjective scales to validate FOG. These scales do not accurately determine the onset and duration of FOG. Existing wearable sensor-based methods to detect FOG patterns: (i) require sophisticated gear; (ii) lack a signal model that incorporates the FOG patterns; (iii) use long window lengths to perform spectrum analysis; and (iv) demonstrate low sensitivity for the detection of the FOG patterns. To overcome these problems, we develop new methods to automatically detect the onset and duration of FOG in PD patients in real-time with high accuracy, using inertial sensors. We first build a physical model that describes the tremor motion during the FOG events. Then, we design a statistically-based generalized likelihood ratio test framework to develop a two-stage detector for determining the zero-velocity and tremor events in the gait motion. Thereafter, to filter falsely detected FOG events, we develop a point-process filter, that combines the output of the detectors with the information about the speed of the foot, provided by a foot-mounted inertial navigation system. We calculate the probability of FOG calculated by the point-process filter to determine the onset and duration of the FOG period. Finally, we validate the performance of the proposed system design using real data obtained from Parkinson’s disease patients who were asked to undergo a set of balance assessment tests that were likely to trigger FOG. We compare our FOG detection results with an existing method that uses the accelerometer data. Our results indicate that our method yields an improved performance in detecting FOG events and a three-fold decrease in the false alarm rate.<br/></p><p>Dissertation advisor: Dr. Arye Nehorai<br/></p>Shauna Dollison,

PhD Preliminary Research Examination: Nan Cui Preliminary Research Examination: Nan Cui2017-05-04T05:00:00Z1:30 p.m.Green Hall, Room 0120<p><strong></strong><strong>Abstract:</strong> Near-infrared (NIR) fluorescence image-guided surgery (IGS) is a medical technique that can provide critical structural and functional tissue or organ information to the surgeon in clinical settings to successfully detect and differentiate tumor tissue from surrounding healthy tissue. Current state of the art NIR imaging systems have two major shortcomings: First, they cannot capture NIR fluorescence information under surgical light illumination due to the high dynamic range requirements. Second, the combined NIR and color information is presented either on a monitor or videodisplay goggles. The surgeon’s natural vision is replaced with virtual information comprised by the color and NIR sensor. To address these shortcomings, I have successfully developed a multi-exposure image sensor with optical filters that capable of capturing both color and NIR image at the same time under surgical light source. However, the result reveals two major problems: 1) the dynamic range (DR) of the scene in the operating room (easily exceed 120 dB) cannot be detected and the signal-to-noise ratio (SNR) of low intensity object is lowed, caused by the read-out scheme of traditional voltage mode active pixel sensor (APS). 2) both the color and NIR fluorescence image are still displayed on a computer monitor. To address these shortcomings, I propose to investigate the realization of a bio-inspired, multi-spectral imager using time domain imaging. It will mimic the mechanism of butterfly’s eye and retina, producing uniformly high SNR and high DR. I will also investigate augmented reality display system that can present the NIR information without blocking the surgeon’s natural vision using Microsoft Hololens®, which allows the user to see the augmented image on the goggle transparent display component. One of the challenges is to co-register the NIR fluorescence augmented image with the actual target. I will develop an optical setup and algorithm to co-register the human natural vision, tumor and the augmented NIR fluorescence image. Finally, I will demonstrate the use of the bio-inspired CMOS multi-spectral imaging system and augmented reality display system in a small animal models and in clinical settings.<br/></p>Shantanu Chakrabartty
Women & Engineering Application Due & Engineering Application Due2017-05-12T05:00:00Z<p>All WashU Engineering women are invited to apply for membership in the Leadership Society for Women & Engineering. The Society creates a network for female engineers associated with Washington University. It pairs engineering students (juniors and seniors) with experienced female engineers (often alumnae) with similar professional interests to form "bear pairs." The Society meets twice a year: once in the fall for a networking dinner and once in the spring for a leadership conference. Costs are complimentary, courtesy of the Women & Engineering program. <br/><br/>Applications are due Friday, May 12, and students will be notified of acceptance during the summer.<br/></p><p><a href="/Events/_layouts/15/WopiFrame.aspx?sourcedoc=/Events/Documents/Leadership%20Society%20for%20W%20and%20E%20Student%20Application%20Form.docx&action=default">>> Download Application (Word)</a><br/></p>Emily Boyd,
