Keynote: Justifying Uberveillance- The Internet Of Things And The Flawed Sustainability Premise, Katina Michael
Professor Katina Michael
Imagine a world where everything was numbered. Not just homes with street addresses, or cars with number plates, or smart phones with telephone numbers, or email addresses with passwords, but absolutely everything you could see and touch and even that which you could not. Well, that world is here, right now. This vast expanse we call “Earth” is currently being quantified and photographed, inch by inch, by satellites, street cameras, drones and high altitude balloons. Longitude and latitude coordinates provide us with the precise degrees, minutes and seconds of the physical space, and unique time stamps tell us where a …

3d Thoracoscopic Ultrasound Volume Measurement Validation In An Ex Vivo And In Vivo Porcine Model Of Lung Tumours, V. Hornblower, E. Yu, A. Fenster, J. Battista, R. Malthaner

The purpose of this study was to validate the accuracy and reliability of volume measurements obtained using three-dimensional (3D) thoracoscopic ultrasound (US) imaging. Artificial "tumours" were created by injecting a liquid agar mixture into spherical moulds of known volume. Once solidified, the "tumours" were implanted into the lung tissue in both a porcine lung sample ex vivo and a surgical porcine model in vivo. 3D US images were created by mechanically rotating the thoracoscopic ultrasound probe about its long axis while the transducer was maintained in close contact with the tissue. Volume measurements were made by one observer using the …

Functional magnetic resonance imaging (fMRI) techniques have great potential for identifying which neural structures are involved in the control of goal-directed reaching movements. However, fMRI techniques alone are not capable of probing the neural mechanisms involved in acquisition of novel motor behaviors because such studies require that the moving limb be perturbed in a controlled fashion. We outline a plan to design and develop a non-metallic, pneumatically actuated tool that, along with systems identification techniques and functional magnetic resonance imaging (fMRI), will characterize and quantify how the human central nervous system uses sensory information during practice-based motor learning.

We developed a real-time controller for a 2 degree-of-freedom robotic system using xPC Target. This system was used to investigate how different methods of performance error feedback can lead to faster and more complete motor learning in individuals asked to compensate for a novel visuo-motor transformation (a 30 degree rotation). Four groups of normal human subjects were asked to reach with their unseen arm to visual targets surrounding a central starting location. A cursor tracking hand motion was provided during each reach. For one group of subjects, deviations from the "ideal" compensatory hand movement (i.e. trajectory errors) were amplified with …
A Low-Field P-31 Nmr Spectrometer To Measure Bone Mineral In The Human Wrist, Joseph Battocletti, Thomas Meyers, Robert Scheidt
A Low-Field P-31 Nmr Spectrometer To Measure Bone Mineral In The Human Wrist, Joseph Battocletti, Thomas Meyers, Robert Scheidt
Robert Scheidt
Nuclear magnetic resonance phosphorus spectroscopy (NMRS) is a method of measuring the mineral content of bone as a diagnostic tool for osteoporosis. A description is given of the design and construction of a low-field spectrometer for the human wrist. It uses a small-size permanent magnet of neodymium-iron-boron. The questions of whether a low-field spectrometer is sensitive enough to measure the phosphorus mineral content of bone and to what extent the phosphorus in soft tissue affects the measurement of bone mass are discussed
The Future Prospects Of Embedded Microchips In Humans As Unique Identifiers: The Risks Versus The Rewards, Katina Michael, M G. Michael
The Future Prospects Of Embedded Microchips In Humans As Unique Identifiers: The Risks Versus The Rewards, Katina Michael, M G. Michael
Professor Katina Michael
Microchip implants for humans are not new. Placing heart pacemakers in humans for prosthesis is now considered a straightforward procedure. In more recent times we have begun to use brain pacemakers for therapeutic purposes to combat illnesses such as epilepsy, Parkinson's disease, and severe depression. Microchips are even being placed inside prosthetic knees and hips during restorative procedures to help in the gathering of post-operative analytics that can aid rehabilitation further. While medical innovations that utilize microchips abound, over the last decade we have begun to see the potential use of microchip implants for non-medical devices in humans, namely for …

A Fully Automated Non-External Marker 4d-Ct Sorting Algorithm Using A Serial Cine Scanning Protocol, Greg Carnes, Stewart Gaede, Edward Yu, Jake Van Dyk, Jerry Battista, Ting-Yim Lee
A Fully Automated Non-External Marker 4d-Ct Sorting Algorithm Using A Serial Cine Scanning Protocol, Greg Carnes, Stewart Gaede, Edward Yu, Jake Van Dyk, Jerry Battista, Ting-Yim Lee

Current 4D-CT methods require external marker data to retrospectively sort image data and generate CT volumes. In this work we develop an automated 4D-CT sorting algorithm that performs without the aid of data collected from an external respiratory surrogate. The sorting algorithm requires an overlapping cine scan protocol. The overlapping protocol provides a spatial link between couch positions. Beginning with a starting scan position, images from the adjacent scan position (which spatial match the starting scan position) are selected by maximizing the normalized cross correlation (NCC) of the images at the overlapping slice position. The process was continued by 'daisy …

The purpose of this paper is to describe a non-invasive method to monitor the motion of internal organs affected by respiration without using external markers or spirometry, to test the correlation with external markers, and to calculate any time shift between the datasets. Ten lung cancer patients were CT scanned with a GE LightSpeed Plus 4-Slice CT scanner operating in a ciné mode. We retrospectively reconstructed the raw CT data to obtain consecutive 0.5 s reconstructions at 0.1 s intervals to increase image sampling. We defined regions of interest containing tissue interfaces, including tumour/lung interfaces that move due to breathing …

Lung cancer treatment is one of the most challenging fields in radiotherapy. The aim of the present study was to investigate what role helical tomotherapy (HT), a novel approach to the delivery of highly conformal dose distributions using intensity-modulated radiation fan beams, can play in difficult cases with large target volumes typical for many of these patients. Tomotherapy plans were developed for 15 patients with stage III inoperable non-small-cell lung cancer. While not necessarily clinically indicated, elective nodal irradiation was included for all cases to create the most challenging scenarios with large target volumes. A 2 cm margin was used …

Computed Tomography To Assess Pulmonary Injury Associated With Concurrent Chemo-Radiotherapy For Inoperable Non-Small Cell Lung Cancer, Galit Aviram, Edward Yu, Patricia Tai, Michael Lefcoe
Edward Yu
OBJECTIVE: To characterize serial computed tomography (CT) findings of pulmonary injury after a uniform regimen of concurrent chemo-radiotherapy in inoperable non-small cell lung cancer, and to compare the radiation-induced lung toxicity with other concurrent chemo-radiation regimens. METHODS: Twenty-four patients with advanced non-small cell lung cancer received 2 induction cycles of cisplatin and vinblastine, followed by 2 further cycles of cisplatin and vinblastine, concurrent with 60 Gy radiation at 2 Gy per fraction. Radiation-induced lung injury in the acute and chronic phases was assessed by serial CT scans and compared with preradiation baseline scans. Acute radiation pneumonitis was evaluated using the …

In order to re-assess the potential contribution of infrared (IR) imaging as a first-line component of a multi-imaging strategy using currently available technology, we first review the history of its introduction and clinical application, including the results of the Breast Cancer Detection Demonstration Projects (BCDDP). We then discuss experiments with a new high-resolution, computerized IR station and software program acquired by the Ville Marie Breast Center to assess IR imaging's ability to complement clinical examination and mammography in the early detection of breast cancer. Our goal is to show that high-resolution IR imaging provides additional safe, practical, and objective information …
