Optic visualization of auricular blood vessels is considered using transillumination. Since the vessels and nerves course alongside one another, the locations of the nerves are disclosed. The visualization of the nerves is needed for a precise needle application by physician within the scope of electrical stimulation of auricular nerves; the stimulation being applied for pain relieve. Theoretical...
Pulmonary Edema (PE) is a life threatening disease that needs special attention in the area of research and clinical diagnosis. The computer based technique is rarely reported to quantify the intrathoracic fluid for the diagnosis purpose. In the present paper software has been developed to detect and diagnose pulmonary edema using LabVIEW. The developed software is based on physiological measurements...
This paper deals with the investigation of interesting analytical properties of the bidimensional fluctuations of the center of pressure (COP) during static posturographic tests (postural sway), namely their complex-valued and non-circular nature. These properties, ascertained by applying suitable statistical tests to experimental data, are prerequisite to pursue novel multidimensional representations...
Three criteria are suggested to help design a Clinical Decision Support System (CDSS) that would have a better chance of being successfully deployed in a clinical environment. These criteria have been successfully applied to a CDSS designed to estimate outcomes for neonatal intensive care unit (NICU) patients. The CDSS was deployed in a pilot study at the Children's Hospital of Eastern Ontario (CHEO)'s...
There have been many advances in the development and application of human computer interfaces during the past decade. We were motivated by these successful applications of human computer interfaces to design a low cost device which may also provide the user with a faster training time. In this paper we discuss the design and implementation and testing of the proposed device, and show that it can be...
This paper describes a CMOS Linear Voltage Regulator (LVR) of an implanted physiological signal system (biosensor) that is used to monitor blood pressure. This system is part of a Wireless Biomedical Sensor (WBS). The LVR topology is based on a classical structure of a Low Dropout Regulator (LDO). The energy is received from a RF link, thus operating as a passive RFID tag. The LVR was designed to...
The performance of three different Entity-Attribute-Value (EAV) storage formats for Clinical Data Repositories (CDRs) is compared with regards to querying millions of data points from clinical sources to assess the amount of storage space the data use, the speed with which the data can be obtained, and the complexity of the queries required to retrieve the data. Performance results are presented that...
The detection of central apneas using an unobtrusive pressure sensor array installed in the beds of smart homes could allow comfortable diagnosis of sleep disturbances. To improve central apnea detection, two methods of improving the results of apneas classified by a previously developed method are presented: moving average windowing and window elimination. The first improved classifier sensitivity,...
Heart rate variability (HRV) is an established indicator of cardiac health. Recent developments have shown the potential of nonlinear metrics for pattern classification of various heart conditions. Evidence indicates that the combination of multiple linear and nonlinear features leads to increased classification accuracy. In our paper, we demonstrate HRV classification using two dynamic nonlinear...
Social Networks have contributed the development of e-Health 2.0, which offers promising features of e-Health services any-time and anywhere. In this paper, we address the challenges of adding ubiquity in e-Health 2.0 applications and propose a ubiquity stack that is specialized in capturing temporal and spatial context of a user and can map necessary e-Health services and associated community of...
This paper presents the architecture, sensing and results of a context-aware smart home monitoring system based on pressure measurement sequences. It focuses on the analysis of transfers performed by the occupant in the bedroom and bathroom to assess if their behavior is within a normal range of motion. Pressure sensors are placed under the bed mattress and embedded in the grab bars of a toilet commode...
In this paper we propose a machine vision system for automatic segmentation of striatum in SPECT images. Moreover, in order to perform quantitative measurements on the dopaminergic neurotransmission system a 3D Striatum reconstruction method is proposed, which iteratively computes the position of every single vertex of an initial sphere according to the composition of external and internal forces...
In this paper we use both an embedded system and double Webcams to design an embedded monitor system for breath detection (EMSFBD) which monitors and records the patient's breath and sends the information to a specific server through the Internet. Our design uses image processing methods to monitor and record human breath fluctuation and to calculate the breath rate. If the breath rate is too low,...
Previous research using pressure sensors to monitor physiological signs, such as breathing and heart rate, has often been in controlled laboratory or institutional settings. We are interested in validating the use of such sensors in diverse home environments, where unobtrusiveness is achieved by embedding pressure sensors inside or below furniture.We have quantitatively examined outputs from sensors...
This paper presents a novel approach using principal component analysis (PCA) and adaptive neuro-fuzzy inference system (ANFIS) for estimation of blood pressure (BP) from oscillometric waveforms. The proposed method consists of three stages. In the first stage, the oscillation amplitudes (OAs) of the oscillometric waveforms are represented as a function of the cuff pressure. In the second stage, the...
In this paper, we present a capacitive sensor that measures the interfacial forces in prosthesis. The sensor's design, transfer function and performance metrics are tested and discussed. The sensor is uniquely able to measure both shear and normal stress simultaneously.
In this paper, we highlight the problem of measuring hand steadiness for the patients with Parkinson's Disease or those who need a rehabilitation program such as brain post-stroke patients. Using the accelerometer, we measure the accelerations against both the body motion and gravity, which is very useful for measuring postural orientations and body movement. In this paper, we present another method...
