Monitoring and Analysis of Respiratory Patterns Using Microwave Doppler Radar

Y. S. Lee, P. N. Pathirana, C. L. Steinfort, T. Caelli

Non-contact detection characteristic of Doppler radar provides an unobtrusive means of respiration detection and monitoring. This avoids additional preparations such as physical sensor attachment or special clothing which can be useful for certain healthcare applications. Furthermore, robustness of Doppler radar against environmental factors such as light, ambient temperature, interference from other signals…

Automatic Detection and Classification of Unsafe Events during Power Wheelchair Use

J. Pineau, A. Moghaddam, H. K. Yuen, P. Archambault, F. Routhier, F. Michaud, P. Boissy

Using a powered wheelchair (PW) is a complex task requiring advanced perceptual and motor control skills. PW incidents and accidents are not uncommon and their consequences can be serious. The objective of our research is to develop technological tools that can be used to characterize a wheelchair user’s driving behavior under various settings…

The Effect of Light Conditions on Photoplethysmographic Image Acquisition Using a Commercial Camera

H. Liu, Y. Wang, L. Wang

Cameras embedded in consumer devices have previously been used as physiological information sensors. The waveform of the PPGi signals may be significantly affected by the light spectra and intensity. The purpose of this paper is to evaluate the performance of PPGi waveform acquisition in the red, green, and blue channels using a commercial camera in different light conditions…

A Bayesian Algorithm for Anxiety Index Prediction Based on Cerebral Blood Oxygenation in the Prefrontal Cortex Measured by Near Infrared Spectroscopy

Y. Fukuda, Y. Ida, T. Matsumoto, N. Takemura, K. Sakatani

Stress-induced psychological and somatic diseases are virtually endemic nowadays. Written self-report anxiety measures are available; however, these indices tend to be time consuming to acquire. For medical patients, completing written reports can be burdensome if they are weak, in pain, or in acute anxiety states. Consequently, simple and fast non-invasive methods for assessing stress response from neurophysiological data…

Current and Future Challenges in Point-of-Care Technologies: A Paradigm-Shift in Affordable Global Healthcare with Personalized and Preventive Medicine

A.P. Dhawan, W.J. Heetderks, M. Pavel, S. Acharya, M. Akay, A. Mairal, B. Wheeler, C.C. Dacso, T. Sunder, N. Lovell, M. Gerber, M. Shah, S.G. Senthilvel, M.D. Wang, B. Bhargava

Pre-Publication POCHT 2013 White Paper
This paper summarizes the panel discussion at the IEEE Engineering in Medicine and Biology Point of Care Healthcare Technology Conference (POCHT 2013) held in Bangalore India from Jan 16-18, 2013. Modern medicine has witnessed interdisciplinary technology innovations in healthcare with a continuous growth in life expectancy across the globe. However, there is also a growing global concern on the affordability of rapidly rising healthcare costs…

Pre to Intraoperative Data Fusion Framework for Multimodal Characterization of Myocardial Scar Tissue

A. R. Porras, G. Piella, A. Berruezo, J. Fernandez-Armenta, A. F. Frangi

This paper presents a framework to analyze and combine information from delayed enhancement magnetic resonance imaging (DE-MRI) and electro-anatomical mapping data. This information is used to perform electrical, mechanical and image-based characterization of the myocardium. The proposed framework has the potential to guide and monitor delivery of radiofrequency ablation of ventricular tachycardia…

Controlling knee swing initiation and ankle plantarflexion with an active prosthesis on level and inclined surfaces at variable walking speeds

N. P. Fey, A. M. Simon, A. J. Young, L. J. Hargrove

Improving lower-limb prostheses is important to enhance the mobility of amputees. The purpose of this study was to introduce an impedance-based control strategy (consisting of four novel algorithms) for an active knee and ankle prosthesis and test its generalizability across multiple walking speeds, walking surfaces and users…

Experimental Procedure for Determination of the Dielectric Properties of Biological Samples in the 2-50 GHz Range

E. Odelstad, S. Raman, A. Rydberg, R. Augustine

The objective of this paper was to test and evaluate an experimental procedure for providing data on the complex permittivity of different cell lines in the 2–50-GHz range at room temperature, for the purpose of future dosimetric studies. The complex permittivity measurements were performed on cells suspended in culture medium using an open-ended coaxial probe…

Scope Statement

We focus on innovative solutions to healthcare needs from biomedical engineering, clinical engineering, and medical communities that bridge the engineering and clinical worlds. JTEHM's unique scope is original work at the intersection of engineering and clinical translation.

The journal’s focus is interdisciplinary collaborations among researchers, healthcare providers, and industry. We publish results and best practices from these translational efforts and serve as a community hub for researchers, clinicians, and developers who are addressing challenges in technology development, commercialization, and deployment for better global healthcare. Our ultimate goal is to improve the practice of engineering in translational medicine and to serve as a focal point for the nascent community. Our interactive content includes video, lively commentary, blogs, and other features to engage our clinical and engineering communities.
