The Canadian Medical and Biological Engineering Society (CMBES) is Canada’s principal society for engineering in medicine and biology. It has as mission to advance and promote the theory and practice of engineering sciences and technology to medicine and biology, serving as a forum for information exchange between healthcare professionals, scientists, and the general public. Each year, CMBES organizes its national medical and biological engineering conference—CMBEC—thus providing a forum for international researchers to present their latest work and exchange ideas on the advancement of the theory and practice of medical device technology and biomedical engineering.
The use of technology in the practice of medicine has served to increase the standard of care for centuries. Recent innovations in medical technology are continuing to improve diagnostics, prognoses, and patient care. Many such innovations were presented at the CMBEC’39 conference held in Calgary, Alberta in May 2016. This Special Issue covers extended versions of works presented at the conference, as well as a handful of other related papers.
This Special Issue covers 15 papers, eight of which were presented at CMBEC and seven that were submitted to the journal and fit the theme of this special issue. Within the extended papers from CMBEC’39, the first from A. Phinyomark, G. Petri, E. Ibáñez-Marcelo, S. Osis, and R. Ferber, provides an overview of the current trends and future directions in the analysis of gait biomechanics, particularly in the era of big data analytics. Next, D. Sharifikia, G. Fradet, and H. Mohammadi describe their novel polymeric human aortic root made of hydrogel-based biomaterials for clinical and/or tissue engineering applications. K. Alam, M. Ghodsi, A. Al-Shabibi, and V. Silberschmidth, in turn, describe their investigation into the effects of bone drill point angle on the level of force and temperature in bone in the presence of ultrasonic vibrations imposed on the drill along the drilling direction. Such information is invaluable for efficient bone drilling in e.g., orthopedic procedures requiring screw insertions. J. Polisena, A. Sinclair, H. Hilfi, M. Bédard, A. Sedrakyan present a descriptive analysis of the continuous quality improvement data collected from a wireless smart infusion pump device implemented at one of the largest Canadian teaching hospitals. They assess dose error reduction compliance and identify which drugs were most prone to alerts. Next, M. Shekarforoush et al. present a general analytical method to determine three-dimensional linear and angular velocity of a joint and present a case study with the knee joint. Velocity analysis in joints is extremely useful in diagnosing and monitoring the progression of some diseases such as osteoarthritis. F. Deeba, S. Mohammed, F. Bui, and K. Wahid, in turn, present a saliency based unsupervised method for fast and accurate automatic localization and detection of angiectasia in conventional and capsule endoscopic images. Angiectasia is a common vascular lesion of the gastrointestinal tract. R. Booth and P. Goldsmith describe a low-cost wrist-mounted device that uses piezoelectric sensors to estimate finger gestures, thus bypassing the issues with lighting and movement seen in existing camera-based systems. Lastly, M. Rastgar-Jazi and F. Mohammadi propose an analytical solution for inverse heat conduction problem and by analyzing the thermo-grams obtained from infrared cameras, show that it is possible to assess chest tumor parameters such as depth and radius.
The remaining seven papers are not extended versions of papers presented at CMBEC’39, but, nonetheless, exhibit innovations in biomedical engineering, thus fit well within the scope of this special issue. These seven papers were chosen, as they exhibit innovations across a wide range of biomedical domains. For example, A. Jaiswal and H. Banka describe two new feature sets for automatic detection of seizures from electroencephalography (EEG) signals. M. Ranjbar, M. Mikaeili, and A. Banaraki, in turn, describe a modified spatiotemporal EEG filtering method for single-trial estimation of event related potential parameters such as peak latency and amplitude. Next, a diagnostic system based on variational mode decomposition to detect atrial and ventricular arrhythmia episodes from electrocardiogram signals is proposed by A. Chetan, R. Tripathy, and S. Dandapat. In turn, X. Guan, H. Du, Q. Li, and P.-H. Tsui propose a new combination of ultrasound imaging and Gaussian approximation for radiofrequency ablation monitoring. M. Parthasarthia and M. Ansari then describe a retrieval framework to extract similar 3D tumor volumes in magnetic resonance brain volumes in response to a query tumor volume, thus potentially improving clinical diagnostics. Next, M. Khandaker et al. propose the use of a biocompatible electrospun nanofibers matrix to improve the mechanical fixation and cytocompatibility of titanium and the bone. Lastly, Z. Cheng, H. Peng, R. Zhang, and G. Zhang provide an overview on existing and promising strategies for in vitro haematopoietic cells production for clinical use in e.g., cell therapy or substitution therapy.
