Dynamic Cardiovascular Imaging for Rapid Patient Treatment Planning


The clinical gold standard for assessing the functional significance of a coronary artery stenosis is the invasive fractional flow reserve (FFR) technique, in which a specialized catheter is advanced to the culprit artery with aids of fluoroscopy to measure the flow pressure gradient across a plaque during maximal hyperemia. Recently, non-invasive assessment of FFR using CT coronary angiography (CCTA) images has emerged as a promising avenue for evaluation of higher risk patients requiring anatomical and functional assessment for coronary artery disease (CAD). However, at the present time, FFR evaluation by CCTA requires extensive post-processing and calculation (often greater than 24 hours) and, therefore, is not presently suitable for evaluation of patients in the ED setting. A recent systematic review has revealed that the accuracy of FFR-CT measurement decreases as the degree of stenosis increases when compared to the gold standard catheter-based FFR measurement (Cook et al. (2017) Diagnostic accuracy of computed tomography-derived fractional flow reserve. A systematic review. JAMA Cardiol; 2(7):803-810. Accordingly, there is a continuing need for alternative methods and systems for imaging based assessment of a blood vessel in a subject.

Technology Overview

A novel time-resolved dynamic angiographic computed tomography (TRD-ACT) method has been developed to facilitate the assessment of the hemodynamics in epicardial coronary arteries. Coronary blood flow, fractional flow reserve (FFR), flow friction and turbulence indexes, and shear stress in each coronary artery can be assessed directly from the dynamic contrast-enhanced heart images acquired from myocardial perfusion imaging. FFR measurement can be used to evaluate whether a stenosis (luminal narrowing) is functionally significant to inform decision-making on interventional reperfusion treatment. Assessment of shear stress across an atherosclerotic plaque can provide useful insight on the risk of plaque rupture, which may allow earlier prevention of thrombosis. This technique can potentially be generalized for studying diseases in other organs such as assessing the hemodynamics of the carotid arteries in stroke patients.


  • Facilitates the clinical use in both outpatients and emergency departments as it is computationally less intensive (about 1-2 minutes per patient study, minimal assumption for the calculation, based largely on real dynamic data measured) than FFR-CT (usually takes more than 24 hours per patient study, estimates drop across a coronary artery plaque based on extensive assumptions on many physiologic parameters)
  • Capable of simultaneously assess the large (epicardial) and small (microvascular) coronary arteries
  • Hemodynamic parameters such as shear stress across a plaque can be estimate, which may lead to a more reliable prediction of the risk of plaque rupture

Antibacterial Phage Hydrogels


Bacteriophages (also known as phages) are viruses that specifically fight bacteria in nature, without affecting non-bacteria cells. Bacteriophages have been used for over 100 years in clinics around the world to treat bacterial infections. With the rise of superbugs, phages have garnered more attention as a targeted approach to fight antimicrobial resistant bacteria.
Phages have been developed as structural material for developing coatings and gels, but the focus has so far never been on their antimicrobial property, but rather their identity as protein nanoparticles. Therefore, no effort was made to preserve phage antimicrobial activity when it was used as structural material.

Fortunately, McMaster researchers have created hierarchically structured hydrogels composed entirely of self-organized phage. These phage hydrogels retain the innate antimicrobial activity of free phage and in addition, they can return to its original state after being cut or sheared with minimal scarring (self-healing). These bioactive hydrogels also biodegrade and emit fluorescence, allowing non-destructive imaging. These simple and versatile hydrogel compositions can be utilized within a plethora of medical and environmental applications.


  • Medical applications:
    • Antibacterial wound dressings
    • Antibacterial coatings on healthcare surfaces
    • Antibacterial sutures for surgical wounds
    • Antibacterial injectable hydrogel for grafts and implants


  • Targeted antimicrobial activity (kills only specific bacteria)
  • The hydrogels biodegrade in the body
  • Bioactivity includes antibacterial activity, self-healing, and autofluorescence
  • Soft and hydrated gel properties are similar to human tissue
  • Can naturally target and kill specific bacteria strains
  • Can be genetically engineered to target specific tissues and/or cells (e.g. tumours), materials (e.g. plastics, metals, minerals) or small molecules (e.g. ions)



The self-healing and autofluorescent hydrogel made entirely of bacteriophage can be used for a variety of medical and environmental applications.

Kinetic Energy Dissipation System


Technologies designed to absorb and dissipate the kinetic energy of impact play a significant role in preventing critical injuries and death. They have a broad range of applications, including reducing the force of impact in military explosions, vehicle accidents, and fall arrest systems. Conventional destructive dynamic forces are dissipated by energy-absorbing devices such as springs, rubber buffers, hydraulic fluids, or sacrificial structural members that experience deformation. However, many of these systems/structures suffer a significant disadvantage of not dissipating energy in a controlled and desired fashion, causing decreased system performance. The proposed technology overcomes this by providing a stable, and controllable deformation mode, which occurs at a designated force, resulting in efficient, uniform, and precise energy absorption capabilities. Additionally, the technology allows for passive adaptive energy dissipation characteristics, which is beyond the current state-of-the-art.

Technology Overview

This kinetic energy dissipation system consists of a cylindrical sacrificial tube (aluminum or other materials for the tube can be used) and a cutting member shaped like a steel wheel with four or more spoke-like blades designed appropriately for the specific energy dissipation requirement. Upon impact, the device cuts through the sacrificial deformation tube (Figure 1), in a steady process allowing for controllable metal deformation. This deformation mode is preferred compared to other systems, which may crumble or distort unevenly. The result is an almost ideal elastic/perfectly plastic system response, which is desired for energy dissipation. The system has been well proven and tested under quasi-static, low-speed dynamic and blast load conditions. Numerical and analytical models have been developed to aid in engineering the kinetic energy dissipation system for a specific application.


  • Simple design that is easily customized, and has a low manufacturing cost
  • Aluminum alloy sacrificial tube is lighter than alternative steel solutions and does not corrode
  • System can have a programmable load and stable deformation behaviour that can now outperform the current state-of-the-art
  • Energy absorption does not create high temperature, severed or flying pieces of materials
  • Can perform in both tension and compression loading conditions

Advanced Perovskite Films and Crystals for Stable Energy Harvesting Solar Panels


Metal halide perovskites possess unique features that make them desirable for solar cell and other electronic device applications. The most commonly studied perovskite absorber is methylammonium lead trihalide family However the instability of organic lead halide perovskites, such as methylammonium lead tri-iodide (MAPbI3), under ambient conditions is a challenge, as it leads to degradation in electronic device performance and has thus limited their long term application.

Technology Overview

Waterloo researchers have developed a perovskite-polymer composite that consists of a cross-linked polymer network integrated with a perovskite film By way of one example, a precursor mixture of PbI2 (acting as a Lewis acid) with polystyrene (PS) enabled in-situ PS crosslinking arising in a novel perovskite-polymer composite without any encapsulating layer and with a stable structure in ambient conditions after more than 1000 h of continuous 1.0 sun (AM 1.5G) illumination in air (relative humidity of 40–50%) at 45 °C, while also showing a slightly improved device performance. The stability is the result of the direct specific interaction between the polymer and the perovskite that reduces ion migration, charge recombination, trap-state density and dark currents and at the same time leads to improve mobility and carrier life time. The interaction between the polymer and PbI2, also improves the crystallization kinetics leading to larger grain size in the perovskite films. The cumulative effect of these improvements makes the reported polymer-perovskite hybrids well suited for long term device applications.


The production method improves the perovskite solar cell stability under normal operating conditions and without requiring any additional encapsulation for significantly greater time compared to other reported methods. This method not only maintains but also improves the efficiency by 1.5-2% for solar cells in a simple one step method using low cost polymer additive. This improved efficiency is significant for photovoltaic applications.


Cost-effective solar cells with high efficiency and simple fabrication, optoelectronic devices based on specific effects in perovskites such as super-capacitors, piezoelectric, ferroelectrics, sensors, energy harvesting devices, catalysis.
