The Leicester study has discovered that techniques used in radar systems can be modified and have the potential to improve early diagnosis and effective monitoring of stroke victims.
Research by Joanne Cowe in the University’s Medical Physics group led to the breakthrough which offers huge potential to deliver benefits to patients.
Joanne said: “Stroke is the third most common cause of death and the most common cause of adult disability in the UK and is estimated to cost the NHS over £2.3 billion per year. One quarter of strokes are due to emboli (blood clots or other foreign bodies) blocking small blood vessels in the brain. Emboli can originate from a number of sources such as the heart or from plaques in arteries in the head or neck due to vascular disease.
“Doppler ultrasound can be used for the detection of emboli in the cerebral circulation and can also be used to monitor the blood flow through vessels to assess if there are any problems such as blockages. Therefore, research into the detection of emboli and vascular disease, using ultrasound, has the potential to reduce stroke death and disability rates, and to generate large financial savings.”
Joanne graduated with a Masters in Electrical and Electronic Engineering before going on to work as a military systems engineer. She then went on to undertake a PhD as part of the University of Leicester’s Medical Physics group. In her PhD she investigated how radar techniques could improve the operation of medical ultrasound devices. In particular she looked at how these technologies could be used to detect and monitor the blood clots or other foreign bodies travelling through blood vessels in the brain which can lead to strokes.
Joanne will be presenting the findings of her Ph.D. research at a doctoral inaugural lecture on Wednesday 6th February. In this lecture she will explain how she investigated new methods of processing the ultrasound signal so as to obtain additional information. In particular she will be describing how techniques used in radar systems can be modified and utilised in a Doppler ultrasound system to improve the resolution, thereby providing more detailed information about the depths at which movement is occurring. This has the potential to aid in the early diagnosis and also in the monitoring of progression of vascular disease.
The second doctoral inaugural lecture will take place on Wednesday 6th February at 5.30pm in Ken Edwards Lecture Theatre 3. In addition to Joanne Cowe it will also feature Carolyn Tarrant (School of Psychology) talking about her research on “Trust Me I’m A Doctor”.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
