Ryan Colquhoun does a Nuffield project at CavLab

Ryan Colquhoun (pictured), of James Hamilton Academy, Kilmarnock, gave up most of his summer holiday to work in CavLab for 6 weeks, on a Nuffield project.

Ryan was helping us out with the new Acoustic Cluster Therapy project (more details on that, soon).

Oh, and did I mention, he totally aced his Advanced Highers!?

Thanks and good luck Ryan (not that we think you’ll need much that!)

Jae ‘shocks’ the passive acoustic mapping community at IEEE IUS in Tours, France, 2016

jae_ieee-ius_2016Oh la la! Cavlab has been on tour …in Tours, France! Jae presented on the role of periodic shock waves in passive acoustic mapping of cavitation – a spatio-temporal monitoring technique. Our Jae got quite a lot of attention after this talk….

Krsitoffer presented on shadowgraphic imaging of focused ultrasound as a characterisation technique. He missed out on the student paper prize, but put in a great effort. Next time, mate, it’s got your name on it!

Allez CavLab! Viva L’espana (insider joke)

 

Keith Johnston bags his PhD

CavLab is delighted to announce that Keith passed his PhD viva examination (with very minor corrections), at the end of August, 2016.

Keith’s taking a lectureship position in Mechanical Engineering, at the University of Dundee, fresh out of his PhD labours.

It was a long and twisty road, Keith – but when your external examiner asks if you will make him a couple of your detection devices, you know you’ve nailed it!

Nice one, and all the best for the future.

Elizabeth Casey does her work experience at CavLab

Elizabeth Casey, form St George’s school, Edinburgh did her work experience at CavLab, this summer.

Currently, Elizabeth is thinking of doing theoretical physics/astrophysics at uni – this was our opportunity to convince her that experiments are also worthy…

…but we were just glad not to put her right off research. In fact, we think she’s made of the right stuff. Good luck with whatever you decide to do, Elizabeth, and when the time comes, remember to check in for PhD project positions!

Best wishes

CavLab

CavLab takes delivery of its high-speed camera

Finally! It’s here!

Our Shimadzu HPV-X, capable of imaging at up to 10 million frames per second.

CavLab are always interested in developing new collaborations, and exploring new opportunities. If you would like to discuss the possibility of accessing this facility, let us know.

 

Here’s some data we took, recently, with our new favourite toy.

We don’t think it really means anything (otherwise we’d have tried to publish!), but we think it looks cool.

For what it’s worth, this is a ‘big’ laser bubble, which is about 0.5 mm at its maximum radius, in the focus of a 3.3 MHz focused ultrasound field. The movie was taken  at 5 million frames per second. Oh, and there’s a sewing needle-tip at the top of the field of view, which we use for alignment purposes.

You can see all sorts shock waves, and their relections, superimposed over the focused ultrasound in the background. It looks like the field is causing the bubble to wobble, as it contracts towards collapse.

Cool, huh?

CavLab rapid control feedback loop nominated for NI Global Engineering Impact Award

A case study on our prototype autonomous and ultra-rapid cavitation control feedback loop (joint with collaborators at Diagnostic Sonar Ltd) made it all the way to finalist at the National Instrument Global Engineering Impact Awards (in the Advanced Research category), at Austin Texas, 2015.

We didn’t quite win – a very worthy arterial stiffness evaluation technology pipped us to the post, but we got a nice certificate out of it!
