In sharper focus

Take a 40-year-old problem of ‘unfocused’ ultrasound images, add dedicated researchers at a centre for research-based innovation, and the result? Sharper, clearer images regardless of the patient’s anatomy – a vitally important improvement for diagnosing heart attacks and their severity.

The heat is on – transducer design

To inspect and test oil pipelines is crucial – both for health and safety, and for the environment. But the harsh conditions mean specialised equipment is imperative. When using ultrasound to perform non-destructive testing, this translates into a need for transducers that can withstand extremely high temperatures.

Ultrasound for improved crack detection

I have a created a modelling tool that can calculate ultrasonic sensitivity of cracks in pipelines, which is 8 times faster than commercial software. The model can simulate the behaviour and characteristics of waves within a pipe wall which are generated when an ultrasonic transmitter is radiating sound towards the pipe wall. These internal waves will be distorted somehow when encountering a crack, so knowing how these waves behave is vital in optimizing sensitivity in crack detection applications.

We built an AI tool to help avoid environmental disasters

Artificial intelligence helps us more and more with decision-making in fields such as medicine, transportation, and information retrieval. In collaboration with Equinor, Norway’s biggest oil and gas company, we have now added another field to the list: Interpreting integrity logs from oil and gas wells. Together, we built an AI-based assistant for Equinor’s log interpreters that they are now using in their daily work.
