"Future Directions in Cardiac Interventions: what imaging methods are in use today and what tools will we need in the future?"

Conferral summary

We har utviklet løsninger for autostereoskopisk visualisering og forbedret fremstilling av katetere under ultralydveiledete inngrep i hjertet. Det ble vist at dette løsningene gav forbedret treffsikkerhet for komplekse oppgaver knyttet til ultralydveiledet behandling. I tillegg ble det utviklet en metode for automatisk justering av fargedoppler, som førte til forbedret nøyaktighet og reproduserbarhet ved gradering av klaffelekasjer. Disse nye methodene har potensialet til å forbedre pasientsikkerhet og redusere tiden på operasjonsstuen for ultralydveiledete inngrep.

Main research findings

Cardiovascular disease is one of the leading causes of death globally and cardiac ultrasound, echocardiography, is an essential tool used for assessing the condition of the heart noninvasively.


The primary focus of our research has been to improve 3D echocardiography for interventional purposes. We present a novel method for real-time catheter localization and visualization that makes it easier to distinguish these instruments from the surrounding tissue. In addition, we introduce a real-time system for image guidance that renders an acquired sequence of images on the glasses-free 3D display to increase the depth perception of ultrasound data. Furthermore, since quantification is an important part of interventional echocardiography, we present a method for optimizing some of the ultrasound scanner’s parameters that allows for a more accurate assessment of the leaking heart valve condition.


Improved visualization of ultrasound data combined with more accurate measurements can increase the confidence of surgeons and ultrasound operators. In interventional setting, all these improvements have the potential to improve patient safety and decrease the duration time of these procedures.
