Remote ultrasound detection with interferometer shows promise

Wednesday, November 29 | 2:20 p.m.-2:30 p.m. | W6-SSPH10-3 | Room E353C

The potential for remote ultrasound detection with an interferometer to produce high accuracy will be presented in this session.

In her talk, Kaitlyn Kim from the University of California, Irvine will discuss her team’s work describing how its non-contact ultrasound detection system based on a laser interferometer is superior to conventional methods in medical practice.

Current ultrasound detection methods use piezoelectric transducers or medical ultrasound probes. The Kim team, however, noted that user dependability can impact image quality and some patients may not be comfortable with ultrasonic gel.

Kim and colleagues wanted to present their remote laser interferometer method for ultrasound detection. This method would eliminate the need for direct contact of the transducer with the skin.

The researchers explained that producing the photoacoustic effect here involves radiant energy being absorbed to produce thermoelastic expansion. This results in the emitting of wideband ultrasound waves.

Using a phantom model, the team reported that its interferometer system could capture signals with no averaging for varied energy levels from a therapeutic laser.

“Even with the laser pulse energy at the lowest level, a distinct waveform can be observed,” the team wrote in its abstract.

With this, the researchers highlighted that their method could provide a grid map showing bodily regions.
