In a groundbreaking study published in AIP Advances on March 19, 2024, French researchers have unveiled the potential of ultrasound Technology in detecting surface thoracic vibrations during human vocalizations. This innovative approach, known as the “airborne ultrasound surface motion camera” (AUSMC), offers a non-invasive method to map these vibrations and provide valuable insights into respiratory Health.
The thorax, situated between the neck and abdomen, plays a crucial role in assessing an individual’s respiratory well-being. Traditionally, respiratory assessments have been subjective and reliant on the quality of the examination. While electronic stethoscopes have improved the detection of abnormalities during normal breathing, there has been a lack of technology to characterize surface vibrations produced during vocalizations.
The AUSMC technology, developed by the research team led by Mathieu Couade, allows for the observation of surface vibrations on the chest during vocalizations. By imaging these vibrations at high frame rates without the need for skin contact, the researchers were able to detect and map vocal fremitus in healthy volunteers.
According to Couade, the spatial distribution of vibrational energy was found to be asymmetric and frequency-dependent, showing differences between men and women. The AUSMC technology, coupled with artificial intelligence algorithms, holds promise for improving thorax examinations and diagnosing respiratory diseases more accurately.
Clinical trials utilizing AUSMC are underway to identify lung pathologies, paving the way for a new era of respiratory health assessment. The researchers anticipate that isolating vibration patterns through this technology could provide a better understanding of respiratory conditions and lead to enhanced diagnostic capabilities.
The study, titled “Airborne ultrasound for the contactless mapping of surface thoracic vibrations during human vocalizations: A pilot study,” is authored by a team of experts in the field and will be available in AIP Advances. This innovative research sets the stage for a transformative approach to respiratory health assessment, offering hope for improved diagnoses and treatments in the future.
