Sonification of optical coherence tomography data and images

Area of Science:

• Biomedical Engineering
• Medical Imaging
• Data Visualization

Background:

• Optical Coherence Tomography (OCT) generates data rapidly, challenging visual analysis.
• Multi-sensory input, like auditory feedback, can enhance data interpretation.
• Sonification offers a novel method for presenting complex data.

Purpose of the Study:

• To describe the auditory presentation of OCT data and images.
• To explore the utility of sonification for OCT data interpretation.
• To facilitate rapid analysis in time-sensitive surgical and diagnostic settings.

Main Methods:

• Developed techniques to translate OCT data and images into sound.
• Utilized spatial and spatial frequency properties of OCT data for sonification.
• Applied parameter-mapped sonification to human adipose and tumor tissues.

Main Results:

• Demonstrated the conversion of OCT data into non-speech audio signals.
• Presented results from sonification of human adipose and tumor tissues.
• Indicated potential usefulness of audio feedback for OCT image interpretation.

Conclusions:

• Sonification of OCT data provides a complementary sensory input.
• Auditory feedback can aid interpretation without constant visual monitoring.
• This technique may improve efficiency in surgical and diagnostic OCT applications.
