Abstract
The following paper describes several transformations of ultrasonic
data into musical material for hemispheric loudspeaker
setup. This data comes from a medical prototype for the purpose
of early breast cancer detection via 3D multimodal imaging. The
data is acquired in a semi-ellipsoid mesh of thousands of ultrasonic
emitters and receivers surrounding the measurement object
with water as medium. A hemispheric loudspeaker array can reflect this aperture design and offers the possibility of projecting
this data in a direct fashion for auditory display. The ultrasounds
in the megahertz range are inaudible and need to be transformed
into the audible range. We here describe our investigations and
methods to transfer medical ultrasound data in an artistic context
and report on our insights using different sonification strategies to
gain audible, musical material.
