Purpose:
To study the possibility of thermoacoustic imaging (TAI) toward hemorrhagic stroke detection.
Methods:
A single-transducer circular-scanning TAI system was used for data collection. An agar powder-based, tissue-mimicking phantom enclosed by a human skull was applied to simulate the brain for thermoacoustic imaging of hemorrhagic stroke.
Results:
Several phantom experiments mimicking hemorrhagic stroke detection were conducted, and the results showed that "hemorrhagic" targets as small as 0.9 mm in diameter could be detected.
Conclusions:
This study suggests that TAI has the potential to be used for noninvasive hemorrhagic stroke detection and identification of hemorrhagic from ischemic stroke.
