Article title

Imaging of myocardial infarction with
thermoacoustic tomography: An ex vivo study


Title variants

Languages of publication



In the present study, we evaluated the feasibility
of thermoacoustic tomography (TAT) for imaging of ex
vivo mouse hearts with myocardial infarction. A circular
scanning TAT system with an unfocused transducer was
used to recover the dielectric property distribution of normal
andmyocardial infarcted mouse heart tissues. The applicability
of this myocardial infarction imaging system
was validated using a model of myocardial infarction in
two Sprague-Dawley rats and verified through comparison
with magnetic resonance imaging (MRI). TAT results not
only indicated the location and ischemia and the extent of
myocardial ischemia (MI), but also showed good imaging
contrast between infarcted and normal myocardium without
the use of contrast agent. The experimental results suggest
that TAT may provide a unique opportunity to enable
real-time precision imaging to determine the site of injury
