intravascular photoacoustic(English)
- another novel spectroscopic diagnostic technique for analyzing tissue composition. This modality emits short laser pulses into the vessel wall. Upon absorption of the laser energy, thermal expansion of the tissue generates photoacoustic waves that are received by an ultrasound transducer. It utilizes optical contrast provided by the differences in the absorption spectra of plaque components to image its composition
