Photographic acoustic
WebThe principal of the photoacoustic effect is simple. Nanosecond pulsed laser light is used to illuminate the tissue. Chromophores such as hemoglobin and red blood cells absorb the light which causes local heating and thermoelastic expansion. Pressure or sound waves are emitted and detected by our ultra high frequency transducers. Photoacoustic imaging or optoacoustic imaging is a biomedical imaging modality based on the photoacoustic effect. Non-ionizing laser pulses are delivered into biological tissues and part of the energy will be absorbed and converted into heat, leading to transient thermoelastic expansion and thus wideband … See more The optical absorption in biological tissues can be due to endogenous molecules such as hemoglobin or melanin, or exogenously delivered contrast agents. As an example, Fig. 2 shows the optical absorption spectra of See more General equation Given the heating function $${\displaystyle H({\vec {r}},t)}$$, the generation and propagation of photoacoustic wave pressure $${\displaystyle p({\vec {r}},t)}$$ in an acoustically homogeneous inviscid medium is governed … See more Photoacoustic imaging has seen recent advances through the integration of deep learning principles and compressed sensing.
