Opto acoustic tomography
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 (i.e. MHz) ultrasonic emission. The generated ultrasonic waves are d… WebJan 1, 2014 · The spiral volumetric optoacoustic tomography technique is introduced that provides spectrally enriched high-resolution contrast across multiple spatiotemporal scales and adds to the multifarious advantages provided by the opto-acoustic technology for structural, functional and molecular imaging.
