PhotoAcoustic imaging is an imaging modality that uses laser light and ultrasound detectors to image tissues. Photo = Light. Acoustic = Sound. The imaging uses the photoacoustic effect principle. The photoacoustic effect is not new in terms of discovery as it was reported by none other than Alexander Graham Bell (yes! Rings a bell doesn’t it?) as early as 1880. But, the unavailability of proper detectors and instruments at his time was an obstacle to expanding research in this field.
Aim of Course
The course should provide knowledge about the physical properties of light and its impact and interaction with biological tissue. Course Content
Optical properties of biological tissue. Light transport in tissue. Therapeutic window. Light transport models. Measurement of tissue optical properties. Optical coherence tomography, multi-photon excitation, flourescens, etc.
