We have made a comparison of various detection strategies for detection of acoustically modulated light in a scattering medium. Furthermore we have investigated the possibility to determine the local absorbance in a model system mimicking a blood vessel in tissue.
Performance studies of a clinical prototype for detecting tumors in the breast based on the photoacoustic effect are presented in
terms of sensitivity, frequency response and resolution. Some imaging results on well characterized breast tissue phantoms with embedded tumor simulating inserts are also shown.
