New papers published

Several papers were published in the last months. These are detailed here:

1) Steffen Resink and co-authors investigate for the first time acousto-optic imaging using a nanosecond pulsed laser. The method has the potential to overcome the speckle decorrelation problem in acousto-optics, and brings the possibility of in-vivo acousto-optic measurements closer. The authors describe their approach and results in: Towards acousto-optic tissue imaging with nanosecond laser pulses. Steffen Resink, Erwin Hondebrink, and Wiendelt Steenbergen Optics Express (2014) 22(3):3564-71

2) Michelle Heijblom and others describe for the first time the appearance of breast cysts in photoacoustics: Appearance of breast cysts in planar geometry photoacoustic mammography using 1064-nm excitation Michelle Heijblom, Daniele Piras, Erik Maartens, Erik J. J. Huisman, Frank M. van den Engh, Joost M. Klaase, Wiendelt Steenbergen, and Srirang Manohar Journal of Biomedical Optics (2013) 18(12):126009

3) Stefan Sandker and others investigate if laser speckle contrast analysis (LASCA) provides an objective determination of the reperfusion time. This is a technological version of the well-known Allen test which has implications in the implementation of coronary artery bypass graft surgery. The authors describe their work in: Laser speckle contrast analysis for quantifying the Allen test: A feasibility study Stefan Sandker, Erwin Hondebrink, Jan Grandjean, and Wiendelt Steenbergen Lasers in Surgery and Medicine (2013) 46(3):186-92

4) Jacob Staley and colleagues use photoacoustic signals from point sources to guide the formation of ultrasound wavefronts in acousto-optic imaging. This approach has potential to compensate for acoustic inhomogeneities allowing optimized ultrasound transmission to targeted locations. The approach and results are described in: Photoacoustic guided ultrasound wavefront shaping for targeted acousto-optic imaging.

5) Khalid Daoudi and colleagues investigate the feasibility of a method using simultaneous sound speed (SOS) imaging in photoacoustics, to pin-point the location of photothermal therapeutic agents and monitor the local temperature changes when the agents are excited with light. They describe their work in: Two-dimensional spatiotemporal monitoring of temperature in photothermal therapy using hybrid photoacoustic–ultrasound transmission tomography Khalid Daoudi, Peter van Es, Srirang Manohar, and Wiendelt Steenbergen Journal of Biomedical Optics (2013) Vol 18 (11), 116009
