Photoacoustic imaging endoscope

2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009
We currently present a design concept for a photoacoustic imaging endoscope as well as some preliminary experimental results. The device is based on the generation of acoustic waves in tissue by short laser pulses and the sensing of these waves with a thin, optical Fabry-Pérot etalon.

Photoacoustic computational ghost imaging

Optics Letters, 2022
Photoacoustic imaging with optical resolution usually requires a single-pixel raster scan. An alternative approach based on illumination with patterns obtained from a Hadamard matrix, measurement of the generated ultrasound wave with a single detector, followed by a reconstruction known from computational ghost imaging is demonstrated here.

Image reconstruction in intravascular photoacoustic imaging

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2011
Intravascular photoacoustic (IVPA) imaging is a technique for visualizing atherosclerotic plaques with differential composition. Unlike conventional photoacoustic tomography scanning, where the scanning device rotates around the subject, the scanning aperture in IVPA imaging is enclosed within the imaged object.

Intravascular ultrasound and photoacoustic imaging

2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008
There is a need for an imaging technique that can reliably identify and characterize the vulnerability of atherosclerotic plaques. Catheter-based intravascular ultrasound (IVUS) is one of the imaging tools of the clinical evaluation of atherosclerosis. However, histopathological information obtained with IVUS imaging is limited.
