Journal ArticleDOI
Multispectral photoacoustic coded excitation imaging using unipolar orthogonal Golay codes
Martin P. Mienkina,Claus-Stefan Friedrich,Nils C. Gerhardt,Martin F. Beckmann,Martin F. Schiffner,Martin R. Hofmann,Georg Schmitz +6 more
TL;DR: The feasibility of the MS-PACE method is demonstrated by successfully imaging a phantom composed of two dyes using unipolar orthogonal Golay codes as excitation sequence for two high power laser diodes operating at two different wavelengths.
Journal ArticleDOI
Size-dependent multispectral photoacoustic response of solid and hollow gold nanoparticles
Benjamin S. Gutrath,Martin F. Beckmann,Anne Buchkremer,Thomas Eckert,Jan Timper,Annika Leifert,Walter Richtering,Georg Schmitz,Ulrich Simon +8 more
TL;DR: The molar PA intensity of 1.0 nm AuNPs was comparable to the commonly used organic dye methylene blue, and rapidly increased with the lateral size of AuN Ps, according to the diode laser set-up.
Journal ArticleDOI
Photoacoustic clutter reduction by inversion of a linear scatter model using plane wave ultrasound measurements.
TL;DR: This study seeks to exploit the acoustic tissue information gained by plane wave ultrasound measurements with a linear array in order to correct for reflections in the photoacoustic image by deriving a theory for clutter waves in k-space and a matching inversion approach.
Journal ArticleDOI
Optimized SNR simultaneous multispectral photoacoustic imaging with laser diodes.
TL;DR: A novel signal processing concept is introduced, which optimizes the SNR in the reconstructions of single wavelength data from combined acquisitions while simultaneously permitting to obtain a higher SNR fused image from the same data.
Proceedings ArticleDOI
Multispectral photoacoustic coded excitation using pseudorandom codes
Martin F. Beckmann,Claus-Stefan Friedrich,Martin P. Mienkina,Nils C. Gerhardt,Martin R. Hofmann,Georg Schmitz +5 more
TL;DR: In this article, pseudorandom shift register sequences (m-sequences) are introduced and analyzed for multispectral photo-acoustic coded excitation (MSPACE), and their gain in SNR exceeds that of orthogonal Golay codes for finite code lengths.
