A method for the calibration of wideband ultrasonic sensors for optoacoustics
(American Institute of Physics, 2021-06-16)
A method for calibration of ultrasonic sensors for optoacoustics that provides both frequency response and sensitivity is presented. In order to obtain the bandwidth and the frequency response of an uncalibrated sensor, a ...
Software-defined optoacoustic tomography
(Optical Society of America, 2020-01)
In this work we present what we believe is the first application of software-defined optoelectronics (SDO) for bidimensional optoacoustic tomography (OAT). The SDO concept refers to optoelectronic systems where the ...
Improvement of a system for 2-D optoacoustic imaging using a deconvolution filter
(Institute of Electrical and Electronics Engineers, 2018-06)
The detection system for optoacoustic tomography(OAT) usually employs broadband piezoelectric sensors basedon polymeric materials. Polyvinylidene fluoride (PVDF) andits copolymers are amongst the most popular ones. Within ...
A Comparative Study of Time Domain Compressed Sensing Techniques for Optoacoustic Imaging
(Institute of Electrical and Electronics Engineers, 2022-04)
Speeding up data acquisition and reducing the complexity of the detection system are among the central goals for advancing optoacoustic imaging. In this way, new reconstruction algorithms using the compressed sensing (CS) ...
Development of a breast-mimicking phantom for multispectral optoacoustic tomography
(Universidad EIAIngeniería BiomédicaEscuela de Ciencias de la VidaEnvigado (Antioquia, Colombia), 2022)
ABSTRACT: Multispectral Optoacoustic Tomography (MSOT) is an emerging imaging technology that generates high-resolution images by combining optical excitation and ultrasound detection. It has the ability to capture anatomical, ...
Parametric modeling of wideband piezoelectric polymer sensors: Design for optoacoustic applications
(American Institute of Physics, 2017-09)
In this work, we present a three-dimensional model for the design of wideband piezoelectric polymer sensors which includes the geometry and the properties of the transducer materials. The model uses FFT and numerical ...
Effect of Concentration on the Formation of Rose Bengal Triplet State on Microcrystalline Cellulose: A Combined Laser-Induced Optoacoustic Spectroscopy, Diffuse Reflectance Flash Photolysis, and Luminescence Study
(American Chemical Society, 2014-08)
Laser-induced optoacoustic spectroscopy (LIOAS), diffuse reflectance laser flash photolysis (DRLFP), and laser-induced luminescence (LIL) have been applied in conjunction to the determination of triplet state quantum yields ...
Dielectric antenna effects in integrating line piezoelectric sensors for optoacoustic imaging
(IOP Publishing, 2020-06)
This work studies the adverse effects, as regards noise, of immersing in water an integrating line piezoelectric detector devoted to optoacoustic imaging. We found that the sensor, in conjunction with the acoustic coupling ...
