Photoacoustic imaging of brachytherapy seeds using a channel-domain ultrasound array system
Tyler Harrison,Roger J. Zemp +1 more
TL;DR: In this paper, a photoacoustic system based on an L7-======4 array transducer and a real-time ultrasound array system capable of parallel channel data acquisition streamed to a multi-core computer via PCI-express was used for brachytherapy seed placement guidance and verification.
Proceedings ArticleDOI
Design of a High Frequency Array Based Photoacoustic Microscopy System for Micro-Vascular Imaging
TL;DR: A new high frequency array based photoacoustic microscopy system (PAM) using an Nd:YLF pumped tunable dye laser, a 30 MHz piezo composite linear array and a custom multi-channel receiver system is presented.
Proceedings ArticleDOI
Fundamental considerations for multiwavelength photoacoustic molecular imaging
TL;DR: In this article, the authors examined fundamental technical issues impacting capabilities of photoacoustic tomography for molecular imaging, and showed that errors in the estimated optical fluence are a source of bias in estimates of molecular agent concentration.
Journal ArticleDOI
Fiber-based photoacoustic remote sensing microscopy and spectral-domain optical coherence tomography with a dual-function 1050-nm interrogation source.
TL;DR: Adapting PARS to use the 1050-nm SD-OCT light source for interrogation enabled implementation of a fiber-based dual-modality system configuration, with image quality maintained, and will facilitate development of potential applications demanding handheld, catheter-based, or endoscopic form factors.
Proceedings ArticleDOI
Phase-function corrected diffusion model for diffuse reflectance of a pencil beam obliquely incident on a semi-infinite turbid medium
TL;DR: In this article, the phase-function corrected diffusion-theory is extended to the case of pencil beams obliquely incident on a semi-infinite turbid medium, and the model requires minimal computational resources and offers improved accuracy over more traditional diffusiontheory approximations models when validated against Monte Carlo simulations.
