Artifacts in Photoacoustic Imaging: Origins and Mitigations
Max T. Rietberg, Janek Gröhl, Thomas R. Else +3
Photoacoustic imaging (PAI) is rapidly moving from the laboratory to the clinic, increasing the need to understand confounders which might adversely affect patient care. Over the p…
Super Phantoms: advanced models for testing medical imaging technologies
Srirang Manohar, Ioannis Sechopoulos, Mark A. Anastasio +3
Phantoms are test objects used for initial testing and optimization of medical imaging techniques, but these rarely capture the complex properties of the tissue. Here we introduce…
Fully three-dimensional sound speed-corrected multi-wavelength photoacoustic breast tomography
M. Dantuma, F. Lucka, S. C. Kruitwagen +21
Photoacoustic tomography is a contrast agent-free imaging technique capable of visualizing blood vessels and tumor-associated vascularization in breast tissue. While sophisticated…
An anthropomorphic thyroid phantom for ultrasound-guided radiofrequency ablation of nodules
Tim Boers, Wyger Brink, Leonardo Bianchi +6
Background: Needle-based procedures such as fine needle aspiration (FNA) and thermal ablation, are often applied for thyroid nodule diagnosis and therapeutic purposes, respectively…
A Partially Learned Algorithm for Joint Photoacoustic Reconstruction and Segmentation
Yoeri E. Boink, Srirang Manohar, Christoph Brune
In an inhomogeneously illuminated photoacoustic image, important information like vascular geometry is not readily available when only the initial pressure is reconstructed. To obt…
A Framework for Directional and Higher-Order Reconstruction in Photoacoustic Tomography
Yoeri E. Boink, Marinus J. Lagerwerf, Wiendelt Steenbergen +3
Photoacoustic tomography is a hybrid imaging technique that combines high optical tissue contrast with high ultrasound resolution. Direct reconstruction methods such as filtered ba…
A method for delineation of bone surfaces in photoacoustic computed tomography of the finger
Samir Biswas, Peter van Es, Wiendelt Steenbergen +1
Photoacoustic imaging of interphalangeal peripheral joints is of interest in the context of using the synovial membrane as a surrogate marker of rheumatoid arthritis. Previous work…
Initial results of finger imaging using Photoacoustic Computed Tomography
Peter van Es, Samir K. Biswas, Hein J. Bernelot Moens +2
We present a photoacoustic computed tomography investigation on a healthy human finger, to image blood vessels with a focus on vascularity across the interphalangeal joints. The cr…
A new acoustic lens material for large area detectors in photoacoustic breast tomography
Wenfeng Xia, Daniele Piras, Johan C. G. van Hespen +2
Acoustic lenses made of acrylic plastic (PMMA) have been used to enlarge the acceptance angle of sensitive large surface area detectors and improve lateral resolution. However, PMM…
The 'nanobig rods' class of gold nanorods: optimized dimensions for improved in vivo therapeutic and imaging efficacy
Constantin Ungureanu, Gerben A. Koning, Ton G. van Leeuwen +1
Currently, gold nanorods can be synthesized in a wide range of sizes. However, for intended biological applications gold nanorods with approximate dimensions 50 nm x 15 nm are used…
An optimized ultrasound detector for photoacoustic breast tomography
Wenfeng Xia, Daniele Piras, Johan Van Hespen +5
Photoacoustic imaging has proven to be able to detect vascularization-driven optical absorption contrast associated with tumors. In order to detect breast tumors located a few cent…
Speed-of-sound compensated photoacoustic tomography for accurate imaging
Jithin Jose, Rene G. H. Willemink, Wiendelt Steenbergen +3
In most photoacoustic (PA) measurements, variations in speed-of-sound (SOS) of the subject are neglected under the assumption of acoustic homogeneity. Biological tissue with spatia…
