Photoacoustic Imaging and Its Biomedical Applications

Dear Colleagues,

Photoacoustic imaging, also known as optoacoustic imaging, is an emerging biomedical imaging modality that integrates the molecular contrast of optical imaging with the high spatial resolution of ultrasound imaging in deep tissue by converting absorbed light into acoustic waves. By providing structural, functional and molecular information with a variety of endogenous and exogenous contrast agents, photoacoustic imaging has demonstrated potential in many biomedical/medical applications. Tremendous progress has been made in photoacoustic imaging over the preceding decades regarding preclinical research and clinical imaging such as organelle and cellular activity tracking, vascular and disease physiology assessment, surgery guidance, drug delivery and therapy monitoring. On the other hand, rapid growth in technical innovations, including ultrasonic detectors, computations, and lasers, has enabled photoacoustic imaging to become amongst the largest research areas in biophotonics. The aim of this Special Issue, entitled “Photoacoustic Imaging and Its Biomedical Applications”, is to publish original research and reviews within the photoacoustic/optoacoustic imaging and relevant fields, presenting the current state-of-art development in all aspects of photoacoustic imaging. The list of topics of interest includes (but is not limited to) the following:

• Technical innovations in photoacoustic tomography, mesoscopy, microscopy, and nanoscopy;
• Contrast agents, molecular probes, and nanotechnologies;
• Functional and molecular imaging and sensing;
• Preclinical/clinical imaging and applications, clinical translation;
• Advanced signal processing, filtering, image processing and imaging reconstruction algorithms including deep learning;
• Multi-modality systems, biomedical and clinical applications involving acoustics and optics;
• Microwave and X-ray induced ultrasound imaging and sensing;
• Laser ultrasound technologies;
• Novel light delivery and ultrasound sensing technologies;
• Interactions with cells and tissues.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Photonics is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
