Advances in Ultrasound Sensor and Ultrasound Imaging

Dear Colleagues,

Ultrasonic sensor and imaging technologies have been developed for more than one hundred years, and there are four main application scenarios: underwater scenarios, airborne scenarios, and in solid and biological tissues. For all of these scenarios, ultrasound imaging performance depends on two cascaded signal processing steps: (1) acoustic sensing including acoustic capturing, acoustic–electric transition, and real-time signal conditioning, accomplished by the ultrasound sensor; (2) signal processing accomplished by the ultrasound imaging algorithms. The performance of all the ultrasound imaging algorithms in step (2) can be enhanced with advances in the ultrasound sensors in step (1) since they are combined in series. Therefore, we would like to see ultrasound imaging technology driven by advances in ultrasound sensors. Ultrasonic sensors can be based on disruptive concepts or can be an improvement of traditional devices, but they must be used for the purpose of imaging. These new alternatives could be equally efficient and less expensive, or equally cheap and higher performance, compared with existing sensors. We also welcome ultrasonic sensors and imaging technologies for some special applications. Potential topics include, but are not limited to, the following:

• New ultrasound sensors with advances in acoustic capturing, acoustic-electric transition, or real-time electrical signal conditioning;
• Acoustic metamaterial devices equipped with conventional or new ultrasonic sensors;
• New ultrasound imaging techniques driven by advances in ultrasound sensors;
• Theoretical and experimental investigations of the influences of ultrasound sensor performance on ultrasound imaging performance.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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.
