Advances in Electrical Capacitance Tomography System

Dear Colleagues, 

Electrical Capacitance Tomography (ECT) has found application as a process visualization tool in chemical engineering, especially in multiphase flow monitoring. The possibility of using this technique in medical imaging using contactless electrodes is being investigated. However, the imaging quality and performance of ECT systems currently available are limited due to low spatial sampling, low sensitivity, and nonlinearity of the tomographic inverse problem. Several research groups are conducting new studies in sensor design, capacitance measurement methods, hardware development, digital signal processing, and image reconstruction to improve image quality.

This special issue intends to highlight the research that supports the development of the theories and technologies underlying the design of ECT systems. Both theoretical contributions and practical validations are essential. Topics of interest include, but are not limited to:

• 2D and 3D capacitance sensor design and modeling
• methods of capacitance measurement and signal conditioning
• complex-valued capacitance measurement and multi-modal imaging
• data acquisition system architecture for real-time imaging
• high-speed nonlinear image reconstruction
• image processing and process control

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 250 words) can be sent to the Editorial Office for assessment.

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. Electronics 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.
