Summary
Objectives: In this synopsis, we identify and highlight research papers representing noteworthy
developments in signals, sensors, and imaging informatics in 2021.
Methods: A broad literature search was conducted on PubMed and Scopus databases. We combined
Medical Subject Heading (MeSH) terms and keywords to construct particular queries
for sensors, signals, and imaging informatics. Except for the sensor section, we only
consider papers that have been published in journals providing at least three articles
in the query response. Using a three-point Likert scale (1=not include, 2=maybe include,
and 3=include), we reviewed the titles and abstracts of all database returns. Only
those papers which reached two times three points were further considered for full
paper review using the same Likert scale. Again, we only considered works with two
times three points and provided these for external reviews. Based on the external
reviews, we selected three best papers, as it happens that the three highest ranked
papers represent works from all three parts of this section: sensors, signals, and
imaging informatics.
Results: The search for papers was executed in January 2022. After removing duplicates and
conference proceedings, the query returned a set of 88, 376, and 871 papers for sensors,
signals, and imaging informatics, respectively. For signals and images, we filtered
out journals that had less than three papers in the query results, reducing the number
of papers to 215 and 512, respectively. From this total of 815 papers, the section
co-editors identified 35 candidate papers with two times three Likert points, from
which nine candidate best papers were nominated after full paper assessment. At least
three external reviewers then rated the remaining papers and the three best-ranked
papers were selected using the composite rating of all external reviewers. By accident,
these three papers represent each of the three fields of sensor, signal, and imaging
informatics. They were approved by consensus of the International Medical Informatics
Association (IMIA) Yearbook editorial board. Deep and machine learning techniques
are still a dominant topic as well as concepts beyond the state-of-the-art.
Conclusions: Sensors, signals, and imaging informatics is a dynamic field of intense research.
Current research focuses on creating and processing heterogeneous sensor data towards
meaningful decision support in clinical settings.
