AN article in one of the Institute of Physics and Engineering in Medicine’s three internationally-renowned journals has set a new record after gaining more than 1,000 citations.
IPEM member Dr John Allen, senior research scientist in microvascular diagnostics at the Newcastle Upon Tyne Hospitals NHS Foundation Trust, wrote the article for Physiological Measurement, published by IPEM in partnership with the Institute of Physics Publishing.
His article ‘Photoplethysmography and its application in clinical physiological measurement’ is the first one to have ever amassed so many citations in the journal. The previous record number of citations for an article in Physiological Measurement was 470.
Dr Allen said: ‘Photoplethysmography (PPG) is a simple low-cost vascular optics technique that can detect pulsatile blood volume changes in skin tissue with each heartbeat. The core technology lends itself to miniaturization and also for use in digital e-health systems.
‘There is considerable global academic and industrial interest in PPG, with it utilised extensively in pulse oximeter devices, wearable sensors - including personal health monitors and watches, imaging systems, and also bespoke research devices for targeted cardiovascular assessment.
‘Recent advancements in signal processing techniques, including machine learning and Artificial Intelligence (AI), have also opened up new and exciting opportunities in PPG-based medical diagnostics.’
