Who is ARTHUR?

ARTHUR is a Rheumatoid Arthritis Ultrasound Robot that interacts directly with the patient without the need of an ultrasound specialist. ARTHUR will capture high quality ultrasound images in grayscale and colour flow of 11 joints per hand. This includes 10 finger joints and 1 wrist joint  (MCP, PIP and RC-IC joint).

ARTHUR offers an uniform and automatic process to capture the images and all images are quality ensured by a built in Artificial Intelligence module. This ensures high consistency and quality  in ARTHURs images every time- there is no operator dependence in quality.

Patients in our studies and surveys are happy to have ARTHUR as a part of their monitoring and up to 92% found the experience of being scanned by ARTHUR as good or very good.
