Leeds Test Objects

Leeds Test Objects is a private UK medical device company that designs and manufactures medical imaging quality assurance phantoms and related analysis software. Its products are used to test, calibrate, and monitor image quality and system performance across X-ray, fluoroscopy, radiography, mammography, dental imaging, CT, MRI, ultrasound, nuclear medicine, and radiotherapy workflows. The company appears to be a commercial-stage manufacturer rather than a therapeutics developer, with a long operating history in imaging QA and a product lineage dating back to 1955. Leeds Test Objects serves hospitals, medical physics departments, radiographers, and multinational imaging organizations through direct sales and distributor networks. It is best classified as a healthcare imaging QA and medtech tools company, not a biotech or pharma drug-development company.
