X-Ray, Biomedical and Laboratory Sales and Service Universal Medical Services was started over twenty years ago to lower the cost of imaging service to local hospitals. Since then, UMS has grown in size and scope and has become the largest independent imaging and biomedical service provider in the region. We currently service x-ray, nuclear medicine, ultrasound, CT/MRI, biomedical equipment, processors, and sterilizers. UMS provides resident in-house, contract and hourly service to our hospitals, imaging centers, clinics and office based customers
