On-Site Medical Imaging

Our Mission

The mission of On-Site Medical Imaging is to deliver quality health care and portable diagnostic imaging in a safe, efficient manner. We offer a respectful and convenient service to our patients. We provide cost-effective solutions to our clients by utilizing the latest diagnostic technology available and employ caring professionals who share the same commitment.

Our Purpose

The portable x-ray industry saves Medicare over $2.5 billion annually on fees that are spent on unnecessary ambulance and hospital admissions. Further, economists agree that due to the number of Americans between the ages of 60-75, the need for health care in this country will vastly increase to support the Baby Boomer population.

According to the Centers for Disease Control and Prevention (CDC), in the year 2000, there were roughly 35.6 million Americans aged 65 years and older. By 2030, this number is projected to double to an estimated 71.5 million.

Our purpose is serve our patients in an environment that is safe and comfortable to them, and to provide our clients with the benefits of having their own radiology department without the burden of having to maintain the cost of such an operation.

“On-Site Medical Imaging has provided us with excellent personalized service. By collaborating with our IT Department to enhance our technology, our x-ray results are timely and available to view by computer. On-Site Medical Imaging has reduced outside hospital trips by 3-4 per month by providing on-site ultrasonography. I have been impressed by the company’s responsiveness to our needs, whether it is the timeliness of routine results, STAT x-rays, or providing us another courtesy service when we are in need. I would highly recommend them for x-ray and diagnostic services in a correctional institution.”

“The staff is professional, efficient, and very responsive. They all go the extra mile to get the x-ray done as urgently as I need and get the result to me quickly – as I so often seem to need late on a Friday afternoon. I feel I can rely on On-Site Medical Imaging as a trusted colleague, and I highly recommend them.”
