Raymond Vahan Damadian (born March 16, 1936 – died August 3, 2022) was an American doctor and scientist. He is famous for inventing the first machine that could scan the human body using magnetic resonance imaging (MRI). This amazing technology helps doctors see inside our bodies without surgery.
Dr. Damadian's early studies looked at tiny particles like sodium and potassium inside living cells. This research led him to explore a scientific method called nuclear magnetic resonance (NMR). He realized that NMR could show differences between healthy tissues and tumors (growths that can be cancerous). This was because these tissues had different "relaxation times" when exposed to magnetic fields.
In 1969, Dr. Damadian suggested that an NMR machine could scan the human body. Later, in 1977, he successfully performed the very first full-body scan of a person to look for cancer. He created a safe and accurate way to use NMR for scanning, which we now call MRI.
For his groundbreaking work, Dr. Damadian received many awards. These included the Lemelson–MIT Prize in 2001, which recognized him as "the man who invented the MRI scanner." He also received the National Medal of Technology in 1988 and was added to the National Inventors Hall of Fame in 1989.

Discovering MRI: Raymond Damadian's Story
Early Life and Education
Raymond Vahan Damadian was born in New York City on March 16, 1936. His family was Armenian. His father, Vahan, worked as a photoengraver (someone who makes printing plates for pictures). His mother, Odette, was an accountant.
Raymond was a bright student. He earned a degree in mathematics from the University of Wisconsin–Madison in 1956. Then, he became a medical doctor, graduating from the Albert Einstein College of Medicine in 1960. Besides science, he loved music and played the violin for eight years at Juilliard. He also enjoyed sports, competing in junior Davis Cup tennis.
He married Donna Terry and they had three children. Raymond's interest in finding a way to detect cancer started when he was just 10 years old. He saw his grandmother, whom he loved very much, suffer from breast cancer. This sad experience inspired him to dedicate his life to medical research.
How MRI Technology Works
Dr. Damadian's early research focused on how tiny particles like potassium behave inside cells. He noticed that these particles acted differently in cells compared to plain water. This suggested that the water inside our bodies is not just free-flowing, but organized in a special way.
He and other scientists also studied signals from hydrogen atoms in cells. They found that these signals had different "relaxation times" in healthy tissues. Dr. Damadian believed that cancerous cells would have even longer relaxation times. This was because cancer cells are often more disorganized and have higher levels of potassium.
In 1971, Dr. Damadian published an important paper in the journal Science. He explained that tumors could be found inside the body using nuclear magnetic resonance (NMR). This was because tumors had much longer relaxation times than normal, healthy tissue. He thought this difference could help detect cancer early, when it's easiest to treat.
In 1972, Dr. Damadian applied for a patent for his idea. In 1974, he received the first patent in the field of MRI. This patent described using NMR to "scan" the human body to find cancerous tissue. While it didn't explain how to create pictures, it was a key step. Dr. Damadian's discovery that NMR relaxation times could tell different tissues apart is what gives MRI its amazing ability to show clear images of soft tissues.
Other scientists also contributed to MRI. Herman Carr created a basic magnetic resonance image in one dimension. Inspired by Damadian, Paul Lauterbur developed a way to make the first 2D and 3D MRI images using special magnetic fields called gradients. Peter Mansfield then found a mathematical technique to make scans much faster and clearer. While Lauterbur and Mansfield worked on animals and body parts, Dr. Damadian built the first full-body MRI machine. In 1977, he performed the first full-body scan of a human.
The First Human MRI Scan
On July 3, 1977, Dr. Damadian and his team, Larry Minkoff and Michael Goldsmith, performed the first full-body MRI scan on a human. It took nearly five hours to create just one image of Larry Minkoff's chest. The images were simple compared to today's detailed scans.
They named their first machine "Indomitable," meaning "unbeatable." This name reflected their determination to achieve something many thought was impossible. Dr. Damadian's work showed that it was possible to use NMR to look inside the human body.
His discovery of different NMR signals in various tissues was crucial. As one book on MRI history noted, "Without Damadian's discovery, it could not be known that serious diseases like cancer could be detected by an NMR scanner or that tissue NMR signals possessed sufficient contrast to create medically useful images."
In 1988, the President of the United States, Ronald Reagan, honored both Dr. Damadian and Dr. Lauterbur. They received the National Medal of Technology for their independent contributions to developing MRI for medical use. Dr. Damadian's original MRI machine is now displayed at the Smithsonian Institution. Today, there are thousands of MRI scanners helping people around the world.
Fonar Corporation and Innovations
In 1978, Dr. Damadian started his own company called Fonar. The name stood for "Field Focused Nuclear Magnetic Resonance." In 1980, Fonar produced the first commercial MRI scanner.
Fonar continued to innovate in MRI technology. Dr. Damadian later worked with Wilson Greatbatch, who helped develop the implantable pacemaker. Together, they worked on creating pacemakers that would be safe for people to use with MRI machines.
Dr. Damadian also invented a special "stand-up" MRI system. This allows patients to be scanned while standing or sitting, which can be helpful for certain conditions. In 2007, his company's Upright Multi-Positional MRI was recognized as the "Invention of the Year."
Personal Beliefs
Raymond Damadian was a lifelong Christian.
Passing Away
Dr. Raymond Damadian passed away on August 3, 2022, at the age of 86. He died from cardiac arrest.
