Emilio Segrè Visual Archives

More than 30,000 photos of scientists and their work

Attention ESVA patrons:

The Emilio Segrè Visual Archives’ site is moving soon and adopting an open access approach to digital image sharing. Once we have transitioned to the new site in 2021, we will no longer charge for our high-resolution digital images or usage fees (note that we do not hold copyright to all the images in our collections and you will still need to obtain permission for those which we do not own).

If you are working on a long-term project, we advise you to wait until the migration is complete so that you may obtain our copies for free. If you cannot wait, email us at nbl [at] aip.org and we will do what we can to assist you. We will not be offering refunds for past purchases.

For more information, please visit our FAQ page on the Ex Libris Universum blog.

We charge a usage fee per photo if the photo is published, reproduced in a product or publicly exhibited. This is not a license in the legal sense. As a non-profit institution, we do not make any money providing these photographs. It is only by assessing usage fees that we are able to cover the cost of providing publication quality copies of our photos, preserving the photograph collection according to archival standards, and providing access to the collection by maintaining an online image database. The copyright holder may charge a fee in addition to our service fee.

Images are for use in educational projects only and must be used in a respectful manner.

'WORLD'S FIRST. With the help of magnetic fields 30,000 times as strong as the earth's, a General Electric scientist has for the first time been able to perform chemical analysis of a living human heart by non-invasive means. This first was achieved by Dr. Paul A. Bottomley (photo), a physicist at the GE Research and Development Center in Schenectady, N. Y., employing a GE-pioneered technique called depth-resolved magnetic resonance (MR) spectroscopy. By means of powerful magnetic fields, radio waves, and a computer, it can sample the chemistry of living body tissues without cutting a patient open or inserting any probes. Here, Dr. Bottomley examines MR spectra showing the relative amounts of energy-producing phosphorus compounds in the heart of a normal male volunteer. The fact that the amounts of these chemicals change according to the heart's state of health could provide clues that would enable physicians to evaluate heart disease and monitor its response to therapy. On the screen is an MR image showing the subject's heart and other organs.' August 22, 1985 press release. Magnetic resonance imaging
