New director named at APL
It's no easy thing to decide to leave an organization where
you've worked since you graduated from college more than 30 years
ago. But Rich Roca has been getting a lot of feedback that the
decision was the right one.
"When I tell people that I'm going to be
director of the
Applied Physics Laboratory, standard reaction has been, "'Wow!'"
Roca said. "APL's reputation is very widely held."
Roca, a vice president of AT&T Labs, the
company's research and development arm, will join Johns Hopkins
as the seventh director of APL on Jan. 1. He was appointed by the
university's board of trustees last week on the recommendation of
President William R. Brody.
'HARP MRI' takes faster look at
Johns Hopkins engineers have developed a system that can give
doctors--almost immediately--detailed images showing where heart
damage has occurred. In the very near future, the inventors say,
cardiologists routinely will be able to see clearly the condition
of heart muscles while a patient is still inside a magnetic
resonance imaging scanner.
Currently, it is too costly and impractical
for physicians to use an MRI scanner to examine the heart during
a typical cardiac stress test. Even though an MRI, coupled with
cutting-edge "tagging" technology, can provide highly detailed
heart data, it is rarely used because the pictures take several
hours to process and interpret. To eliminate this delay, Jerry
Jerry L. Prince and Nael Osman of the Whiting School of
Engineering have developed HARP MRI, a system that allows doctors
to see the condition of the heart muscles in minutes, not hours.
