S
E A T T L E Armed with a $3.6 million
grant, University of Washington researchers
are developing, among other things, a portable
ultrasound device that could find and cure ailments
without surgery.
An
ultrasound machine can identify internal injuries,
and scientists have discovered that heating
tissues with an beam from the device also can
stop internal bleeding and kill cells of tumors,
UW researcher Michael R. Bailey said Friday.
"I
feel weird talking about it. It sounds like
'Star Trek'," Bailey added, referring to
gizmos used by the space travel epic's Dr. "Bones"
McCoy.
'Cooking'
Human Tissue
"That's
the idea," said Dr. Martin Kushmerick,
UW professor of radiology, bioengineering, physiology
and biophysics. "That's not entirely far-fetched."
UW
researchers were awarded the grant over the
next three years by the National Space Biomedical
Research Institute, a 12-institution consortium
to study space medicine.
The
goal of the consortium, in conjunction with
NASA, is to research whether astronauts could
survive a planned 2014 mission to Mars
a six-month trip to a planet with about 40 percent
of the gravity of Earth, said Kushmerick, who
is heading scientists from five institutions
studying the body's response to traveling in
space for long periods.
The
UW team received $900,000 to create a model
of a battery-powered ultrasound device to provide
medical help to astronauts in deep space, Bailey
said.
"For
our application, we're proposing a fix to keep
someone alive," Bailey said.
Scientists
are studying the long-term effects of "cooking"
the tissue, as well as overcoming any obstacles
to using such a machine in space.
"We're
fairly certain it works on the ground,"
Bailey said. "We think there will be some
challenges for working in space."
Dr.
Lawrence Crum, director of the Center for Industrial
and Medical Ultrasound at the UW's Applied Physics
Laboratory, was named co-team leader of the
consortium program "Smart Medical Systems,"
which includes the ultrasound device.
Bailey
said Crum has received requests from cancer
patients to try curing them using an ultrasound
machine.
"Legally,
we're in no position to do that," he said.
"We're moving as fast as we can, but we
can't do that."
Kushmerick's
team is also working to create "the digital
human," a series of mathematical problems
to figure out how everything from molecules
to cells to organs work together to determine
the effects of space travel on the body.
