Creating
clearer Imaging to spot cancer earlier and more accurately.
When
biomedical engineer Muyinatu Lediju Bell was an undergraduate at MIT, her
mother died of breast cancer. Bell thought her mother might have survived if
she had been diagnosed sooner, so she decided to investigate what makes some
ultrasound images blurry, a problem that limits a doctor’s ability to screen
for and diagnose cancer and other diseases.
As
a doctoral candidate at Duke University, Bell developed and patented a novel
signal processing technique that produces clearer ultrasound images in real
time. The solution could particularly help diagnose problems in people who are
obese, because fat tissue can scatter and distort ultrasound waves, delaying
the detection of a serious disease. “I think it’s unfair that a long-standing
technology does not serve a huge group of people that should be able to benefit
from it,” she says.
Beyond
ultrasound, Bell is now working to improve another type of noninvasive medical
imaging technique. Called photoacoustic imaging, it uses a combination of light
and sound to produce images of tissues in the body. She is especially
interested in using it for real-time visualization of blood vessels during
neurosurgeries to lower the risk of accidental harm to the carotid artery,
which supplies blood to the brain. Her lab at Johns Hopkins plans to launch a
pilot study of the technology in patients in 2017.
