Computerized
Ultrasound Risk Evaluation (CURE) system, developed by KCI and SciTech,
will fulfill the mission to provide a significant clinical improvement
at a reduced cost. The CURE research & development team’s enhancement of
ultrasound technology has resulted in imaging capabilities superior to
current devices.
Utilizing the existing ring array configuration,
experiments have been preformed to show that time reversal (TR) focusing
could be used in non-invasive drug delivery procedure. TR focusing uses
an iterative approach to determine the waveform required for transmittal
from each element of the array to achieve the optimum focusing on a
selected target. The major potential benefit for breast imaging and
treatment would be that TR focusing is not susceptible to distorting
mediums, such as the highly scattering combination of breast fat and
parenchyma. Using the TR approach, ultrasound has the potential to be
tightly focused in tissue for the treatment of cancerous tumors, using
either direct ablation or targeted drug delivery via local rupture of
liposomes containing a therapeutic agent. Specialized drug formulations
and dosage forms are being devised to match the technical specifications
of the CURE system so that tissue exposure occurs only at the exact
area(s) of breast disease identified by the CURE system.
18 million
mammograms are conducted annually in the US, and yet 10-15% evaded
cancer detection. Even though women with suspicious masses have a
follow-up ultrasound (US), breast cancer remains the second leading
cause of death for woman. An obvious need exists for better, more
reliable and accurate technology.
