Imaging Diagnostic Systems develops new algorithm for CT laser
mammography
8 April 2009
Imaging Diagnostic Systems, Inc., (OTCBB:IMDS) a pioneer in laser
optical breast cancer imaging systems, has enhanced its CT Laser
Mammography (CTLM) system with a reconstruction algorithm that improves
visualization of angiogenesis (cancer) in its images.
During a CTLM examination the breast is illuminated by a laser and
the transmitted light is collected by a series of photo detectors and
transformed into digital data. The reconstruction algorithm uses this
data to create the various images of the breasts. The improved algorithm
enhances the images by reducing the number of artifacts occasionally
produced during an examination thereby making diagnosis easier.
Steven Ponder PhD, Director of Advanced Development/Imaging
Diagnostic Systems, said, “Our first-generation reconstruction
algorithms were developed and evaluated using data acquired during our
initial clinical trials. Since those trails, we have deployed over 26
systems worldwide, providing us with CTLM data from thousands of
patients.
"IDSI’s Research & Development team used this data to optimize the
reconstruction algorithms in order to provide better clarity and reduced
artifact in CTLM images. We also incorporated streamlined numerical
methods into the software so that the new algorithm does not require
additional computing resources, allowing us to provide the improved
functionality to existing customers as a software upgrade.”
Dr Eric Milne Director of Clinical Research/Imaging Diagnostic
Systems Inc, said, “The new algorithm has improved the visualization and
distinction of several known patterns of angiogenesis from normal
patterns of breast perfusion, making it easier for the radiologist to
detect cancer.
"Of even greater importance; breasts which are too dense to be
penetrated by X-ray mammography are quite translucent to the laser beam.
The CTLM system therefore has much greater sensitivity than mammography
in the dense breast and can reveal between two and three times the
number.”
