TORONTO, April 7 /CNW/ - Segasist Technologies, a Canadian software
company developing automated image contouring methods for biomedical
applications announced today the successful completion of validation
studies of its software for prostate auto-contouring.
Segmentation of the prostate gland in different modalities can be time
consuming and may be subject to inter- and intra-observer variability.
"The purpose of this validation was to perform a rigorous technological
assessment and validation, in terms of accuracy, time-savings and
ergonomics, of a software package/algorithm that can auto-contour
prostate MRI datasets," says Dr. George Rodrigues, the principal
investigator and a radiation oncologist at London Health Sciences
The multi-phase validation, conducted by several radiation oncologists,
started in September 2010 and ended in February 2011. "The Segasist
auto-contouring software has been validated to assist clinicians in the
segmentation of prostate MRI datasets in terms of contouring time and
accuracy," states the executive summary of the validation report, "This
auto-contouring algorithm provides robust contours that, in general,
require minimal additional editing by the user. The observed
time-savings were seen for all physicians irrespective of experience
level and baseline manual contouring speed."
Segasist software is the first commercial software of its kind providing
a complete solution for segmentation and volumetric measurements of the
prostate gland in MR images. The software can perform auto-contouring
in CT scans and ultrasound images as well. The validation study was
supported by Precarn Inc. and Health Technology Exchange (HTX).
"The positive results of the clinical validation are extremely
encouraging for us," says Hamid Tizhoosh, CEO of Segasist Technologies,
"this will not only assist us to get the software to the hospitals,
after we have regulatory approval, but will also pave the road to fully
exploit the immense potentials of our technology for future products."
