Low Radiation CT Scans Thanks to Novel Device
Overuse of high radiation diagnostic devices has caused
occurrences of cancer to increase exponentially. According to an article in the
journal Archives of Internal Medicine, 70 million CT scans were done in the
United States alone in 2007, up from 3 million in 1980. Further, out of those
patients who underwent CT scans in 2007, 29,000 of them are expected to develop
cancer. It has become undeniable that overexposure to radiation is a health
hazard that significantly increases a patient’s risk of developing cancer.
Public awareness of the health risks associated particularly with CT Scans
alongside climbing imaging costs to pay for Health Reforms make radiation
imaging less attractive to patients over other imaging methods. This pressure
has caused industry imaging manufacturers like General Electric Co, Siemens AG
and Philips Electronics NV to be strongly motivated to turn around public
opinion by developing safer radiation based imaging equipment.
Despite the fact that there are safer imaging devices like MRI and Ultrasound,
CT is still
widely used because it is ideally suited for viewing and quickly diagnosing
internal bleeds and stroke, which in emergency situations, justifies using CT in
spite of the health risks.
This has left a niche area open for medical device companies to create
innovative solutions for CT scanners that facilitate reducing radiation dosages
while maintaining high image quality. In answer to this need, Company Medic
Vision Imaging Solutions, has developed and commercialized the SafeCT device,
which is compatible with any CT Machine.
SafeCT is an add-on device for CT equipment. Through image post-processing
using a 3D non-linear noise reduction algorithm, SafeCT compensates for the
image quality lost in low radiation dosages. According to Medic Vision’s
testing, they were able to produce diagnostic quality images at reduced
radiation dosages of up to 77%.
Innovations like Medic Vision’s SafeCT device help significantly lower the
risk of patient radiation exposure, however it is as of yet unknown whether this
will be enough to remove all health risks associated with radiation imaging.
Clearly further research is needed in this area.
