New takes on image guidance for radiation therapy August 24, 2012 -- Kilovoltage and megavoltage conebeam CT are predominantly used for real-time imaging during radiation therapy, with systems based on ultrasound or MRI now also being developed. But there are other imaging modalities that could be used, including those that offer functional and molecular information regarding the tumor being treated.
Radiologists vary DR image quality to optimize radiation dose August 24, 2012 -- A new Chinese study questions the assumption that striving for the highest possible image quality is always the best approach. Researchers developed an x-ray optimization strategy that cuts the dose of digital radiography (DR) substantially by adjusting dose levels based on the type of exam being conducted.
CMS releases final rule for stage 2 meaningful use August 23, 2012 -- The U.S. Centers for Medicare and Medicaid Services (CMS) has released its final rule for stage 2 meaningful use, which now includes the viewing of medical images as a menu item in the U.S. government's healthcare IT stimulus program.
