2. Computer software aids in reducing dose
Through initiatives like Image Gently and Image Wisely, limiting lifetime ionizing radiation dose exposure has moved into center stage as a key objective in medical imaging — that means performing exams more efficiently and cutting down on unneeded scans.

Today, there is an entire software market segment dedicated to getting as much as possible from a CT image with radiation doses 'as low as reasonably achievable.' That includes solutions for iterative reconstruction, intraoperativity, and dose-tracking.
Dose knowledge is crucial
With the advent of XR-29, providers who are not incorporating dose monitoring into their CT scanners are being penalized for it. As of January, it can cost them 15 percent of their reimbursement on certain exams.
Last May, HCB News reported that Dr. Ruogu Fang applied machine learning and mathematical algorithms
to manipulate low-dose CT perfusion images on stroke patients. When reconstructed, these low-dose images provided comparable image quality with just eight percent of the radiation needed to produce traditional, high-dose images.
There have also been CT studies of late that show that scanning can be of benefit in certain populations to catch cancer earlier, which shows both the risks and rewards of the modality.
