Siemens unveils CT dose reduction
New software shown by Siemens at the RSNA meeting promises to cut patient exposure to x-rays by as much as 60% for a wide range of CT applications.
New software shown by Siemens at the RSNA meeting promises to cut patient exposure to x-rays by as much as 60% for a wide range of CT applications. The iterative reconstruction package, dubbed iterative reconstruction in image space (IRIS), is expected to begin shipping next year on new Somatom Definition CT scanners, including the dual-energy Definition Flash CT. An upgrade is being developed for installed Definition systems.
The software minimizes computing time, according to the company, by accelerating the convergence of the reconstruction. It does so by applying the raw data reconstruction only once. During this newly developed initial raw data reconstruction, a “master image” is generated that contains all the raw data information. The following iterative corrections are then performed consecutively in the image space. The resulting images are reduced in artifacts and noise, show increased image sharpness, and are created at a dose savings up to 60%, according to Siemens.
Can Innovations with AI Help Address the Impact of Staffing Shortages on Radiology Workflow?
October 7th 2024While staffing shortages in radiology continue to persist after the COVID-19 pandemic, current and emerging innovations powered by artificial intelligence (AI) may help facilities navigate these challenges and mitigate rising costs of health care.
CT Study Links Pleural Effusion and Higher 30-Day Mortality Rates in Patients with COVID-19
October 1st 2024In a multicenter study of over 1,100 patients with COVID-19, pleural effusion was detected on CT scans in nearly a third of patients, who also had significantly higher ICU admission and 30-day mortality rates.
