of 250 ms the heart-rate independent temporal resolution for example in cardiac imaging is now 66 ms. Since SOMATOM Force can apply this scan mode together with a fast acquisition speed it allows free-breathing CT imaging in many cases. Learn more about the benefits of Dual Source technology....
A CT scan helps your doctor select the correct location for surgery, biopsy, or radiation therapy, check the treatment of cancer or heart disease, and check your condition after surgery. ACT scanneris a large square or round x-ray machine with a tun...
