New CT Scan Method Lowers Radiation Exposure – techtoday19
A CT scan technique that splits a full X-ray beam into thin beamlets can deliver the same quality of image at a much reduced radiation dose, according to a new UCL study Related Content In I-131 cancer therapy, decay events damage sensitive DNA within a tumor…
Fig. 1 The basis of high-sensitivity SPION imaging at ultra-low magnetic fields.
(A) Magnetization of 25-nm SPIONs (green), gadolinium CA (Gd-DTPA/Magnevist, blue), and water (red) as a function of magnetic field strength (B0). (B) Magnetization as a function of magnetic field strength (B0) in the ULF (<10 mT) regime for the materials shown in (A). Superparamagnetic materials, such as SPIONs, are highly magnetized even at ULF. Paramagnetic materials, such as CAs based on gadolinium, and body…
