Purpose: The imaging features of patients with early-stage non-small cell lung cancer (NSCLC) receiving stereotactic body radiotherapy (SBRT) are crucial for the decision-making process to … WebSo we’re going from 140 kVp to 70 kVp. Originally we needed 100 mA. So what do you think we’re going to need for the mA if we go from 140 kVp down to 70 kVp? We’re going to need about 400 mA because our new mA has to compensate for the fact that the kVp is the biggest driver and that goes approximately as the square of the kVp. hans zimmer genre of musicWebBiomedical Engineering Medical Imaging - 2024 5 Figure 5.
