Web26 de nov. de 2024 · ADC values of high b values were obtained and recorded for all 60 solid head and neck masses detected at consensus reading. Malignant lesions group ( n = 28): ADC values ranged between 0.530–1.290 s/mm 2. The mean ADC value of malignant lesions was 0.82 ± 0.19 (Figs. 1, 2, and 3 ). WebSo if we assume your input voltage ranges from 0-50V, we need to divide it by 10 to achieve 0-5V. If we also assume we want to load the input voltage with 100kΩ, then the calculations would something like: Vout / Vin = R2 / 100kΩ. 0.1 = R2 / 100kΩ -> R2 = 10kΩ. R1 = 100kΩ - R2 = 90kΩ. So R1 = 90kΩ and R2 = 10kΩ.
