Spatial Frequency Math: What is the spatial frequency (lp/mm) for a pixel size of 148 um?

### The spatial frequency for a pixel size of 148 um is 3.38 lp/mm.

## Step1: Conversion of Units### The pixel size is given in microns (um), but spatial frequency is typically measured in line pairs per millimeter (lp/mm). Therefore, we first need to convert the pixel size from microns to millimeters. Since 1 mm equals 1000 um, we divide the pixel size in microns by 1000 to get the size in millimeters.## Step2: Calculation of Spatial Frequency### The spatial frequency (SF) is calculated using the formula SF = 1 / (2 x Pixel Size). We substitute the pixel size in millimeters into this formula to calculate the spatial frequency.
