In fact, it can be as fast as 30 frames each second. The first x-ray machine took hours to receive the data for just one scan or what is called a ‘slice’ involving metrology. Then, it would take several days to reconstruct an image from the raw data. Nowadays, x-ray systems can collect up to four slices of data is approximately 350 milliseconds and the reconstructing can be done in less than a second. It really is amazing how far technology has come.
