convert gray level to dB (decibel)

#1 Post by posiadacz » Thu, 2011-07-14, 09:49


I have a problem converting the luminosity of pixels read from the DICOM file to dB (decibels). Please help me to convert the pixels stored in the DICOM file on the dB (formulas?). What is the formula needed to be converted? (20 log10 (gray level/...??)). I can not find how to convert.

Have a nice day
