// The following list just contains typical values of tissue densities
// And a rough guess of the HU value for monochramtic radiation with 70keV
// For detailed information refer to ICRP Publication 23 and ICRU Report 44 
// We could decide that a contrast below 20 HU (= 2% difference) is "low" by definition
