This calculator calculates the absorbed dose of radiation to the breast in mammography using kerma, hvl, x-ray spectra values.
Mean glandular dose (MGD) is a quantity used to describe the absorbed dose of radiation to the breast in mammography. It is based on a measurement of air kerma and conversion factors.
Formula:
D=K×g×c×s
Where,K is kerma
g converts from incident air kerma to MGD with a glandularity of 50%, based on breast thickness and HVL
c corrects for glandularity other than 50%, depending on the breast thickness and HVL
s corrects for the x-ray spectra in use with a table of target/filter combinations
