This tool calculates the effective dose (mSv) with respect to the DAP value (e.g. cGy.cm2)
belonging to different types of radiograph. It does for instance, Gy.cm2 to mSv conversion. It is emphasized that the result is
an estimation. The conversion factor relates to ICRP 103 and is obtained from: Radiation
risks from medical x-ray examinations as a function of the age and sex
of the patient,

The publication gives different types of radiograph and their conversion factors: Head AP, Head PA, Head Lat, Cervical spine AP, Cervical spine Lat, Shoulder AP, Shoulder (axial), Chest PA, Chest Lat, Thoracic spine AP, Thoracic spine LAT, Lumbar spine AP, Lumbar spine Lat, Lumbo spine Lat, Lumbo-sacral joint Lat, Apdomen AP, Pelvis AP, Single Hip AP, Both Hips AP, Femur AP, Femur Lat, Knee AP, Knee Lat, Foot (dorsi-plantar), Foot (oblique)

Is everything correct? Everywhere in the publications the effective dose for chest imaging is given as 0.02 mSv. But here in the calculator the values come out as 0.0002 mSv. Are the units wrong?
ReplyDeleteAre you using point instead of comma? Also be careful about unit, you have to choose the right one. In DICOM DAP has dGy*cm2.
DeleteI want to convert DAP of humerus to effective dose but It doesn’t have humerus to select so Can I select shoulder instead????
ReplyDeleteIs an number that follow the protocol is conversion coefficient????
