@@RadiographywithMrM what is penumbra in xray ?

[@RadiographywithMrM]

@@MadinayKaMusafir Penumbra is a term related to blur or the unsharpness of the shadow. We work of the shadow effect in radiography. If we increase the OID, decrease the SID, or increase the focal spot size then penumbra would increase but this was more prevalent in film imaging. It is not as visually apparent on digital now.
