RADIOGRAFIE ~ RÖNTGENSTRALEN

Van zwart naar wit:
Lucht < vet < water < eiwit/weefsels/organen < calcificaties/beenmerg < tanden/beenderen < contrast <
ijzer/lood/metaal
Dun < dik
Hoe zwarter: hoe minder absorptie / witter: meer absorptie


zwart = translucent = radiolucent = opklaring
wit = dens = radio opaak = schaduw


Absorptie x2 per 3 cm diktetoename => weefsels samendrukken (borst)


Liggende opname: suspine = ruglig prone = buiklig
PA (voorkeur) vs AP opname
Postero anterieur: straling rug – detector borst (staand)
Antero posterieur: straling borst – detector rug (liggend) => hart groter en ribben horizontaal en kleiner
longvolume
Laterale opname = profiel opname (meestal linkerkant ~ dichts bij hart)


INDICATIES
