Xa kuziwa koomatshini beX-reyi, iI-X-ray collimatorlicandelo elibalulekileyo elinceda ukulawula ubungakanani kunye necala le-X-reyi.Oku kubalulekile ekuqinisekiseni ukuba isigulana sifumana umlinganiselo ofanelekileyo wokuvezwa ngemitha nokuba umfanekiso oveliswayo ungowomgangatho ophezulu.Kukho iintlobo ezimbini eziphambili ze-X-ray collimators - manual kunye nombane.Zombini zineengenelo kunye nezingeloncedo zazo, kwaye kubalulekile ukuziqonda ezi ukuze ukhethe eyona ilungileyo kwiimfuno zakho.
A manual X-reyi collimatorisetyenziswa ngesandla kwaye iiparamitha zokudibanisa zisetwa ngesandla yiradiographer.Oku kuthetha ukuba ubungakanani kunye nokuma kwe-X-ray beam kulungelelaniswa kusetyenziswa amaqhosha okanye ukutshintsha kwi-collimator.Enye yeenzuzo eziphambili ze-collimator ye-manual kukuba ifikeleleka ngakumbi kune-collimator yombane.Kwakhona kulula ukuyisebenzisa kwaye ayifuni naluphi na uqeqesho olukhethekileyo.
Kwelinye icala, iumbane X-ray collimatorinikwe amandla ngumbane kwaye iiparamitha zokudibanisa zisetwa ngokuzenzekelayo.Oku kuthetha ukuba ubungakanani kunye nokumila kwe-X-ray beam kulawulwa ngokucofa amaqhosha okanye usebenzisa i-interface yesikrini sokuchukumisa.Enye yeenzuzo eziphambili ze-collimator yombane kukuba ichanekile kwaye ihambelana ne-collimator ye-manual.Ikwavumela iifitsha eziphambili ezinje ngokubeka indawo ngokuzenzekelayo kunye nolawulo olukude.
Xa kuziwa ekukhetheni phakathi kwe-collimator yombane kunye ne-X-ray yombane, kukho izinto ezimbalwa ekufuneka ziqwalaselwe.Okokuqala nokuphambili, kubalulekile ukuqwalasela iimfuno ezithile zomsebenzi wakho okanye indawo.Umzekelo, ukuba usebenza kwisibhedlele esixakekileyo okanye kwiklinikhi apho ixesha libaluleke kakhulu, i-collimator yombane inokuba lolona khetho lungcono njengoko lunokugcina ixesha kunye nokuphucula ukuhamba komsebenzi.Kwelinye icala, ukuba usebenza kwindawo encinci apho iindleko zixhalabisayo, i-collimator yezandla inokuba lolona khetho lusebenzayo.
Enye into ebalulekileyo ekufuneka iqwalaselwe linqanaba lobuchule babaqhubi.I-Manuwali ye-X-ray collimator ifuna ukuba umqhubi abe nokuqonda kakuhle kwe-X-ray physics kunye nemigaqo ye-imaging ukwenzela ukuseta iiparameters zokudibanisa ngokuchanekileyo.Ngakolunye uhlangothi, i-collimator yombane inokuthi isebenziseke ngakumbi kwaye ifuna uqeqesho oluncinci.
Kwakhona kubalulekile ukuqwalasela iindleko zexesha elide kunye neemfuno zokugcinwa kwe-collimator.Nangona i-collimator yombane ingaba neendleko eziphezulu zokuqala, inokufuna ukugcinwa okuncinci kunye nokulungiswa kwexesha.Kwelinye icala, i-collimator eyenziwe ngesandla inokungabizi kakhulu ukuyithenga ekuqaleni, kodwa inokufuna ukulungiswa rhoqo kunye nokulungiswa.
Ukuqukumbela, zombini ii-collimators ze-X-ray ze-manual kunye nombane zineenzuzo zabo kunye nokungalunganga.Ukhetho olufanelekileyo luxhomekeke kwiimfuno ezithile zomsebenzi wakho okanye indawo, kunye nenqanaba lobuchule babaqhubi kunye neendleko zexesha elide.Kubalulekile ukuyiqwalasela ngenyameko le miba phambi kokuba wenze isigqibo.Ekugqibeleni, injongo kukukhetha i-collimator eya kubonelela ngemifanekiso ephezulu ngelixa iqinisekisa ukhuseleko lwezigulane zombini kunye nabaqhubi.
