Xa kuziwa kumfanekiso wezonyango, iteknoloji ye-X-ray sisixhobo esixabisekileyo esinokunika ulwazi olubalulekileyo lokuxilonga.Oomatshini beX-reyi baneenxalenye ezininzi, kwaye enye into ebalulekileyo yileIgridi yeX-ray.Igridi yeX-reyi isetyenziselwa ukuphucula umgangatho womfanekiso ngokunciphisa i-scatter radiation kunye nokuphucula ukungafani komfanekiso.Ukukhetha igridi yeX-reyi efanelekileyo yeyakhoUmatshini weX-reyiibalulekile ekuqinisekiseni iziphumo zomfanekiso ochanekileyo nezicacileyo.Kweli nqaku, siza kuxoxa ngezinto ekufuneka ziqwalaselwe xa ukhetha igridi yeX-reyi kumatshini wakho weX-reyi.
Ngaphambi kokuba sihlolisise inkqubo yokhetho, makhe siqonde iziseko zegridi yeX-reyi.Igridi ye-X-reyi sisixhobo esinemigca yelothe ecekethekileyo etshintshanayo nesixhobo sokusasazeka ngemitha.Umsebenzi ophambili wegridi kukufunxa imitha yokusasazeka evela xa iifoto zeX-reyi zidibana nomzimba womguli.Imitha yokusasazeka inokunciphisa kakhulu umgangatho womfanekiso ngokuvelisa imvelaphi emdaka eyaziwa ngokuba "yimigca yegridi."Ngokufunxa i-scatter radiation, iigridi ze-X-ray zinceda ukunyusa umahluko wemifanekiso, okukhokelela kwimifanekiso ebukhali.
Eyona nto ibalulekileyo ekufuneka iqwalaselwe xa ukhetha igridi ye-X-ray ngumlinganiselo wayo.Umlinganiselo wegridi ubhekiselele kubude bemigca yokukhokela xa kuthelekiswa nomgama phakathi kwabo.Olona luhlu luqhelekileyo lwegridi yi-6:1, 8:1, 10:1, kunye ne-12:1.Imilinganiselo yegridi ephezulu ibonelela ngokufunxwa ngcono kwemitha yokusasazeka kodwa ifuna izinto eziphezulu zobugcisa be-X-reyi.Ngokubanzi, umlinganiselo wegridi oyi-10:1 okanye 12:1 ilungile kwiradiyografi ngokubanzi, njengoko isusa ngokufanelekileyo ukusasazeka kwemitha ngaphandle kokunyusa idosi yesigulana ngokugqithisileyo.
Omnye umba obalulekileyo kukuhamba kwegridi, emele inani lemigca yokukhokela nge-intshi okanye isentimitha.Iifrikhwensi zegridi eziphezulu zikhokelela kwimigca yokukhokela emincinci nancinci, ephucula umgangatho womfanekiso kodwa inyusa ixabiso legridi yeX-reyi.Igridi yefrikhwensi yemigca eli-103 nge-intshi nganye okanye imigca engama-40 ngesentimitha iqhele ukusetyenziswa kwiradiyografi ngokubanzi.Nangona kunjalo, iifrikhwensi zegridi eziphezulu, njengemigca eyi-178 nge-intshi nganye okanye imigca engama-70 ngesentimitha nganye, iyacetyiswa kwiinkqubo zokucinga ezikhethekileyo ezifuna umgangatho womfanekiso ophezulu.
Ukongeza kumlinganiselo wegridi kunye nobuninzi, imathiriyeli yegridi nayo ibalulekile.Izinto ezahlukeneyo, ezifana ne-aluminiyam, i-carbon fiber, kunye neegridi ezixutyiweyo, zisetyenziswa ekwenzeni iigridi zeX-ray.Iigridi ze-aluminiyam zezona zisetyenziswa ngokuqhelekileyo ngenxa yeendleko-zokusebenza kunye nobuchule obuhle bokufunxa.Nangona kunjalo, zivame ukuba nzima kwaye zinokubangela ukuthotywa komfanekiso ukuba azihambelani ngokufanelekileyo kunye ne-X-ray beam.Iigridi zeCarbon fiber zikhaphukhaphu kwaye zibonelela ngeempawu ezibalaseleyo zokufunxa, kodwa zibiza kakhulu.Iigridi ze-Hybrid zidibanisa izibonelelo zombini ze-aluminium kunye ne-carbon fiber grids, ukubonelela ngebhalansi elungileyo phakathi kweendleko kunye nokusebenza.
Kukwabalulekile ukuqwalasela uluhlu lwegridi, olubhekiselele kuluhlu lwemigama ye-X-reyi ityhubhu ukuya kwigridi apho igridi isebenza ngokugqibeleleyo.Oomatshini beX-reyi abohlukeneyo baneemfuno ezahlukeneyo zoluhlu olugxininisiweyo, kwaye ukukhetha igridi ehambelana neenkcukacha zomatshini wakho kubalulekile.Ukusebenzisa igridi ngaphandle koluhlu logxininiso olucetyiswayo kunokukhokelela kumgangatho ongaphantsi komfanekiso kunye nokwanda kwedosi yesigulana.
Okokugqibela, ubungakanani begridi kufuneka buhambelane nobukhulu bendawo yokucinga yomatshini weX-ray.Ukusebenzisa igridi encinci kakhulu kunokukhokelela ekusikeni kwegridi, apho imiphetho yegridi ithintela umqadi weX-reyi, okukhokelela kumgangatho ombi womfanekiso.Ngakolunye uhlangothi, igridi enkulu kakhulu ayinako ukulingana ngokufanelekileyo okanye ukwandisa umthamo wesigulane ngokungeyomfuneko.
Ekugqibeleni, ukukhetha okulungileyoIgridi yeX-raykuba umatshini wakho weX-reyi ubalulekile ekufumaneni iziphumo zemifanekiso ekumgangatho ophezulu.Izinto ezinje ngomlinganiselo wegridi, amaxesha amaninzi, imathiriyeli, uluhlu olugxininisiweyo, kunye nobukhulu kufuneka ziqwalaselwe ngononophelo ukuqinisekisa ukusebenza kakuhle.Uthethwano kunyeIzixhobo zeX-reyiabavelisi okanye iingcaphephe zeradiology zinokubonelela ngesikhokelo esixabisekileyo ekukhetheni igridi yeX-reyi efanelekileyo kwiimfuno zakho zomfanekiso.
