Ukuhlolwa kweveki nganye
- Hlola intloko yetyhubhu ukuba ayivuzi na ioyile. Ioyile yokukhusela igesi isebenza njengesigqubuthelo sombane kwaye iyindlela ephambili yokudlulisa ubushushu. Amanqanaba aphantsi eoyile abangela ukugoba kunye nokuwohloka ngokukhawuleza.
- Qinisekisa ukuhambelana kokuvezwa. Ukuba uqaphela ingxolo yomfanekiso eyandayo okanye ukwehla komahluko ngokuhamba kwexesha, ityhubhu isenokuba ifikelela esiphelweni sobomi—okanye ukulinganiswa kwejenereyitha kusenokuba kuhambile.
Ulondolozo lwekota nolonyaka
- Jonga ulungelelwaniso lwe-collimator. I-collimation engalunganga inokubangela ukuba umqadi unqumle umphetho wendlu, uvelise izinto zakudala kwaye uveze indlu kumonakalo wemitha engeyomfuneko.
- Linganisa isiphumo semitha kunye ne-HVL. Ingcali yefiziksi yezonyango okanye igosa lokhuseleko lwemitha kufuneka liqinisekise ukuba isiphumo kunye nomgangatho wemitha zihlala ngaphakathi kwemilinganiselo. Ukwehla kwesiphumo kwisetingi efanayo yendlela kubonisa ukuguga kwetyhubhu.
- Hlola iintambo kunye nezihlanganisi ezine-voltage ephezulu. Ubushushu obuqhekekileyo okanye izihlanganisi ezigqwalileyo kwandisa umngcipheko wokuqhekeka, okunokonakalisa zombini ityhubhu kunye nejenereyitha.
Ukugcinwa kunye nokuphathwa
- Ungaze uwise okanye uvale i-tube assembly. Ulungelelwaniso lwe-anode-cathode kwi-dental tube luchaneke kakhulu ukuya kumaqhezu e-millimeter. Umothuko woomatshini unokutshintsha olu lungelelwaniso, utshabalalise umgangatho womfanekiso.
- Gcina iityhubhu ezingasetyenziswanga kwiphakheji yazo yokuqala, kwindawo eyomileyo, kubushushu begumbi. Ubushushu obugqithisileyo okanye ukubanda kakhulu kunokuphazamisa isitywina se-vacuum.
- Xa ufaka ityhubhu yokutshintsha, landela imiqathango yomenzi ye-torque yezixhobo zokufakela kunye nenkqubo ecetyiswayo yokuzalisa ioyile. Iibholithi zokufakela eziqinisiweyo zinokucinezela i-glove yeglasi; ioyile engaphantsi kokugcwalisa ishiya iipokotho zomoya ezithintela ubushushu kunye nokupholisa.
