Umshini we-CT kwicandelo logqirha sele lisetyenziswe ngokubanzi phantse zonke izibhedlele ezingentla kwinqanaba le-county kunye nokulungiselelwa kwezixhobo zonyango. Ngoko ke, iinkonzo zonyango zivame ukudibana kumatshini. Ngoku sibheka ngokufutshane isiseko esisisiseko somshini we-CT kunye nomthombo oyintloko wokungaphumeleli.

 

 

A, ulwakhiwo olusisiseko lomatshini we-CT

 

Emva kweminyaka yokuphuhliswa, isakhiwo somatshini weTCT siphuculwe kakhulu, ukwandisa iindawo zomtshini, ukukhawulezisa ukukhawuleza ukukhawuleza. Iintlobo zininzi. Kodwa ukwakhiwa kwayo kubaluleke kakhulu kwi-hardware enye, kukho iindawo ezintathu eziphambili:

 

I-1, iyingxenye kunye kunye ne-X-ray umtshini we-detector.

 

I-2 yi-console ngekhompyutha

 

3, ukuphakamisa ibhedi yesigulane.

 

Ulwakhiwo kunye nomsebenzi ukusuka kwinqanaba lembono linokuhlulwa kwi: ukulawula ukukhangela kwikhompyutheni kunye nokwakhiwa komfanekiso wenxalenye yecandelo lomatshini wesigulane ukubeka iskripthi kunye nokulala phantsi. Ukuvelisa i-X-ray generator kunye ne-X-ray tube kwaye ukhuphe ulwazi kunye nendawo yokubona idatha. Ngokwale miba ebalulekileyo yecandelo le-CT ayiphumelelanga ukucacisa ukuthotyelwa kwesiseko esisisiseko kwaye kukho isiseko.

 

 

 

Uhlobo lwe-CT yomatshini wesiphene, imithombo kunye neempawu

 

I-CT ibangela ukuba ukuhluleka kungahlukaniswa zibe zintathu iintlobo: Okokuqala, ngenxa yemeko yendalo yenze ukuba ukuhluleka akuqhelekanga. Okwesibini kubangelwa ukusebenza kakubi kwephulo. Okwesithathu, icandelo le-CT yokuguga ngokwayo, utshintsho olulungileyo. Ukuhamba kweparamitha okukhokelela ekugqibeleni okanye ukuhluleka.

 

 

 

Ukuhluleka kwe-1 yemeko yendalo

 

Njengoko lokushisa kwegumbi le-CT, umswakama, iqondo lokuhlanjululwa komoya, ukuzinza kwe-CT ukuphelelwa kwamandla kubangelwa yimitshintsho kwimeko engqongileyo esiyibiza ngokuba yi-failure. Umzekelo: ukungena kwemimoya ephosakeleyo, ukushisa kwegumbi eliphezulu kakhulu kuya kubakho kwizixhobo ezithile (ezifana nokunikezelwa kwamandla okanye i-transformer) ngaphezulu okanye ukutsha, umonakalo webhodi yamasekethe. Ukuphazamiseka kokukhusela umatshini, iifowuni kunye neesekethe ezichaphazelekayo zivelisa ukushisa okugqithiseleyo kunye nezinye izixhobo zokusebenza; I-CT supply voltage surges ingabangela ukuba ikhomputer ingasebenzi kakuhle, umshini ungasebenzi, kwaye ingcinezelo ayiyinto eqhelekileyo, ukungazinzi kwe-X, ekugqibeleni kukukhokelela kumgangatho wesithombe, njl. Ukuhlanjululwa komoya akuyona into enhle yokungcola ngokukhawuleza iholele kwikhompyutheni yobomi obunzima. Inombolo ye-optical signal transmission transmission function due to dust accumulation of lead; ukuba umswakama mkhulu kakhulu, kuya kubangela ukuhluleka kweefowuni zeekhompyutheni. Imiba engqongileyo okanye ngokungekho ngqo ibangelwa yi-CT yingozi kakhulu, nokuba yenze umonakalo ongunaphakade. Ngoko ke, indawo yokusebenza ngokusemandleni, i-CT iphutha elingaphantsi, ubomi obuninzi benkonzo.

 

 

 

I-2 iphutha lomntu elibangelwa ukungafanelekanga ukusebenza

 

Iimeko eziqhelekileyo zokuphosakela ngabantu zi: ukungabi nesikhathi okanye ukulungiswa kwenkqubo yokufudumala, okubangele ukufana komfanekiso akuqhelekanga okanye kulungile, kubangelwa i-CT yokuba iziphene zokubeka isigulane azivumelekanga ukuba zihluthe umfanekiso; izigulane zithatha umfanekiso wesinyithi owenziwe ngumveliso; ngexesha elifanayo kukhokelela kwiintlobo ezahlukeneyo zokuqhuma kwe-CT; ukhethe iiparitha zeeskenazi zandise imifanekiso yeempahla ngenxa yokungafanelekanga njalo njalo. I-CT ivame ukuphutha komntu, ayiyi kuholela kwimiphumo emibi, nje kuphela ukuba zichonge izizathu zenkqubo ezichanekileyo zokuqalisa kwakhona okanye ukuvala ukuvala, ngokubanzi ziya kukwazi ukuphumelela ngxaki.

 

 

 

I-3 · Izixhobo ze-CT zonakalisa ukungaphumeleli kwazo kwimveliso

 

Ukungeniswa kwe-CT eninzi ekhulileyo kuhambelana nemithetho yobuninzi bokungabikho kwexesha lokungaphumeleli kwexesha, kwakungumgangatho onokusilela, obeka izinga lokungaphumeleli kwiinyanga ezintandathu zokuqala, inyanga ezintandathu emva kwexesha elide (5- Iminyaka eyi-8) ngexesha elide lizinzileyo ezisixhenxe okanye ezisibhozo kwaye emva koko zaqala ukwanda kancane.

 

ukusilela kwamalungu oomatshini

 

Oku kulandelwa ikakhulu kulezi zipho ezintathu ezinkulu;

 

Ngobomi obunyuliweyo bezinto zokusebenza, ukuhluleka komatshini kodwa kunye nokwanda ngonyaka. I-CT yasekuqaleni isetyenziselwa ukutshintsha imimoya yokujikeleza ejikelezayo kwisithuba somjikelezo wokuskena ukugqiba isantya esifutshane kakhulu sokujikeleza - ifanayo - ephuza ukuyeka, kwaye iphindaphindiwe rhoqo, iholele kumlinganiselo ophezulu wokusilela komatshini. Ngokomzekelo, isantya sivame ukubonakala singaqiniseki, kulula ukuvelisa kude kakhulu ukulawula, ukubetha, ukubetha, ibhande elinzima kakhulu. Yaye inxiba yembatho, ukuphulwa kunye nezinye iintsilelo. Namhlanje ininzi ye-CT isebenzisa i-slide ring technology, enye indlela yokujikeleza efanayo, kunye nomnye umashini ophezulu ekusetyenziseni ubuchwepheshe be-magnetic drive. Nangona kunjalo, ngenxa yokusetyenziswa kweendandatho zesalathisi, kwakhona kuzisa enye iphoso, ngenxa yokuba isalathisi sijikeleze ukutshatyalaliswa kwexesha elide kuya kubakho ukuxhatshazwa kwexesha elide, kwaye kubangele uchungechunge lwezandla zokungatshintshwa kwamandla kunye nokusebenzisa umbane, njengokugqithisa ukulawula, ukuphakama ukulawula uxinzelelo, ukutshitshiswa (indwangu ephakamileyo ephezulu), Ezinye (slip ukudluliselwa kwendandatho) ukulahleka kwempawu. Ngoko qi Ezinye izixhobo zithinteka ukusilela komatshini, ezifana ne-X-ray collimator inxalenye yokucwangcisa kulula ukuphuma ngaphandle kokulawula, unamathele; ukungaphumeleli komqhubi emva komsebenzi wesikhathi eside; Isalathisi sokulawula umjikelezo we-generator ye-pulse sinokuvela ngenxa yokugqoka okanye ukulimala njengokulahlekelwa kweentlobo ze-pulse.

 

b · X-ray yinxalenye yempazamo evelisiweyo

 

I-X-ray CT yokuvelisa ukuveliswa komatshini ukusuka kumacandelo alandelayo: i-inverter ephezulu, i-high-tension transformers, i-tube-ray kunye nomphathi wesiphaluka, i-cable high voltage. Enye inxalenye ye-inverter eyona nto isetyenziselwa ukuguqula ibe yi-frequency-frequency eyongeziweyo kwi-primary-transformer transformer primary. Iziphene eziqhelekileyo zi:

 

(1) ukuhluleka kwe-ray ye-tube ngokwalo: njengokutshintsha kwe-anode ukuhluleka, kubonakaliswe njengengxolo enkulu ejikelezayo. Kunzima ukutshintsha. Ukunyuka, ukuvezwa okuveliswe xa iziganeko ze-anode zijikeleza; i-filament ingxenye yecala, i-filament away. Isizathu asikho imisebe; I-X-ray yeglasi yeglasi yecala lokusilela ukuvuza ukungaphumeleli okubangelwa ukuphuka okanye ukuvuza, ukungabonakali, ukunyuka kwe-vacuum, ukutshaya kwamanzi kunye nokunye.

 

(2) ivelise inxalenye ephezulu yokhuselo: ukungaphumeleli kwesekethe, ukuchithwa, njl, i-high-voltage transformer-circuit circuit, i-high voltage capacitor ignition, breakdown. Ezi ntsilelo zidla ngokubangela ukuba i fuse ihambelane. Ngelo xesha azinako ukutyhila, okanye ukuvezwa kokukhuseleka ngokuzenzekelayo kokuphazamiseka.

 

(3) i-error-high power cable: i-connect connector isilawulekile, ibangela ukutshabalalisa, i-over-voltage okanye ukuphakama kwamandla, i-high voltage cable ekuqaleni kwe-CT X-ray yokujikeleza ityhubhu emva kokusebenzisa ixesha elide, -i-cables ignition cables, ezi ntsilelo ziya kuhambelana nomfesane ogqityiweyo.

 

c · Inxalenye yekhompyuter yempazamo

 

Ukuhluleka kwecandelo lekhompyutheni kunokwenzeka ukuba kuncinci, kulula ukulungisa, njengebhodibhodi eqhelekileyo, imouse, i-trackball, ezinye iingxaki ezincinci. Ininzi yidiski ekhuni, i-tape drive, ukuhluleka kwe-magneto-optical, okubangelwa yidiski enzima kunye nokusetyenziswa okungaphezulu kwexesha elide, ukunyuka kwendawo embi, kwikhokelela kumonakalo omkhulu.
