Njengoko sonke siyazi ukuba ukucaca komfanekiso we-ultrasound kuqinisekisa ukuba ukuxilongwa kwethu kuchanekile, Ukongeza ekusebenzeni komatshini, ngokwenene sinezinye iindlela zokuphucula ukucaca komfanekiso.
Ukongezelela koko sikukhankanyileyo kwinqaku elidlulileyo, ezi zinto zilandelayo ziya kuchaphazela imifanekiso ye-ultrasound.
1. Isigqibo
Kukho izisombululo ezintathu eziphambili ze-ultrasound: isisombululo sendawo, isisombululo sexesha kunye nesisombululo sokuchasana.
● Isisombululo sesithuba
Isisombululo se-Spatial yikhono le-ultrasound ukuhlukanisa amanqaku amabini kubunzulu obuthile, ulwahlulwe kwisisombululo se-axial kunye nesisombululo secala.
Isisombululo se-Axial kukukwazi ukwahlula phakathi kwamanqaku amabini kwicala elihambelana nomqadi we-ultrasound (longitudinal), kwaye ilingana ne-transducer frequency.
Isisombululo se-axial se-high-frequency probe siphezulu, kodwa kwangaxeshanye ukuthotywa kwezandi zomsindo kwi-tissue nakho kukhulu, okuya kubangela ukuba kulungiswe i-axial ephezulu yesakhiwo esinzulu, ngelixa isisombululo se-axial enzulu. Ulwakhiwo luphantsi noko, ndifuna ukuphucula isisombululo se-Axial sezakhiwo ezinzulu, mhlawumbi ngokuzisa ii-transducer ze-frequency ephezulu kufutshane nethagethi (umzekelo, i-transesophageal echocardiography) okanye ngokutshintshela kwii-transducer ezisezantsi-frequency.Kungenxa yoko le nto kucetyiswa ukuba kusetyenziswe i-high-frequency probes kwi-superficial tissue ultrasound kunye ne-low-frequency probes kwi-ultrasound yezicubu ezinzulu.
Isisombululo se-Lateral yikhono lokuhlukanisa amanqaku amabini e-perpendicular ukuya kwicala le-ultrasonic beam (horizontal).Ukongeza ekulinganiseni ukuphindaphinda kweprobe, ikwanxulumene ngokusondeleyo nokusetwa kogxininiso.Ububanzi be-ultrasonic beam yizona zincinci kwindawo ekugxilwe kuyo, ngoko ke isisombululo se-Lateral sisona sigxininise.Ngaphezulu sinokubona ukuba i-frequency kunye nokugxilwa kwe-probe kuhambelana ngokusondeleyo nesisombululo sendawo ye-ultrasound.1
Umfanekiso woku-1
● Isisombululo sexeshana
Isisombululo sexeshana, ekwaziwa ngokuba yireyithi yesakhelo, ibhekisa kwinani lezakhelo ngesekondi yomfanekiso.I-Ultrasound idluliselwa ngendlela ye-pulses, kwaye i-pulse elandelayo inokudluliselwa kuphela emva kokuba i-pulse yangaphambili ibuyele kwi-probe ye-ultrasound.
Isisombululo sexesha sinxulunyaniswa kakubi nobunzulu kunye nenani leengongoma ekugxilwe kuzo.Okukhona ubunzulu bukhulu kunye neendawo ekugxilwe kuzo ngakumbi, kokukhona usezantsi uphinda-phindo lwamaza okubetha kwaye usezantsi umyinge wesakhelo.Okukhona umfanekiso ucothayo, kokukhona ulwazi luncinci olubanjwa ngexesha elifutshane.Ngesiqhelo xa ireyithi yesakhelo ingaphantsi kwe24 izakhelo/s, umfanekiso uya kufinyaza.
Ngethuba lemisebenzi ye-anesthesia yeklinikhi, xa inaliti ihamba ngokukhawuleza okanye ichiza lifakwe ngokukhawuleza, izinga eliphantsi lefreyimu liya kubangela imifanekiso engabonakaliyo, ngoko ke isisombululo sexeshana sibaluleke kakhulu ekuboneni inaliti ngexesha lokuhlatywa.
Isisombululo sothelekiso sibhekisa kowona mahluko mncinane wesikali esingwevu esinokwahlulwa sisixhobo.Uluhlu lweDynamic lunxulumene ngokusondeleyo nesisombululo sokuchasana, ubukhulu boluhlu oluguquguqukayo, olusezantsi umahluko, umfanekiso ogudileyo, kunye nokuphakama kwamandla okuchonga izicubu ezibini ezifanayo okanye izinto (Umfanekiso 2).

2.Ukuphindaphinda
I-Frequency ihambelana ngokuthe ngqo nesisombululo sendawo kunye nokulinganisa ngokungafaniyo nokungena kwe-ultrasound (Umfanekiso 3).I-Frequency ephezulu, ubude obufutshane, ukuthomalalisa okukhulu, ukungangeni kakuhle, kunye nesisombululo esiphezulu sendawo.
Umfanekiso wesi-3
Kumsebenzi weklinikhi, iithagethi zemisebenzi emininzi zingaphaya, ngoko ke iiprobes zoluhlu olunesantya esiphezulu zinokuhlangabezana neemfuno zokusebenza zemihla ngemihla zoogqirha, kodwa xa udibana nezigulana ezityebileyo okanye iithagethi zokuhlatywa okunzulu (ezifana ne-lumbar plexus), i-convex array ephantsi. Uphando lukwabalulekile.
Uninzi lweeprobes ze-ultrasonic zangoku zi-broadband, esisiseko sokuqonda iteknoloji yokuguqula i-frequency.Ukuguqulwa kwamaxesha amaninzi kuthetha ukuba ukusebenza rhoqo kweprobe kunokutshintshwa xa usebenzisa iprobe efanayo.Ukuba ithagethi ingaphezulu, khetha amaza omoya aphezulu;ukuba ithagethi inzulu, khetha i-frequency ephantsi.
Ukuthatha i-Sonosite ultrasound njengomzekelo, ukuguqulwa kwayo rhoqo kuneendlela ze-3, ezizezi i-Res (isisombululo, siya kunika isisombululo esihle kakhulu), i-Gen (ngokubanzi, iya kunika ibhalansi engcono kakhulu phakathi kwesisombululo kunye nokungena), i-Pen (ukungena, iya kubonelela ngokungena ).Ngoko ke, kumsebenzi wangempela, kufuneka ulungelelaniswe ngokobunzulu bendawo ekujoliswe kuyo.
