Njengoba sonke sazi ukuthi ukucaca kwesithombe se-ultrasound kunquma ukuthi ukuxilongwa kwethu kunembile, Ngaphezu kokusebenza komshini, empeleni sinezinye izindlela zokuthuthukisa ukucaca kwesithombe.
Ngaphezu kwalokho esikushilo esihlokweni esandulele, izici ezilandelayo zizothinta izithombe ze-ultrasound.
1. Isinqumo
Kunezinqumo ezintathu ezinkulu ze-ultrasound: ukulungiswa kwendawo, ukulungiswa kwesikhathi, nokulungiswa kokuqhathanisa.
● Ukulungiswa kwendawo
Isixazululo sendawo yikhono le-ultrasound lokuhlukanisa amaphuzu amabili ekujuleni okuqondile, ahlukaniswe nge-axial resolution kanye ne-lateral resolution.
I-axial resolution yikhono lokuhlukanisa phakathi kwamaphoyinti amabili endaweni ehambisana ne-ultrasound beam (longitudinal), futhi ilingana nefrikhwensi ye-transducer.
Isixazululo se-axial se-high-frequency probe siphezulu, kodwa ngesikhathi esifanayo ukuncishiswa kwegagasi lomsindo emathangeni nakho kukhulu, okuzoholela ekuxazululeni okuphezulu kwe-axial yesakhiwo esingajulile, kuyilapho ukulungiswa kwe-axial yokujula. isakhiwo siphansi uma kuqhathaniswa, ngakho-ke ngifuna ukuthuthukisa ukulungiswa kwe-Axial kwezakhiwo ezijulile, ngokuletha ama-transducer anemvamisa ephezulu eduze nalokho okuhlosiwe (isb., i-transesophageal echocardiography) noma ngokushintshela kuma-transducer anefrikhwensi ephansi.Kungakho kunconywa ukuthi kusetshenziswe ama-high-frequency probes kuma-superficial tissue ultrasound kanye nama-low-frequency probes for deep tissue ultrasound.
Isixazululo se-Lateral yikhono lokuhlukanisa amaphuzu amabili perpendicular kuya isiqondiso sogongolo lwe-ultrasonic (evundlile).Ngaphezu kokulingana nemvamisa ye-probe, futhi ihlobene eduze nesilungiselelo sokugxilwa kuso.Ububanzi be-ultrasonic beam buncane kakhulu endaweni okugxilwe kuyo, ngakho-ke ukulungiswa kwe-Lateral kungcono kakhulu ekugxilweni.Ngenhla singabona ukuthi imvamisa nokugxila kwe-probe kuhlobene eduze nesinqumo sendawo ye-ultrasound.1

● Ukulungiswa kwesikhashana
Ukulungiswa kwesikhashana, okubuye kwaziwe ngezinga lozimele, kubhekisela enanini lozimele ngesekhondi ngayinye yokuthatha isithombe.I-Ultrasound idluliselwa ngesimo se-pulses, futhi i-pulse elandelayo ingadluliselwa kuphela ngemva kokuba i-pulse yangaphambili ibuyele ku-ultrasound probe.
Ukulungiswa kwesikhathi kuhlotshaniswa kabi nokujula kanye nenani lamaphoyinti okugxilwe kuwo.Uma kukhulu ukujula kanye namaphoyinti amaningi, kunciphisa imvamisa yokuphindaphinda ukushaya kwenhliziyo kanye nezinga lozimele.Ukuthatha isithombe kuhamba kancane, kuyancipha ulwazi oluthwetshulwa ngesikhathi esifushane.Ngokuvamile uma izinga lozimele lingaphansi kuka-24 ozimele/s, isithombe sizocwayiza.
Ngesikhathi sokusebenza kwe-anesthesia yomtholampilo, lapho inaliti ihamba ngokushesha noma umuthi ujovwe ngokushesha, izinga eliphansi lefreyimu lizodala izithombe ezifiphele, ngakho ukulungiswa kwesikhashana kubaluleke kakhulu ekuboneni inaliti ngesikhathi sokubhoboza.
Ukulungiswa kokugqama kubhekisela emehlukweni omncane wesilinganiso esimpunga ithuluzi elingawuhlukanisa.Ibanga elinamandla lihlobene eduze nokulungiswa kokugqama, ukuba likhulu kobubanzi obuguqukayo, ukwehla kokugqama, ukushelela kwesithombe, kanye nekhono eliphezulu lokuhlonza izicubu noma izinto ezimbili ezifanayo (Umfanekiso 2).

2.Imvamisa
Imvamisa ilingana ngokuqondile nokulungiswa kwendawo futhi ilinganisa ngokuphambene nokungena kwe-ultrasound (Umfanekiso 3).Imvamisa ephezulu, ubude begagasi obufushane, ukuncipha okukhulu, ukungangeni kahle, nokulungiswa kwendawo okuphezulu.
Umfanekiso 3
Emsebenzini womtholampilo, okuhlosiwe kokuhlinza okuningi kukha phezulu, ngakho-ke ama-probe alandelanayo anemvamisa ephezulu angahlangabezana nezidingo zokusebenza zansuku zonke zodokotela, kodwa lapho ehlangabezana neziguli ezikhuluphele noma okuhloswe ukubhoboza okujulile (okufana ne-lumbar plexus), I-low frequency convex array. i-probe nayo ibalulekile.
Iningi lamanje lama-ultrasonic probes yi-broadband, okuyisisekelo sokuqaphela ubuchwepheshe bokuguqulwa kwemvamisa.Ukuguqulwa kwemvamisa kusho ukuthi imvamisa yokusebenza ye-probe ingashintshwa uma kusetshenziswa uphenyo olufanayo.Uma ithagethi ingaphezulu, khetha imvamisa ephezulu;uma ithagethi ijulile, khetha imvamisa ephansi.
Ukuthatha i-Sonosite ultrasound njengesibonelo, ukuguqulwa kwemvamisa yayo kunezinhlobo ze-3, okungukuthi i-Res (isinqumo, izohlinzeka ngesinqumo esihle kakhulu), i-Gen (okujwayelekile, izohlinzeka ngokulinganisela okungcono kakhulu phakathi kokuxazulula nokungena), Ipeni (ukungena, izohlinzeka ngokungena okungcono kakhulu ).Ngakho-ke, emsebenzini wangempela, udinga ukulungiswa ngokuvumelana nokujula kwendawo okuhlosiwe.
