Ụdị nyocha atọ a na-ahụkarị (nke a na-akpọkwa ultrasonic transducers) bụ linear, convex, na usoro nhazi.Mkpebi ahịrị dị nso dị nso dị mma ma enwere ike iji ya mee nyocha arịa ọbara.Elu convex na-eme ka nyocha dị omimi, nke a pụrụ iji mee ihe maka nyocha afọ na ihe ndị ọzọ.Usoro nhazi nke nwere obere akara ukwu na obere oge, nke enwere ike iji maka nyocha obi, wdg.
Ihe mmetụta Linear
A na-ahazi kristal piezoelectric n'ahịrị, ọdịdị osisi ahụ bụ akụkụ anọ, na mkpebi dị nso dị n'ọhịa dị mma.
Nke abụọ, ugboro na ngwa nke transducers linear dabere ma a na-eji ngwaahịa ahụ maka onyonyo 2D ma ọ bụ 3D.Ndị ntụgharị Linear ejiri maka onyonyo 2D gbadoro ụkwụ na 2.5Mhz – 12Mhz.
Ị nwere ike iji ihe mmetụta a maka ngwa dị iche iche dị ka: nyocha vaskụla, venipuncture, visualization vaskụla, thoracic, thyroid, tendon, arthrogenic, intraoperative, laparoscopic, fotoacoustic imaging, ultrasound velocity change imaging.
Ndị ntụgharị Linear maka onyonyo 3D nwere oge etiti nke 7.5Mhz – 11Mhz.
Ị nwere ike iji ihe ntụgharị a: obi, thyroid, vaskụla ngwa carotid.
Ihe mmetụta convex
Mkpebi ihe onyonyo convex na-ebelata ka omimi na-abawanye, yana ugboro ya na ngwa ya dabere ma ejiri ngwaahịa ahụ maka onyonyo 2D ma ọ bụ 3D.
Dịka ọmụmaatụ, convex transducers maka onyonyo 2D nwere oge etiti nke 2.5MHz – 7.5MHz.Ị nwere ike iji ya maka: nyocha afọ, nyocha transvaginal na transrectal, nchọpụta akụkụ ahụ.
Ihe ntụgharị convex maka onyonyo 3D nwere nnukwu nlele anya yana ugboro etiti nke 3.5MHz-6.5MHz.Ị nwere ike iji ya maka nyocha afọ.
Ihe mmetụta Array agba agba
Onye ntụgharị a, aha ya bụ nhazi nke kristal piezoelectric, nke a na-akpọ usoro nhazi, bụ kristal a na-ejikarị eme ihe.Ebe oghere ya dị warara mana ọ na-agbasa dịka ugboro ngwa ngwa.Ọzọkwa, ọdịdị osisi ahụ fọrọ nke nta ka ọ bụrụ triangular na mkpebi dị nso na-adịghị mma.
Anyị nwere ike iji ya maka: nyocha obi, gụnyere ule transesophageal, ule afọ, nyocha ụbụrụ.
